+title: Pulsar adaptor for Apache Kafka
+sidebar_label: "Kafka client wrapper"
+original_id: adaptors-kafka
+---
+
+
+Pulsar provides an easy option for applications that are currently written using the [Apache Kafka](http://kafka.apache.org) Java client API.
+
+## Using the Pulsar Kafka compatibility wrapper
+
+In an existing application, change the regular Kafka client dependency and replace it with the Pulsar Kafka wrapper. Remove the following dependency in `pom.xml`:
+
+```xml
+
+<dependency>
+  <groupId>org.apache.kafka</groupId>
+  <artifactId>kafka-clients</artifactId>
+  <version>0.10.2.1</version>
+</dependency>
+
+```
+
+Then include this dependency for the Pulsar Kafka wrapper:
+
+```xml
+
+<dependency>
+  <groupId>org.apache.pulsar</groupId>
+  <artifactId>pulsar-client-kafka</artifactId>
+  <version>@pulsar:version@</version>
+</dependency>
+
+```
+
+With the new dependency, the existing code works without any changes. You need to adjust the configuration, and make sure it points the
+producers and consumers to Pulsar service rather than Kafka, and uses a particular
+Pulsar topic.
+
+## Using the Pulsar Kafka compatibility wrapper together with existing kafka client
+
+When migrating from Kafka to Pulsar, the application might use the original kafka client
+and the pulsar kafka wrapper together during migration. You should consider using the
+unshaded pulsar kafka client wrapper.
+
+```xml
+
+<dependency>
+  <groupId>org.apache.pulsar</groupId>
+  <artifactId>pulsar-client-kafka-original</artifactId>
+  <version>@pulsar:version@</version>
+</dependency>
+
+```
+
+When using this dependency, construct producers using `org.apache.kafka.clients.producer.PulsarKafkaProducer`
+instead of `org.apache.kafka.clients.producer.KafkaProducer` and `org.apache.kafka.clients.producer.PulsarKafkaConsumer` for consumers.
+
+## Producer example
+
+```java
+
+// Topic needs to be a regular Pulsar topic
+String topic = "persistent://public/default/my-topic";
+
+Properties props = new Properties();
+// Point to a Pulsar service
+props.put("bootstrap.servers", "pulsar://localhost:6650");
+
+props.put("key.serializer", IntegerSerializer.class.getName());
+props.put("value.serializer", StringSerializer.class.getName());
+
+Producer<Integer, String> producer = new KafkaProducer(props);
+
+for (int i = 0; i < 10; i++) {
+    producer.send(new ProducerRecord<Integer, String>(topic, i, "hello-" + i));
+    log.info("Message {} sent successfully", i);
+}
+
+producer.close();
+
+```
+
+## Consumer example
+
+```java
+
+String topic = "persistent://public/default/my-topic";
+
+Properties props = new Properties();
+// Point to a Pulsar service
+props.put("bootstrap.servers", "pulsar://localhost:6650");
+props.put("group.id", "my-subscription-name");
+props.put("enable.auto.commit", "false");
+props.put("key.deserializer", IntegerDeserializer.class.getName());
+props.put("value.deserializer", StringDeserializer.class.getName());
+
+Consumer<Integer, String> consumer = new KafkaConsumer(props);
+consumer.subscribe(Arrays.asList(topic));
+
+while (true) {
+    ConsumerRecords<Integer, String> records = consumer.poll(100);
+    records.forEach(record -> {
+        log.info("Received record: {}", record);
+    });
+
+    // Commit last offset
+    consumer.commitSync();
+}
+
+```
+
+## Complete Examples
+
+You can find the complete producer and consumer examples [here](https://github.com/apache/pulsar-adapters/tree/master/pulsar-client-kafka-compat/pulsar-client-kafka-tests/src/test/java/org/apache/pulsar/client/kafka/compat/examples).
+
+## Compatibility matrix
+
+Currently the Pulsar Kafka wrapper supports most of the operations offered by the Kafka API.

+## Spark Streaming receiver
+The Spark Streaming receiver for Pulsar is a custom receiver that enables Apache [Spark Streaming](https://spark.apache.org/streaming/) to receive raw data from Pulsar.
+
+An application can receive data in [Resilient Distributed Dataset](https://spark.apache.org/docs/latest/programming-guide.html#resilient-distributed-datasets-rdds) (RDD) format via the Spark Streaming receiver and can process it in a variety of ways.
+
+### Prerequisites
+
+To use the receiver, include a dependency for the `pulsar-spark` library in your Java configuration.
+
+#### Maven
+
+If you're using Maven, add this to your `pom.xml`:
+
+```xml
+
+<!-- in your <properties> block -->
+<pulsar.version>@pulsar:version@</pulsar.version>
+
+<!-- in your <dependencies> block -->
+<dependency>
+  <groupId>org.apache.pulsar</groupId>
+  <artifactId>pulsar-spark</artifactId>
+  <version>${pulsar.version}</version>
+</dependency>
+
+```
+
+#### Gradle
+
+If you're using Gradle, add this to your `build.gradle` file:
+
+```groovy
+
+def pulsarVersion = "@pulsar:version@"
+
+dependencies {
+    compile group: 'org.apache.pulsar', name: 'pulsar-spark', version: pulsarVersion
+}
+
+```
+
+### Usage
+
+Pass an instance of `SparkStreamingPulsarReceiver` to the `receiverStream` method in `JavaStreamingContext`:
+
+```java
+
+    String serviceUrl = "pulsar://localhost:6650/";
+    String topic = "persistent://public/default/test_src";
+    String subs = "test_sub";
+
+    SparkConf sparkConf = new SparkConf().setMaster("local[*]").setAppName("Pulsar Spark Example");
+
+    JavaStreamingContext jsc = new JavaStreamingContext(sparkConf, Durations.seconds(60));
+
+    ConsumerConfigurationData<byte[]> pulsarConf = new ConsumerConfigurationData();
+
+    Set<String> set = new HashSet();
+    set.add(topic);
+    pulsarConf.setTopicNames(set);
+    pulsarConf.setSubscriptionName(subs);
+
+    SparkStreamingPulsarReceiver pulsarReceiver = new SparkStreamingPulsarReceiver(
+        serviceUrl,
+        pulsarConf,
+        new AuthenticationDisabled());
+
+    JavaReceiverInputDStream<byte[]> lineDStream = jsc.receiverStream(pulsarReceiver);
+
+```
+
+For a complete example, click [here](https://github.com/apache/pulsar-adapters/blob/master/examples/spark/src/main/java/org/apache/spark/streaming/receiver/example/SparkStreamingPulsarReceiverExample.java). In this example, the number of messages that contain the string "Pulsar" in received messages is counted.
+
+Note that if needed, other Pulsar authentication classes can be used. For example, in order to use a token during authentication the following parameters for the `SparkStreamingPulsarReceiver` constructor can be set:
+
+```java
+
+SparkStreamingPulsarReceiver pulsarReceiver = new SparkStreamingPulsarReceiver(
+        serviceUrl,
+        pulsarConf,
+        new AuthenticationToken("token:<secret-JWT-token>"));
+
+```
+

+
+Pulsar Storm is an adaptor for integrating with [Apache Storm](http://storm.apache.org/) topologies. It provides core Storm implementations for sending and receiving data.
+
+An application can inject data into a Storm topology via a generic Pulsar spout, as well as consume data from a Storm topology via a generic Pulsar bolt.
+
+## Using the Pulsar Storm Adaptor
+
+Include dependency for Pulsar Storm Adaptor:
+
+```xml

+## Pulsar Spout
+
+The Pulsar Spout allows for the data published on a topic to be consumed by a Storm topology. It emits a Storm tuple based on the message received and the `MessageToValuesMapper` provided by the client.
+
+The tuples that fail to be processed by the downstream bolts will be re-injected by the spout with an exponential backoff, within a configurable timeout (the default is 60 seconds) or a configurable number of retries, whichever comes first, after which it is acknowledged by the consumer. Here's an example construction of a spout:
+
+```java
+
+MessageToValuesMapper messageToValuesMapper = new MessageToValuesMapper() {
+
+    @Override
+    public Values toValues(Message msg) {
+        return new Values(new String(msg.getData()));
+    }
+
+    @Override
+    public void declareOutputFields(OutputFieldsDeclarer declarer) {
+        // declare the output fields
+        declarer.declare(new Fields("string"));
+    }
+};
+
+// Configure a Pulsar Spout
+PulsarSpoutConfiguration spoutConf = new PulsarSpoutConfiguration();
+spoutConf.setServiceUrl("pulsar://broker.messaging.usw.example.com:6650");
+spoutConf.setTopic("persistent://my-property/usw/my-ns/my-topic1");
+spoutConf.setSubscriptionName("my-subscriber-name1");
+spoutConf.setMessageToValuesMapper(messageToValuesMapper);
+
+// Create a Pulsar Spout
+PulsarSpout spout = new PulsarSpout(spoutConf);
+
+```
+
+For a complete example, click [here](https://github.com/apache/pulsar-adapters/blob/master/pulsar-storm/src/test/java/org/apache/pulsar/storm/PulsarSpoutTest.java).
+
+## Pulsar Bolt
+
+The Pulsar bolt allows data in a Storm topology to be published on a topic. It publishes messages based on the Storm tuple received and the `TupleToMessageMapper` provided by the client.
+
+A partitioned topic can also be used to publish messages on different topics. In the implementation of the `TupleToMessageMapper`, a "key" will need to be provided in the message which will send the messages with the same key to the same topic. Here's an example bolt:
+
+```java
+
+TupleToMessageMapper tupleToMessageMapper = new TupleToMessageMapper() {
+
+    @Override
+    public TypedMessageBuilder<byte[]> toMessage(TypedMessageBuilder<byte[]> msgBuilder, Tuple tuple) {
+        String receivedMessage = tuple.getString(0);
+        // message processing
+        String processedMsg = receivedMessage + "-processed";
+        return msgBuilder.value(processedMsg.getBytes());
+    }
+
+    @Override
+    public void declareOutputFields(OutputFieldsDeclarer declarer) {
+        // declare the output fields
+    }
+};
+
+// Configure a Pulsar Bolt
+PulsarBoltConfiguration boltConf = new PulsarBoltConfiguration();
+boltConf.setServiceUrl("pulsar://broker.messaging.usw.example.com:6650");
+boltConf.setTopic("persistent://my-property/usw/my-ns/my-topic2");
+boltConf.setTupleToMessageMapper(tupleToMessageMapper);
+
+// Create a Pulsar Bolt
+PulsarBolt bolt = new PulsarBolt(boltConf);
+
+```

+Pulsar brokers consist of two components:
+
+1. An HTTP server exposing a {@inject: rest:REST:/} interface administration and [topic](reference-terminology.md#topic) lookup.
+2. A dispatcher that handles all Pulsar [message](reference-terminology.md#message) transfers.
+
+[Brokers](reference-terminology.md#broker) can be managed via:
+
+* The `brokers` command of the [`pulsar-admin`](/tools/pulsar-admin/) tool
+* The `/admin/v2/brokers` endpoint of the admin {@inject: rest:REST:/} API
+* The `brokers` method of the `PulsarAdmin` object in the [Java API](client-libraries-java.md)
+
+In addition to being configurable when you start them up, brokers can also be [dynamically configured](#dynamic-broker-configuration).
+
+> See the [Configuration](reference-configuration.md#broker) page for a full listing of broker-specific configuration parameters.

+
+### Dynamic broker configuration
+
+One way to configure a Pulsar [broker](reference-terminology.md#broker) is to supply a [configuration](reference-configuration.md#broker) when the broker is [started up](reference-cli-tools.md#pulsar-broker).
+
+But since all broker configuration in Pulsar is stored in ZooKeeper, configuration values can also be dynamically updated *while the broker is running*. When you update broker configuration dynamically, ZooKeeper will notify the broker of the change and the broker will then override any existing configuration values.
+
+* The [`brokers`](reference-pulsar-admin.md#brokers) command for the [`pulsar-admin`](reference-pulsar-admin.md) tool has a variety of subcommands that enable you to manipulate a broker's configuration dynamically, enabling you to [update config values](#update-dynamic-configuration) and more.
+* In the Pulsar admin {@inject: rest:REST:/} API, dynamic configuration is managed through the `/admin/v2/brokers/configuration` endpoint.
+
+### Update dynamic configuration
+
+````mdx-code-block

+  defaultValue="pulsar-admin"
+  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"JAVA","value":"JAVA"}]}>
+<TabItem value="pulsar-admin">
+
+The [`update-dynamic-config`](reference-pulsar-admin.md#brokers-update-dynamic-config) subcommand will update existing configuration. It takes two arguments: the name of the parameter and the new value using the `config` and `value` flag respectively. Here's an example for the [`brokerShutdownTimeoutMs`](reference-configuration.md#broker-brokerShutdownTimeoutMs) parameter:

+Pulsar clusters consist of one or more Pulsar [brokers](reference-terminology.md#broker), one or more [BookKeeper](reference-terminology.md#bookkeeper)
+servers (aka [bookies](reference-terminology.md#bookie)), and a [ZooKeeper](https://zookeeper.apache.org) cluster that provides configuration and coordination management.
+
+Clusters can be managed via:
+
+* The `clusters` command of the [`pulsar-admin`](/tools/pulsar-admin/)) tool
+* The `/admin/v2/clusters` endpoint of the admin {@inject: rest:REST:/} API
+* The `clusters` method of the `PulsarAdmin` object in the [Java API](client-libraries-java.md)
+
+## Clusters resources
+
+### Provision
+
+New clusters can be provisioned using the admin interface.
+
+> Please note that this operation requires superuser privileges.
+
+````mdx-code-block

+
+You can provision a new cluster using the [`create`](reference-pulsar-admin.md#clusters-create) subcommand. Here's an example:
+

+);
+admin.clusters().createCluster(clusterName, clusterData);
+
+```
+
+</TabItem>
+
+</Tabs>
+````
+
+### Initialize cluster metadata
+
+When provision a new cluster, you need to initialize that cluster's [metadata](concepts-architecture-overview.md#metadata-store). When initializing cluster metadata, you need to specify all of the following:
+
+* The name of the cluster
+* The local metadata store connection string for the cluster
+* The configuration store connection string for the entire instance
+* The web service URL for the cluster
+* A broker service URL enabling interaction with the [brokers](reference-terminology.md#broker) in the cluster
+
+You must initialize cluster metadata *before* starting up any [brokers](admin-api-brokers.md) that will belong to the cluster.
+
+> **No cluster metadata initialization through the REST API or the Java admin API**
+>
+> Unlike most other admin functions in Pulsar, cluster metadata initialization cannot be performed via the admin REST API
+> or the admin Java client, as metadata initialization involves communicating with ZooKeeper directly.
+> Instead, you can use the [`pulsar`](reference-cli-tools.md#pulsar) CLI tool, in particular
+> the [`initialize-cluster-metadata`](reference-cli-tools.md#pulsar-initialize-cluster-metadata) command.
+
+Here's an example cluster metadata initialization command:
+
+```shell
+
+bin/pulsar initialize-cluster-metadata \
+  --cluster us-west \
+  --metadata-store zk:zk1.us-west.example.com:2181,zk2.us-west.example.com:2181/my-chroot-path \
+  --configuration-metadata-store zk:zk1.us-west.example.com:2181,zk2.us-west.example.com:2181/my-chroot-path \
+  --web-service-url http://pulsar.us-west.example.com:8080/ \
+  --web-service-url-tls https://pulsar.us-west.example.com:8443/ \
+  --broker-service-url pulsar://pulsar.us-west.example.com:6650/ \
+  --broker-service-url-tls pulsar+ssl://pulsar.us-west.example.com:6651/
+
+```
+
+You'll need to use `--*-tls` flags only if you're using [TLS authentication](security-tls-authentication.md) in your instance.
+
+### Get configuration
+
+You can fetch the [configuration](reference-configuration.md) for an existing cluster at any time.

+Pulsar [namespaces](reference-terminology.md#namespace) are logical groupings of [topics](reference-terminology.md#topic).
+
+Namespaces can be managed via:
+
+* The `namespaces` command of the [`pulsar-admin`](/tools/pulsar-admin/) tool
+* The `/admin/v2/namespaces` endpoint of the admin {@inject: rest:REST:/} API
+* The `namespaces` method of the `PulsarAdmin` object in the [Java API](client-libraries-java.md)

+### Configure backlog quota policies
+
+#### Set backlog quota policies
+
+Backlog quota helps the broker to restrict bandwidth/storage of a namespace once it reaches a certain threshold limit. Admin can set the limit and take corresponding action after the limit is reached.
+
+  1.  producer_request_hold: broker holds but not persists produce request payload
+
+  2.  producer_exception: broker disconnects with the client by giving an exception
+
+  3.  consumer_backlog_eviction: broker starts discarding backlog messages
+
+Backlog quota restriction can be taken care by defining restriction of backlog-quota-type: destination_storage.

+
+
+The Pulsar admin interface enables you to manage all important entities in a Pulsar instance, such as tenants, topics, and namespaces.
+
+You can interact with the admin interface via:
+
+- The `pulsar-admin` CLI tool, which is available in the `bin` folder of your Pulsar installation:
+
+  ```shell
+  
+  bin/pulsar-admin
+  
+  ```
+
+  > **Important**
+  > 
+  > For the latest and complete information about `Pulsar admin`, including commands, flags, descriptions, and more information, see [Pulsar admin doc](/tools/pulsar-admin/).
+
+- HTTP calls, which are made against the admin {@inject: rest:REST:/} API provided by Pulsar brokers. For some RESTful APIs, they might be redirected to the owner brokers for serving with [`307 Temporary Redirect`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/307), hence the HTTP callers should handle `307 Temporary Redirect`. If you use `curl` commands, you should specify `-L` to handle redirections.
+  
+  > **Important**
+  >
+  > For the latest and complete information about `REST API`, including parameters, responses, samples, and more, see {@inject: rest:REST:/} API doc.
+
+- A Java client interface.
+  
+  > **Important**
+  > 
+  > For the latest and complete information about `Java admin API`, including classes, methods, descriptions, and more, see [Java admin API doc](/api/admin/).
+
+> **The REST API is the admin interface**. Both the `pulsar-admin` CLI tool and the Java client use the REST API. If you implement your own admin interface client, you should use the REST API. 
+
+## Admin setup
+
+Each of the three admin interfaces (the `pulsar-admin` CLI tool, the {@inject: rest:REST:/} API, and the [Java admin API](/api/admin)) requires some special setup if you have enabled authentication in your Pulsar instance.
+
+````mdx-code-block

+  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
+<TabItem value="pulsar-admin">
+
+If you have enabled authentication, you need to provide an auth configuration to use the `pulsar-admin` tool. By default, the configuration for the `pulsar-admin` tool is in the [`conf/client.conf`](reference-configuration.md#client) file. The following are the available parameters:
+
+|Name|Description|Default|
+|----|-----------|-------|
+|webServiceUrl|The web URL for the cluster.|http://localhost:8080/|
+|brokerServiceUrl|The Pulsar protocol URL for the cluster.|pulsar://localhost:6650/|
+|authPlugin|The authentication plugin.| |
+|authParams|The authentication parameters for the cluster, as a comma-separated string.| |
+|useTls|Whether or not TLS authentication will be enforced in the cluster.|false|
+|tlsAllowInsecureConnection|Accept untrusted TLS certificate from client.|false|
+|tlsTrustCertsFilePath|Path for the trusted TLS certificate file.| |
+
+</TabItem>
+<TabItem value="REST API">
+
+You can find details for the REST API exposed by Pulsar brokers in this {@inject: rest:document:/}.
+
+</TabItem>
+<TabItem value="Java">
+
+To use the Java admin API, instantiate a {@inject: javadoc:PulsarAdmin:/admin/org/apache/pulsar/client/admin/PulsarAdmin} object, and specify a URL for a Pulsar broker and a {@inject: javadoc:PulsarAdminBuilder:/admin/org/apache/pulsar/client/admin/PulsarAdminBuilder}. The following is a minimal example using `localhost`:
+
+```java
+
+String url = "http://localhost:8080";
+// Pass auth-plugin class fully-qualified name if Pulsar-security enabled
+String authPluginClassName = "com.org.MyAuthPluginClass";
+// Pass auth-param if auth-plugin class requires it
+String authParams = "param1=value1";
+boolean useTls = false;
+boolean tlsAllowInsecureConnection = false;
+String tlsTrustCertsFilePath = null;
+PulsarAdmin admin = PulsarAdmin.builder()
+.authentication(authPluginClassName,authParams)
+.serviceHttpUrl(url)
+.tlsTrustCertsFilePath(tlsTrustCertsFilePath)
+.allowTlsInsecureConnection(tlsAllowInsecureConnection)
+.build();
+
+```
+
+If you use multiple brokers, you can use multi-host like Pulsar service. For example,
+
+```java
+
+String url = "http://localhost:8080,localhost:8081,localhost:8082";
+// Pass auth-plugin class fully-qualified name if Pulsar-security enabled
+String authPluginClassName = "com.org.MyAuthPluginClass";
+// Pass auth-param if auth-plugin class requires it
+String authParams = "param1=value1";
+boolean useTls = false;
+boolean tlsAllowInsecureConnection = false;
+String tlsTrustCertsFilePath = null;
+PulsarAdmin admin = PulsarAdmin.builder()
+.authentication(authPluginClassName,authParams)
+.serviceHttpUrl(url)
+.tlsTrustCertsFilePath(tlsTrustCertsFilePath)
+.allowTlsInsecureConnection(tlsAllowInsecureConnection)
+.build();
+
+```

+
+## How to define Pulsar resource names when running Pulsar in Kubernetes
+If you run Pulsar Functions or connectors on Kubernetes, you need to follow Kubernetes naming convention to define the names of your Pulsar resources, whichever admin interface you use.
+
+Kubernetes requires a name that can be used as a DNS subdomain name as defined in [RFC 1123](https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names). Pulsar supports more legal characters than Kubernetes naming convention. If you create a Pulsar resource name with special characters that are not supported by Kubernetes (for example, including colons in a Pulsar namespace name), Kubernetes runtime translates the Pulsar object names into Kubernetes resource labels w [...]
+
+- Truncate to 63 characters
+  
+- Replace the following characters with dashes (-):
+  
+  - Non-alphanumeric characters
+  
+  - Underscores (_)
+  
+  - Dots (.) 
+  
+- Replace beginning and ending non-alphanumeric characters with 0
+  
+:::tip
+
+- If you get an error in translating Pulsar object names into Kubernetes resource labels (for example, you may have a naming collision if your Pulsar object name is too long) or want to customize the translating rules, see [customize Kubernetes runtime](functions-runtime.md#customize-kubernetes-runtime).
+- For how to configure Kubernetes runtime, see [here](functions-runtime.md#configure-kubernetes-runtime).

+
+Package managers or package-management systems automatically manage packages in a consistent manner. These tools simplify the installation tasks, upgrade process, and deletion operations for users. A package is a minimal unit that a package manager deals with. In Pulsar, packages are organized at the tenant- and namespace-level to manage Pulsar Functions and Pulsar IO connectors (i.e., source and sink).
+
+## What is a package?
+
+A package is a set of elements that the user would like to reuse in later operations. In Pulsar, a package can be a group of functions, sources, and sinks. You can define a package according to your needs. 
+
+The package management system in Pulsar stores the data and metadata of each package (as shown in the table below) and tracks the package versions. 
+
+|Metadata|Description|
+|--|--|
+|description|The description of the package.|
+|contact|The contact information of a package. For example, an email address of the developer team.|
+|create_time|The time when the package is created.|
+|modification_time|The time when the package is lastly modified.|
+|properties|A user-defined key/value map to store other information.|
+
+## How to use a package
+
+Packages can efficiently use the same set of functions and IO connectors. For example, you can use the same function, source, and sink in multiple namespaces. The main steps are:
+
+1. Create a package in the package manager by providing the following information: type, tenant, namespace, package name, and version.
+
+   |Component|Description|
+   |-|-|
+   |type|Specify one of the supported package types: function, sink and source.|
+   |tenant|Specify the tenant where you want to create the package.|
+   |namespace|Specify the namespace where you want to create the package.|
+   |name|Specify the complete name of the package, using the format `<tenant>/<namespace>/<package name>`.|
+   |version|Specify the version of the package using the format `MajorVerion.MinorVersion` in numerals.|
+
+   The information you provide creates a URL for a package, in the format `<type>://<tenant>/<namespace>/<package name>/<version>`.
+
+2. Upload the elements to the package, i.e., the functions, sources, and sinks that you want to use across namespaces.
+
+3. Apply permissions to this package from various namespaces.
+
+Now, you can use the elements you defined in the package by calling this package from within the package manager. The package manager locates it by the URL. For example,
+
+```
+
+sink://public/default/mysql-sink@1.0
+function://my-tenant/my-ns/my-function@0.1
+source://my-tenant/my-ns/mysql-cdc-source@2.3
+
+```
+
+## Package management in Pulsar
+
+You can use the command line tools, REST API, or the Java client to manage your package resources in Pulsar. More specifically, you can use these tools to [upload](#upload-a-package), [download](#download-a-package), and [delete](#delete-a-package) a package, [get the metadata](#get-the-metadata-of-a-package) and [update the metadata](#update-the-metadata-of-a-package) of a package, [get the versions](#list-all-versions-of-a-package) of a package, and [get all packages of a specific type [...]

+Pulsar allows you to grant namespace-level or topic-level permission to users.
+
+- If you grant a namespace-level permission to a user, then the user can access all the topics under the namespace.
+
+- If you grant a topic-level permission to a user, then the user can access only the topic.
+
+The chapters below demonstrate how to grant namespace-level permissions to users. For how to grant topic-level permissions to users, see [manage topics](admin-api-topics.md/#grant-permission).
+
+## Grant permissions
+
+You can grant permissions to specific roles for lists of operations such as `produce` and `consume`.
+
+````mdx-code-block
+<Tabs 
+  defaultValue="pulsar-admin"
+  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
+<TabItem value="pulsar-admin">
+
+Use the [`grant-permission`](reference-pulsar-admin.md#grant-permission) subcommand and specify a namespace, actions using the `--actions` flag, and a role using the `--role` flag:
+
+```shell
+
+$ pulsar-admin namespaces grant-permission test-tenant/ns1 \
+  --actions produce,consume \
+  --role admin10
+
+```
+
+Wildcard authorization can be performed when `authorizationAllowWildcardsMatching` is set to `true` in `broker.conf`.
+
+e.g.
+
+```shell
+
+$ pulsar-admin namespaces grant-permission test-tenant/ns1 \
+                        --actions produce,consume \
+                        --role 'my.role.*'
+
+```
+
+Then, roles `my.role.1`, `my.role.2`, `my.role.foo`, `my.role.bar`, etc. can produce and consume.  
+
+```shell
+
+$ pulsar-admin namespaces grant-permission test-tenant/ns1 \
+                        --actions produce,consume \
+                        --role '*.role.my'
+
+```
+
+Then, roles `1.role.my`, `2.role.my`, `foo.role.my`, `bar.role.my`, etc. can produce and consume.
+
+**Note**: A wildcard matching works at **the beginning or end of the role name only**.
+
+e.g.
+
+```shell
+
+$ pulsar-admin namespaces grant-permission test-tenant/ns1 \
+                        --actions produce,consume \
+                        --role 'my.*.role'
+
+```
+
+In this case, only the role `my.*.role` has permissions.  
+Roles `my.1.role`, `my.2.role`, `my.foo.role`, `my.bar.role`, etc. **cannot** produce and consume.

+Tenants, like namespaces, can be managed using the [admin API](admin-api-overview.md). There are currently two configurable aspects of tenants:
+
+* Admin roles
+* Allowed clusters
+
+## Tenant resources
+
+### List
+
+You can list all of the tenants associated with an [instance](reference-terminology.md#instance).
+
+````mdx-code-block
+<Tabs 
+  defaultValue="pulsar-admin"
+  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"JAVA","value":"JAVA"}]}>
+<TabItem value="pulsar-admin">
+
+Use the [`list`](reference-pulsar-admin.md#tenants-list) subcommand.

+
+### Create
+
+You can create a new tenant.
+
+````mdx-code-block

+
+Use the [`create`](reference-pulsar-admin.md#tenants-create) subcommand:
+
+```shell
+
+$ pulsar-admin tenants create my-tenant
+
+```
+
+When creating a tenant, you can optionally assign admin roles using the `-r`/`--admin-roles`
+flag, and clusters using the `-c`/`--allowed-clusters` flag. You can specify multiple values
+as a comma-separated list. Here are some examples:
+
+```shell
+
+$ pulsar-admin tenants create my-tenant \
+  --admin-roles role1,role2,role3 \
+  --allowed-clusters cluster1
+
+$ pulsar-admin tenants create my-tenant \
+  -r role1
+  -c cluster1
+
+```

+
+Pulsar has persistent and non-persistent topics. Persistent topic is a logical endpoint for publishing and consuming messages. The topic name structure for persistent topics is:
+
+```shell
+
+persistent://tenant/namespace/topic
+
+```
+
+Non-persistent topics are used in applications that only consume real-time published messages and do not need persistent guarantee. In this way, it reduces message-publish latency by removing overhead of persisting messages. The topic name structure for non-persistent topics is:
+
+```shell
+
+non-persistent://tenant/namespace/topic
+
+```
+
+## Manage topic resources
+Whether it is persistent or non-persistent topic, you can obtain the topic resources through `pulsar-admin` tool, REST API and Java.
+
+:::note
+
+In REST API, `:schema` stands for persistent or non-persistent. `:tenant`, `:namespace`, `:x` are variables, replace them with the real tenant, namespace, and `x` names when using them.     
+Take {@inject: endpoint|GET|/admin/v2/:schema/:tenant/:namespace|operation/getList?version=@pulsar:version_number@} as an example, to get the list of persistent topics in REST API, use `https://pulsar.apache.org/admin/v2/persistent/my-tenant/my-namespace`. To get the list of non-persistent topics in REST API, use `https://pulsar.apache.org/admin/v2/non-persistent/my-tenant/my-namespace`.

+## Manage non-partitioned topics
+You can use Pulsar [admin API](admin-api-overview.md) to create, delete and check status of non-partitioned topics.
+
+### Create
+Non-partitioned topics must be explicitly created. When creating a new non-partitioned topic, you need to provide a name for the topic.
+
+By default, 60 seconds after creation, topics are considered inactive and deleted automatically to avoid generating trash data. To disable this feature, set `brokerDeleteInactiveTopicsEnabled` to `false`. To change the frequency of checking inactive topics, set `brokerDeleteInactiveTopicsFrequencySeconds` to a specific value.
+
+For more information about the two parameters, see [here](reference-configuration.md#broker).
+
+You can create non-partitioned topics in the following ways.
+````mdx-code-block
+<Tabs 
+  defaultValue="pulsar-admin"
+  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
+<TabItem value="pulsar-admin">
+
+When you create non-partitioned topics with the [`create`](reference-pulsar-admin.md#create-3) command, you need to specify the topic name as an argument.
+
+```shell
+
+$ bin/pulsar-admin topics create \
+  persistent://my-tenant/my-namespace/my-topic
+
+```
+
+:::note
+
+When you create a non-partitioned topic with the suffix '-partition-' followed by numeric value like 'xyz-topic-partition-x' for the topic name, if a partitioned topic with same suffix 'xyz-topic-partition-y' exists, then the numeric value(x) for the non-partitioned topic must be larger than the number of partitions(y) of the partitioned topic. Otherwise, you cannot create such a non-partitioned topic.

+
+## Manage partitioned topics
+You can use Pulsar [admin API](admin-api-overview.md) to create, update, delete and check status of partitioned topics.
+
+### Create
+
+Partitioned topics must be explicitly created. When creating a new partitioned topic, you need to provide a name and the number of partitions for the topic.
+
+By default, 60 seconds after creation, topics are considered inactive and deleted automatically to avoid generating trash data. To disable this feature, set `brokerDeleteInactiveTopicsEnabled` to `false`. To change the frequency of checking inactive topics, set `brokerDeleteInactiveTopicsFrequencySeconds` to a specific value.
+
+For more information about the two parameters, see [here](reference-configuration.md#broker).
+
+You can create partitioned topics in the following ways.
+````mdx-code-block
+<Tabs

+  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
+<TabItem value="pulsar-admin">
+
+When you create partitioned topics with the [`create-partitioned-topic`](reference-pulsar-admin.md#create-partitioned-topic)
+command, you need to specify the topic name as an argument and the number of partitions using the `-p` or `--partitions` flag.
+
+```shell
+
+$ bin/pulsar-admin topics create-partitioned-topic \
+  persistent://my-tenant/my-namespace/my-topic \
+  --partitions 4
+
+```
+
+:::note
+
+If a non-partitioned topic with the suffix '-partition-' followed by a numeric value like 'xyz-topic-partition-10', you can not create a partitioned topic with name 'xyz-topic', because the partitions of the partitioned topic could override the existing non-partitioned topic. To create such partitioned topic, you have to delete that non-partitioned topic first.

+
+## Publish to partitioned topics
+
+By default, Pulsar topics are served by a single broker, which limits the maximum throughput of a topic. *Partitioned topics* can span multiple brokers and thus allow for higher throughput. 
+
+You can publish to partitioned topics using Pulsar client libraries. When publishing to partitioned topics, you must specify a routing mode. If you do not specify any routing mode when you create a new producer, the round robin routing mode is used. 
+
+### Routing mode
+
+You can specify the routing mode in the ProducerConfiguration object that you use to configure your producer. The routing mode determines which partition(internal topic) that each message should be published to.
+
+The following {@inject: javadoc:MessageRoutingMode:/client/org/apache/pulsar/client/api/MessageRoutingMode} options are available.
+
+Mode     | Description 
+:--------|:------------
+`RoundRobinPartition` | If no key is provided, the producer publishes messages across all partitions in round-robin policy to achieve the maximum throughput. Round-robin is not done per individual message, round-robin is set to the same boundary of batching delay to ensure that batching is effective. If a key is specified on the message, the partitioned producer hashes the key and assigns message to a particular partition. This is the default mode. 
+`SinglePartition`     | If no key is provided, the producer picks a single partition randomly and publishes all messages into that partition. If a key is specified on the message, the partitioned producer hashes the key and assigns message to a particular partition.
+`CustomPartition`     | Use custom message router implementation that is called to determine the partition for a particular message. You can create a custom routing mode by using the Java client and implementing the {@inject: javadoc:MessageRouter:/client/org/apache/pulsar/client/api/MessageRouter} interface.
+
+The following is an example:
+
+```java
+
+String pulsarBrokerRootUrl = "pulsar://localhost:6650";
+String topic = "persistent://my-tenant/my-namespace/my-topic";
+
+PulsarClient pulsarClient = PulsarClient.builder().serviceUrl(pulsarBrokerRootUrl).build();
+Producer<byte[]> producer = pulsarClient.newProducer()
+        .topic(topic)
+        .messageRoutingMode(MessageRoutingMode.SinglePartition)
+        .create();
+producer.send("Partitioned topic message".getBytes());
+
+```
+
+### Custom message router
+
+To use a custom message router, you need to provide an implementation of the {@inject: javadoc:MessageRouter:/client/org/apache/pulsar/client/api/MessageRouter} interface, which has just one `choosePartition` method:
+
+```java
+
+public interface MessageRouter extends Serializable {
+    int choosePartition(Message msg);
+}
+
+```
+
+The following router routes every message to partition 10:
+
+```java
+
+public class AlwaysTenRouter implements MessageRouter {
+    public int choosePartition(Message msg) {
+        return 10;
+    }
+}
+
+```
+
+With that implementation, you can send
+
+```java
+
+String pulsarBrokerRootUrl = "pulsar://localhost:6650";
+String topic = "persistent://my-tenant/my-cluster-my-namespace/my-topic";
+
+PulsarClient pulsarClient = PulsarClient.builder().serviceUrl(pulsarBrokerRootUrl).build();
+Producer<byte[]> producer = pulsarClient.newProducer()
+        .topic(topic)
+        .messageRouter(new AlwaysTenRouter())
+        .create();
+producer.send("Partitioned topic message".getBytes());
+
+```
+
+### How to choose partitions when using a key
+If a message has a key, it supersedes the round robin routing policy. The following example illustrates how to choose the partition when using a key.
+
+```java
+
+// If the message has a key, it supersedes the round robin routing policy
+        if (msg.hasKey()) {
+            return signSafeMod(hash.makeHash(msg.getKey()), topicMetadata.numPartitions());
+        }
+
+        if (isBatchingEnabled) { // if batching is enabled, choose partition on `partitionSwitchMs` boundary.
+            long currentMs = clock.millis();
+            return signSafeMod(currentMs / partitionSwitchMs + startPtnIdx, topicMetadata.numPartitions());
+        } else {
+            return signSafeMod(PARTITION_INDEX_UPDATER.getAndIncrement(this), topicMetadata.numPartitions());
+        }
+
+```
+
+## Manage subscriptions
+
+You can use [Pulsar admin API](admin-api-overview.md) to create, check, and delete subscriptions.
+
+### Create subscription

+## Enable geo-replication for a namespace
+
+You must enable geo-replication on a [per-tenant basis](#concepts-multi-tenancy) in Pulsar. For example, you can enable geo-replication between two specific clusters only when a tenant has access to both clusters.
+
+Geo-replication is managed at the namespace level, which means you only need to create and configure a namespace to replicate messages between two or more provisioned clusters that a tenant can access.
+
+Complete the following tasks to enable geo-replication for a namespace:
+
+* [Enable a geo-replication namespace](#enable-geo-replication-at-namespace-level)
+* [Configure that namespace to replicate across two or more provisioned clusters](admin-api-namespaces.md/#configure-replication-clusters)
+
+Any message published on *any* topic in that namespace is replicated to all clusters in the specified set.
+
+## Local persistence and forwarding
+
+When messages are produced on a Pulsar topic, messages are first persisted in the local cluster, and then forwarded asynchronously to the remote clusters.
+
+In normal cases, when connectivity issues are none, messages are replicated immediately, at the same time as they are dispatched to local consumers. Typically, the network [round-trip time](https://en.wikipedia.org/wiki/Round-trip_delay_time) (RTT) between the remote regions defines end-to-end delivery latency.
+
+Applications can create producers and consumers in any of the clusters, even when the remote clusters are not reachable (like during a network partition).
+
+Producers and consumers can publish messages to and consume messages from any cluster in a Pulsar instance. However, subscriptions cannot only be local to the cluster where the subscriptions are created but also can be transferred between clusters after replicated subscription is enabled. Once replicated subscription is enabled, you can keep subscription state in synchronization. Therefore, a topic can be asynchronously replicated across multiple geographical regions. In case of failover [...]
+
+![A typical geo-replication example with full-mesh pattern](/assets/geo-replication.png)
+
+In the aforementioned example, the **T1** topic is replicated among three clusters, **Cluster-A**, **Cluster-B**, and **Cluster-C**.
+
+All messages produced in any of the three clusters are delivered to all subscriptions in other clusters. In this case, **C1** and **C2** consumers receive all messages that **P1**, **P2**, and **P3** producers publish. Ordering is still guaranteed on a per-producer basis.
+
+## Configure replication
+
+This section guides you through the steps to configure geo-replicated clusters.
+1. [Connect replication clusters](#connect-replication-clusters)
+2. [Grant permissions to properties](#grant-permissions-to-properties)
+3. [Enable geo-replication](#enable-geo-replication)
+4. [Use topics with geo-replication](#use-topics-with-geo-replication)
+
+### Connect replication clusters
+
+To replicate data among clusters, you need to configure each cluster to connect to the other. You can use the [`pulsar-admin`](https://pulsar.apache.org/tools/pulsar-admin/) tool to create a connection.
+
+**Example**
+
+Suppose that you have 3 replication clusters: `us-west`, `us-cent`, and `us-east`.
+
+1. Configure the connection from `us-west` to `us-east`.
+
+   Run the following command on `us-west`.
+
+```shell
+
+$ bin/pulsar-admin clusters create \
+  --broker-url pulsar://<DNS-OF-US-EAST>:<PORT>	\
+  --url http://<DNS-OF-US-EAST>:<PORT> \
+  us-east
+
+```
+
+   :::tip
+
+   - If you want to use a secure connection for a cluster, you can use the flags `--broker-url-secure` and `--url-secure`. For more information, see [pulsar-admin clusters create](https://pulsar.apache.org/tools/pulsar-admin/).
+   - Different clusters may have different authentications. You can use the authentication flag `--auth-plugin` and `--auth-parameters` together to set cluster authentication, which overrides `brokerClientAuthenticationPlugin` and `brokerClientAuthenticationParameters` if `authenticationEnabled` sets to `true` in `broker.conf` and `standalone.conf`. For more information, see [authentication and authorization](concepts-authentication.md).
+
+   :::
+
+2. Configure the connection from `us-west` to `us-cent`.
+
+   Run the following command on `us-west`.
+
+```shell
+
+$ bin/pulsar-admin clusters create \
+  --broker-url pulsar://<DNS-OF-US-CENT>:<PORT>	\
+  --url http://<DNS-OF-US-CENT>:<PORT> \
+  us-cent
+
+```
+
+3. Run similar commands on `us-east` and `us-cent` to create connections among clusters.
+
+### Grant permissions to properties
+
+To replicate to a cluster, the tenant needs permission to use that cluster. You can grant permission to the tenant when you create the tenant or grant later.
+
+Specify all the intended clusters when you create a tenant:
+
+```shell
+
+$ bin/pulsar-admin tenants create my-tenant \
+  --admin-roles my-admin-role \
+  --allowed-clusters us-west,us-east,us-cent
+
+```
+
+To update permissions of an existing tenant, use `update` instead of `create`.
+
+### Enable geo-replication 
+
+You can enable geo-replication at **namespace** or **topic** level.
+
+#### Enable geo-replication at namespace level
+
+You can create a namespace with the following command sample.
+
+```shell
+
+$ bin/pulsar-admin namespaces create my-tenant/my-namespace
+
+```
+
+Initially, the namespace is not assigned to any cluster. You can assign the namespace to clusters using the `set-clusters` subcommand:
+
+```shell
+
+$ bin/pulsar-admin namespaces set-clusters my-tenant/my-namespace \
+  --clusters us-west,us-east,us-cent
+
+```
+
+#### Enable geo-replication at topic level
+
+You can set geo-replication at topic level using the command `pulsar-admin topics set-replication-clusters`. For the latest and complete information about `Pulsar admin`, including commands, flags, descriptions, and more information, see [Pulsar admin doc](https://pulsar.apache.org/tools/pulsar-admin/).
+
+```shell
+
+$ bin/pulsar-admin topics set-replication-clusters --clusters us-west,us-east,us-cent my-tenant/my-namespace/my-topic
+
+```
+
+:::tip
+
+- You can change the replication clusters for a namespace at any time, without disruption to ongoing traffic. Replication channels are immediately set up or stopped in all clusters as soon as the configuration changes.
+- Once you create a geo-replication namespace, any topics that producers or consumers create within that namespace are replicated across clusters. Typically, each application uses the `serviceUrl` for the local cluster.
+- If you are using Pulsar version `2.10.x`, to enable geo-replication at topic level, you need to change the following configurations in the `conf/broker.conf` or `conf/standalone.conf` file to enable topic policies service.
+```shell
+systemTopicEnabled=true
+topicLevelPoliciesEnabled=true
+```
+:::
+
+### Use topics with geo-replication
+
+#### Selective replication
+
+By default, messages are replicated to all clusters configured for the namespace. You can restrict replication selectively by specifying a replication list for a message, and then that message is replicated only to the subset in the replication list.
+
+The following is an example for the [Java API](client-libraries-java.md). Note the use of the `setReplicationClusters` method when you construct the {@inject: javadoc:Message:/client/org/apache/pulsar/client/api/Message} object:
+
+```java
+
+List<String> restrictReplicationTo = Arrays.asList(
+        "us-west",
+        "us-east"
+);
+
+Producer producer = client.newProducer()
+        .topic("some-topic")
+        .create();
+
+producer.newMessage()
+        .value("my-payload".getBytes())
+        .setReplicationClusters(restrictReplicationTo)
+        .send();
+
+```
+
+#### Topic stats
+
+You can check topic-specific statistics for geo-replication topics using one of the following methods.
+
+````mdx-code-block
+<Tabs 
+  defaultValue="pulsar-admin"
+  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"}]}>
+<TabItem value="pulsar-admin">
+
+Use the [`pulsar-admin topics stats`](https://pulsar.apache.org/tools/pulsar-admin/) command.
+
+```shell
+
+$ bin/pulsar-admin topics stats persistent://my-tenant/my-namespace/my-topic
+
+```
+
+</TabItem>
+<TabItem value="REST API">
+
+{@inject: endpoint|GET|/admin/v2/:schema/:tenant/:namespace/:topic/stats|operation/getStats?version=@pulsar:version_number@}
+
+</TabItem>
+
+</Tabs>
+````
+
+Each cluster reports its own local stats, including the incoming and outgoing replication rates and backlogs.
+
+#### Delete a geo-replication topic
+
+Given that geo-replication topics exist in multiple regions, directly deleting a geo-replication topic is not possible. Instead, you should rely on automatic topic garbage collection.
+
+In Pulsar, a topic is automatically deleted when the topic meets the following three conditions:
+- no producers or consumers are connected to it;
+- no subscriptions to it;
+- no more messages are kept for retention. 
+For geo-replication topics, each region uses a fault-tolerant mechanism to decide when deleting the topic locally is safe.
+
+You can explicitly disable topic garbage collection by setting `brokerDeleteInactiveTopicsEnabled` to `false` in your [broker configuration](reference-configuration.md#broker).
+
+To delete a geo-replication topic, close all producers and consumers on the topic, and delete all of its local subscriptions in every replication cluster. When Pulsar determines that no valid subscription for the topic remains across the system, it will garbage collect the topic.
+
+## Replicated subscriptions
+
+Pulsar supports replicated subscriptions, so you can keep subscription state in sync, within a sub-second timeframe, in the context of a topic that is being asynchronously replicated across multiple geographical regions.
+
+In case of failover, a consumer can restart consuming from the failure point in a different cluster. 
+
+### Enable replicated subscription
+
+Replicated subscription is disabled by default. You can enable replicated subscription when creating a consumer. 
+
+```java
+
+Consumer<String> consumer = client.newConsumer(Schema.STRING)
+            .topic("my-topic")
+            .subscriptionName("my-subscription")
+            .replicateSubscriptionState(true)
+            .subscribe();
+
+```
+
+### Advantages
+
+ * It is easy to implement the logic. 
+ * You can choose to enable or disable replicated subscription.
+ * When you enable it, the overhead is low, and it is easy to configure. 
+ * When you disable it, the overhead is zero.
+
+### Limitations
+
+* When you enable replicated subscription, you're creating a consistent distributed snapshot to establish an association between message ids from different clusters. The snapshots are taken periodically. The default value is `1 second`. It means that a consumer failing over to a different cluster can potentially receive 1 second of duplicates. You can also configure the frequency of the snapshot in the `broker.conf` file.
+* Only the base line cursor position is synced in replicated subscriptions while the individual acknowledgments are not synced. This means the messages acknowledged out-of-order could end up getting delivered again, in the case of a cluster failover.
+
+## Migrate data between clusters using geo-replication
+
+Using geo-replication to migrate data between clusters is a special use case of the [active-active replication pattern](concepts-replication.md/#active-active-replication) when you don't have a large amount of data.
+
+1. Create your new cluster.
+2. Add the new cluster to your old cluster.
+
+```shell
+
+  bin/pulsar-admin cluster create new-cluster
+
+```
+
+3. Add the new cluster to your tenant.
+
+```shell
+
+  bin/pulsar-admin tenants update my-tenant --cluster old-cluster,new-cluster
+
+```
+
+4. Set the clusters on your namespace.
+
+```shell
+
+  bin/pulsar-admin namespaces set-clusters my-tenant/my-ns --cluster old-cluster,new-cluster
+
+```
+
+5. Update your applications using [replicated subscriptions](#replicated-subscriptions).
+6. Validate subscription replication is active.
+
+```shell
+
+  bin/pulsar-admin topics stats-internal public/default/t1
+
+```
+
+7. Move your consumers and producers to the new cluster by modifying the values of `serviceURL`.
+
+:::note
+
+* The replication starts from step 4, which means existing messages in your old cluster are not replicated. 
+* If you have some older messages to migrate, you can pre-create the replication subscriptions for each topic and set it at the earliest position by using `pulsar-admin topics create-subscription -s pulsar.repl.new-cluster -m earliest <topic>`.

+
+
+In an organization, a Pulsar instance provides services to multiple teams. When organizing the resources across multiple teams, you want to make a suitable isolation plan to avoid the resource competition between different teams and applications and provide high-quality messaging service. In this case, you need to take resource isolation into consideration and weigh your intended actions against expected and unexpected consequences.
+
+To enforce resource isolation, you can use the Pulsar isolation policy, which allows you to allocate resources (**broker** and **bookie**) for the namespace.
+
+## Broker isolation
+
+In Pulsar, when namespaces (more specifically, namespace bundles) are assigned dynamically to brokers, the namespace isolation policy limits the set of brokers that can be used for assignment. Before topics are assigned to brokers, you can set the namespace isolation policy with a primary or a secondary regex to select desired brokers.
+
+You can set a namespace isolation policy for a cluster using one of the following methods.

+title: Load balance across brokers
+sidebar_label: "Load balance"
+original_id: administration-load-balance
+---
+
+
+Pulsar is a horizontally scalable messaging system, so the traffic in a logical cluster must be balanced across all the available Pulsar brokers as evenly as possible, which is a core requirement.
+
+You can use multiple settings and tools to control the traffic distribution which requires a bit of context to understand how the traffic is managed in Pulsar. Though in most cases, the core requirement mentioned above is true out of the box and you should not worry about it. 
+
+The following sections introduce how the load-balanced assignments work across Pulsar brokers and how you can leverage the framework to adjust.
+
+## Dynamic assignments
+
+Topics are dynamically assigned to brokers based on the load conditions of all brokers in the cluster. The assignment of topics to brokers is not done at the topic level but at the **bundle** level (a higher level). Instead of individual topic assignments, each broker takes ownership of a subset of the topics for a namespace. This subset is called a bundle and effectively this subset is a sharding mechanism. 
+
+In other words, each namespace is an "administrative" unit and sharded into a list of bundles, with each bundle comprising a portion of the overall hash range of the namespace. Topics are assigned to a particular bundle by taking the hash of the topic name and checking in which bundle the hash falls. Each bundle is independent of the others and thus is independently assigned to different brokers.
+
+The benefit of the assignment granularity is to amortize the amount of information that you need to keep track of. Based on CPU, memory, traffic load, and other indexes, topics are assigned to a particular broker dynamically. For example: 
+* When a client starts using new topics that are not assigned to any broker, a process is triggered to choose the best-suited broker to acquire ownership of these topics according to the load conditions. 
+* If the broker owning a topic becomes overloaded, the topic is reassigned to a less-loaded broker.
+* If the broker owning a topic crashes, the topic is reassigned to another active broker.
+
+:::tip
+
+For partitioned topics, different partitions are assigned to different brokers. Here "topic" means either a non-partitioned topic or one partition of a topic.
+
+:::
+
+## Create namespaces with assigned bundles
+
+When you create a new namespace, a number of bundles are assigned to the namespace. You can set this number in the `conf/broker.conf` file:
+
+```conf
+
+# When a namespace is created without specifying the number of bundles, this
+# value will be used as the default
+defaultNumberOfNamespaceBundles=4
+
+```
+
+Alternatively, you can override the value when you create a new namespace using [Pulsar admin](/tools/pulsar-admin/):
+
+```shell
+
+bin/pulsar-admin namespaces create my-tenant/my-namespace --clusters us-west --bundles 16
+
+```
+
+With the above command, you create a namespace with 16 initial bundles. Therefore the topics for this namespace can immediately be spread across up to 16 brokers.
+
+In general, if you know the expected traffic and number of topics in advance, you had better start with a reasonable number of bundles instead of waiting for the system to auto-correct the distribution.
+
+On the same note, it is beneficial to start with more bundles than the number of brokers, due to the hashing nature of the distribution of topics into bundles. For example, for a namespace with 1000 topics, using something like 64 bundles achieves a good distribution of traffic across 16 brokers.
+
+
+## Split namespace bundles
+
+Since the load for the topics in a bundle might change over time and predicting the load might be hard, bundle split is designed to resolve these challenges. The broker splits a bundle into two and the new smaller bundles can be reassigned to different brokers.
+
+Pulsar supports the following two bundle split algorithms:
+* `range_equally_divide`: split the bundle into two parts with the same hash range size.
+* `topic_count_equally_divide`: split the bundle into two parts with the same number of topics.
+
+To enable bundle split, you need to configure the following settings in the `broker.conf` file, and set `defaultNamespaceBundleSplitAlgorithm` based on your needs.
+
+```conf
+
+loadBalancerAutoBundleSplitEnabled=true
+loadBalancerAutoUnloadSplitBundlesEnabled=true
+defaultNamespaceBundleSplitAlgorithm=range_equally_divide
+
+```
+
+You can configure more parameters for splitting thresholds. Any existing bundle that exceeds any of the thresholds is a candidate to be split. By default, the newly split bundles are immediately reassigned to other brokers, to facilitate the traffic distribution. 
+
+```conf
+
+# maximum topics in a bundle, otherwise bundle split will be triggered
+loadBalancerNamespaceBundleMaxTopics=1000
+
+# maximum sessions (producers + consumers) in a bundle, otherwise bundle split will be triggered
+loadBalancerNamespaceBundleMaxSessions=1000
+
+# maximum msgRate (in + out) in a bundle, otherwise bundle split will be triggered
+loadBalancerNamespaceBundleMaxMsgRate=30000
+
+# maximum bandwidth (in + out) in a bundle, otherwise bundle split will be triggered
+loadBalancerNamespaceBundleMaxBandwidthMbytes=100
+
+# maximum number of bundles in a namespace (for auto-split)
+loadBalancerNamespaceMaximumBundles=128
+
+```
+
+## Shed load automatically
+
+The support for automatic load shedding is available in the load manager of Pulsar. This means that whenever the system recognizes a particular broker is overloaded, the system forces some traffic to be reassigned to less-loaded brokers.
+
+When a broker is identified as overloaded, the broker forces to "unload" a subset of the bundles, the ones with higher traffic, that make up for the overload percentage.
+
+For example, the default threshold is 85% and if a broker is over quota at 95% CPU usage, then the broker unloads the percent difference plus a 5% margin: `(95% - 85%) + 5% = 15%`. Given the selection of bundles to unload is based on traffic (as a proxy measure for CPU, network, and memory), the broker unloads bundles for at least 15% of traffic.
+
+:::tip
+
+* The automatic load shedding is enabled by default. To disable it, you can set `loadBalancerSheddingEnabled` to `false`.
+* Besides the automatic load shedding, you can [manually unload bundles](#unload-topics-and-bundles).
+
+:::
+
+Additional settings that apply to shedding:
+
+```conf
+
+# Load shedding interval. Broker periodically checks whether some traffic should be offload from
+# some over-loaded broker to other under-loaded brokers
+loadBalancerSheddingIntervalMinutes=1
+
+# Prevent the same topics to be shed and moved to other brokers more than once within this timeframe
+loadBalancerSheddingGracePeriodMinutes=30
+
+```
+
+Pulsar supports the following types of automatic load shedding strategies. 
+* [ThresholdShedder](#thresholdshedder)
+* [OverloadShedder](#overloadshedder)
+* [UniformLoadShedder](#uniformloadshedder)
+
+:::note
+
+* From Pulsar 2.10, the **default** shedding strategy is `ThresholdShedder`.
+* You need to restart brokers if the shedding strategy is [dynamically updated](admin-api-brokers.md/#dynamic-broker-configuration). 
+
+:::
+
+### ThresholdShedder
+This strategy tends to shed the bundles if any broker's usage is above the configured threshold. It does this by first computing the average resource usage per broker for the whole cluster. The resource usage for each broker is calculated using the following method `LocalBrokerData#getMaxResourceUsageWithWeight`. Historical observations are included in the running average based on the broker's setting for `loadBalancerHistoryResourcePercentage`. Once the average resource usage is calcula [...]
+
+![Shedding strategy - ThresholdShedder](/assets/shedding-strategy-thresholdshedder.svg)
+
+For example, assume you have three brokers, the average broker usage of broker1 is 40%, the average broker usage of broker2 and broker3 is 10%, then the cluster average usage is 20% ((40% + 10% + 10%) / 3). If you set `loadBalancerBrokerThresholdShedderPercentage` to `10`, then only broker1's certain bundles get unloaded, because the average usage of broker1 is greater than the sum of the cluster average usage (20%) plus `loadBalancerBrokerThresholdShedderPercentage`(10%).
+
+To use the `ThresholdShedder` strategy, configure brokers with this value.
+`loadBalancerLoadSheddingStrategy=org.apache.pulsar.broker.loadbalance.impl.ThresholdShedder`
+
+You can configure the weights for each resource per broker in the `conf/broker.conf` file. 
+

+### OverloadShedder
+This strategy attempts to shed exactly one bundle on brokers which are overloaded, that is, whose maximum system resource usage exceeds [`loadBalancerBrokerOverloadedThresholdPercentage`](#broker-overload-thresholds). To see which resources are considered when determining the maximum system resource. A bundle is recommended for unloading off that broker if and only if the following conditions hold: The broker has at least two bundles assigned and the broker has at least one bundle that h [...]
+
+![Shedding strategy - OverloadShedder](/assets/shedding-strategy-overloadshedder.svg)
+
+To use the `OverloadShedder` strategy, configure brokers with this value.
+`loadBalancerLoadSheddingStrategy=org.apache.pulsar.broker.loadbalance.impl.OverloadShedder`
+
+#### Broker overload thresholds
+
+The determination of when a broker is overloaded is based on the threshold of CPU, network, and memory usage. Whenever either of those metrics reaches the threshold, the system triggers the shedding (if enabled).
+
+:::note
+
+The overload threshold `loadBalancerBrokerOverloadedThresholdPercentage` only applies to the [`OverloadShedder`](#overloadshedder) shedding strategy. By default, it is set to 85%.
+
+:::
+
+Pulsar gathers the CPU, network, and memory usage stats from the system metrics. In some cases of network utilization, the network interface speed that Linux reports is not correct and needs to be manually overridden. This is the case in AWS EC2 instances with 1Gbps NIC speed for which the OS reports 10Gbps speed.
+
+Because of the incorrect max speed, the load manager might think the broker has not reached the NIC capacity, while in fact the broker already uses all the bandwidth and the traffic is slowed down.
+
+You can set `loadBalancerOverrideBrokerNicSpeedGbps` in the `conf/broker.conf` file to correct the max NIC speed. When the value is empty, Pulsar uses the value that the OS reports.
+
+### UniformLoadShedder
+This strategy tends to distribute load uniformly across all brokers. This strategy checks the load difference between the broker with the highest load and the broker with the lowest load. If the difference is higher than configured thresholds `loadBalancerMsgRateDifferenceShedderThreshold` and `loadBalancerMsgThroughputMultiplierDifferenceShedderThreshold` then it finds out bundles that can be unloaded to distribute traffic evenly across all brokers. 
+
+![Shedding strategy - UniformLoadShedder](/assets/shedding-strategy-uniformLoadshedder.svg)
+
+To use the `UniformLoadShedder` strategy, configure brokers with this value.
+`loadBalancerLoadSheddingStrategy=org.apache.pulsar.broker.loadbalance.impl.UniformLoadShedder`
+
+## Unload topics and bundles
+
+You can "unload" a topic in Pulsar manual admin operations. Unloading means closing topics, releasing ownership, and reassigning topics to a new broker, based on the current load.
+
+When unloading happens, the client experiences a small latency blip, typically in the order of tens of milliseconds, while the topic is reassigned.
+
+Unloading is the mechanism that the load manager uses to perform the load shedding, but you can also trigger the unloading manually, for example, to correct the assignments and redistribute traffic even before having any broker overloaded.
+
+Unloading a topic has no effect on the assignment, but just closes and reopens the particular topic:
+
+```shell
+
+pulsar-admin topics unload persistent://tenant/namespace/topic
+
+```
+
+To unload all topics for a namespace and trigger reassignments:
+
+```shell
+
+pulsar-admin namespaces unload tenant/namespace
+
+```
+
+## Distribute anti-affinity namespaces across failure domains
+
+When your application has multiple namespaces and you want one of them available all the time to avoid any downtime, you can group these namespaces and distribute them across different [failure domains](reference-terminology.md#failure-domain) and different brokers. Thus, if one of the failure domains is down (due to release rollout or brokers restart), it only disrupts namespaces owned by that specific failure domain and the rest of the namespaces owned by other domains remain available [...]
+
+Such a group of namespaces has anti-affinity to each other, that is, all the namespaces in this group are [anti-affinity namespaces](reference-terminology.md#anti-affinity-namespaces) and are distributed to different failure domains in a load-balanced manner. 
+
+As illustrated in the following figure, Pulsar has 2 failure domains (Domain1 and Domain2) and each domain has 2 brokers in it. You can create an anti-affinity namespace group that has 4 namespaces in it, and all the 4 namespaces have anti-affinity to each other. The load manager tries to distribute namespaces evenly across all the brokers in the same domain. Since each domain has 2 brokers, every broker owns one namespace from this anti-affinity namespace group, and you can see each dom [...]
+
+![Distribute anti-affinity namespaces across failure domains](/assets/anti-affinity-namespaces-across-failure-domains.svg)
+
+The load manager follows an even distribution policy across failure domains to assign anti-affinity namespaces. The following table outlines the even-distributed assignment sequence illustrated in the above figure.
+
+| Assignment sequence | Namespace | Failure domain candidates | Broker candidates | Selected broker |
+|:---|:------------|:------------------|:------------------------------------|:-----------------|
+| 1 | Namespace1 | Domain1, Domain2 | Broker1, Broker2, Broker3, Broker4 | Domain1:Broker1 |
+| 2 | Namespace2 | Domain2          | Broker3, Broker4                   | Domain2:Broker3 |
+| 3 | Namespace3 | Domain1, Domain2 | Broker2, Broker4                   | Domain1:Broker2 |
+| 4 | Namespace4 | Domain2          | Broker4                            | Domain2:Broker4 |
+ 
+:::tip
+
+* Each namespace belongs to only one anti-affinity group. If a namespace with an existing anti-affinity assignment is assigned to another anti-affinity group, the original assignment is dropped.
+
+* If there are more anti-affinity namespaces than failure domains, the load manager distributes namespaces evenly across all the domains, and also every domain distributes namespaces evenly across all the brokers under that domain.
+
+:::
+
+### Create a failure domain and register brokers
+ 
+:::note
+
+One broker can only be registered to a single failure domain.
+
+:::
+ 
+To create a domain under a specific cluster and register brokers, run the following command:
+
+```bash
+
+pulsar-admin clusters create-failure-domain <cluster-name> --domain-name <domain-name> --broker-list <broker-list-comma-separated>
+
+```
+
+You can also view, update, and delete domains under a specific cluster. For more information, refer to [Pulsar admin doc](/tools/pulsar-admin/).
+
+### Create an anti-affinity namespace group
+
+An anti-affinity group is created automatically when the first namespace is assigned to the group. To assign a namespace to an anti-affinity group, run the following command. It sets an anti-affinity group name for a namespace.
+ 
+```bash
+
+pulsar-admin namespaces set-anti-affinity-group <namespace> --group <group-name>
+ 
+```
+
+For more information about `anti-affinity-group` related commands, refer to [Pulsar admin doc](/tools/pulsar-admin/).

+title: Pulsar proxy
+sidebar_label: "Pulsar proxy"
+original_id: administration-proxy
+---
+
+Pulsar proxy is an optional gateway. Pulsar proxy is used when direct connections between clients and Pulsar brokers are either infeasible or undesirable. For example, when you run Pulsar in a cloud environment or on [Kubernetes](https://kubernetes.io) or an analogous platform, you can run Pulsar proxy.
+
+## Configure the proxy
+
+Before using the proxy, you need to configure it with the brokers addresses in the cluster. You can configure the broker URL in the proxy configuration, or the proxy to connect directly using service discovery.
+
+> In a production environment service discovery is not recommended.
+
+### Use broker URLs
+
+It is more secure to specify a URL to connect to the brokers.
+
+Proxy authorization requires access to ZooKeeper, so if you use these broker URLs to connect to the brokers, you need to disable authorization at the Proxy level. Brokers still authorize requests after the proxy forwards them.
+
+You can configure the broker URLs in `conf/proxy.conf` as follows.
+
+```properties
+
+brokerServiceURL=pulsar://brokers.example.com:6650
+brokerWebServiceURL=http://brokers.example.com:8080
+functionWorkerWebServiceURL=http://function-workers.example.com:8080
+
+```
+
+If you use TLS, configure the broker URLs in the following way:
+
+```properties
+
+brokerServiceURLTLS=pulsar+ssl://brokers.example.com:6651
+brokerWebServiceURLTLS=https://brokers.example.com:8443
+functionWorkerWebServiceURL=https://function-workers.example.com:8443
+
+```
+
+The hostname in the URLs provided should be a DNS entry which points to multiple brokers or a virtual IP address, which is backed by multiple broker IP addresses, so that the proxy does not lose connectivity to Pulsar cluster if a single broker becomes unavailable.
+
+The ports to connect to the brokers (6650 and 8080, or in the case of TLS, 6651 and 8443) should be open in the network ACLs.
+
+Note that if you do not use functions, you do not need to configure `functionWorkerWebServiceURL`.
+
+### Use service discovery
+
+Pulsar uses [ZooKeeper](https://zookeeper.apache.org) for service discovery. To connect the proxy to ZooKeeper, specify the following in `conf/proxy.conf`.
+
+```properties
+
+metadataStoreUrl=my-zk-0:2181,my-zk-1:2181,my-zk-2:2181
+configurationMetadataStoreUrl=my-zk-0:2184,my-zk-remote:2184
+
+```
+
+> To use service discovery, you need to open the network ACLs, so the proxy can connects to the ZooKeeper nodes through the ZooKeeper client port (port `2181`) and the configuration store client port (port `2184`).
+
+> However, it is not secure to use service discovery. Because if the network ACL is open, when someone compromises a proxy, they have full access to ZooKeeper. 
+
+## Start the proxy
+
+To start the proxy:
+
+```bash
+
+$ cd /path/to/pulsar/directory
+$ bin/pulsar proxy \
+  --metadata-store zk:my-zk-1:2181,my-zk-2:2181,my-zk-3:2181 \
+  --configuration-metadata-store zk:my-zk-1:2181,my-zk-2:2181,my-zk-3:2181
+
+```
+
+> You can run multiple instances of the Pulsar proxy in a cluster.
+
+## Stop the proxy
+
+Pulsar proxy runs in the foreground by default. To stop the proxy, simply stop the process in which the proxy is running.
+
+## Proxy frontends
+
+You can run Pulsar proxy behind some kind of load-distributing frontend, such as an [HAProxy](https://www.digitalocean.com/community/tutorials/an-introduction-to-haproxy-and-load-balancing-concepts) load balancer.
+
+## Use Pulsar clients with the proxy
+
+Once your Pulsar proxy is up and running, preferably behind a load-distributing [frontend](#proxy-frontends), clients can connect to the proxy via whichever address that the frontend uses. If the address is the DNS address `pulsar.cluster.default`, for example, the connection URL for clients is `pulsar://pulsar.cluster.default:6650`.
+
+For more information on Proxy configuration, refer to [Pulsar proxy](reference-configuration.md#pulsar-proxy).

+
+Pulsar Manager is a web-based GUI management and monitoring tool that helps administrators and users manage and monitor tenants, namespaces, topics, subscriptions, brokers, clusters, and so on, and supports dynamic configuration of multiple environments.
+
+:::note
+
+If you are monitoring your current stats with [Pulsar dashboard](administration-dashboard.md), we recommend you use Pulsar Manager instead. Pulsar dashboard is deprecated.
+
+:::
+
+## Install
+
+### Quick Install
+The easiest way to use the Pulsar Manager is to run it inside a [Docker](https://www.docker.com/products/docker) container.
+
+```shell
+
+docker pull apachepulsar/pulsar-manager:v0.2.0
+docker run -it \
+    -p 9527:9527 -p 7750:7750 \
+    -e SPRING_CONFIGURATION_FILE=/pulsar-manager/pulsar-manager/application.properties \
+    apachepulsar/pulsar-manager:v0.2.0
+
+```
+
+* Pulsar Manager is divided into front-end and back-end, the front-end service port is `9527` and the back-end service port is `7750`.
+* `SPRING_CONFIGURATION_FILE`: Default configuration file for spring.
+* By default, Pulsar Manager uses the `herddb` database. HerdDB is a SQL distributed database implemented in Java and can be found at [herddb.org](https://herddb.org/) for more information.
+
+### Configure Database or JWT authentication
+####  Configure Database (optional)
+
+If you have a large amount of data, you can use a custom database. Otherwise, some display errors may occur. For example, the topic information cannot be displayed when the topic exceeds 10000.
+The following is an example of PostgreSQL.
+
+1. Initialize database and table structures using the [file](https://github.com/apache/pulsar-manager/blob/master/src/main/resources/META-INF/sql/postgresql-schema.sql).
+2. Download and modify the [configuration file](https://github.com/apache/pulsar-manager/blob/master/src/main/resources/application.properties), then add the PostgreSQL configuration.
+
+```properties
+
+spring.datasource.driver-class-name=org.postgresql.Driver
+spring.datasource.url=jdbc:postgresql://127.0.0.1:5432/pulsar_manager
+spring.datasource.username=postgres
+spring.datasource.password=postgres
+
+```
+
+3. Add a configuration mount and start with a docker image.
+
+```bash
+
+docker pull apachepulsar/pulsar-manager:v0.2.0
+docker run -it \
+    -p 9527:9527 -p 7750:7750 \
+    -v /your-path/application.properties:/pulsar-manager/pulsar-
+manager/application.properties
+    -e SPRING_CONFIGURATION_FILE=/pulsar-manager/pulsar-manager/application.properties \
+    apachepulsar/pulsar-manager:v0.2.0
+
+```
+
+####  Enable JWT authentication (optional)
+
+If you want to turn on JWT authentication, configure the `application.properties` file.
+
+```properties
+
+backend.jwt.token=token
+
+jwt.broker.token.mode=PRIVATE
+jwt.broker.public.key=file:///path/broker-public.key
+jwt.broker.private.key=file:///path/broker-private.key
+
+or 
+jwt.broker.token.mode=SECRET
+jwt.broker.secret.key=file:///path/broker-secret.key
+
+```
+
+•	`backend.jwt.token`: token for the superuser. You need to configure this parameter during cluster initialization.   
+•	`jwt.broker.token.mode`: multiple modes of generating token, including PUBLIC, PRIVATE, and SECRET.  
+•	`jwt.broker.public.key`: configure this option if you use the PUBLIC mode.  
+•	`jwt.broker.private.key`: configure this option if you use the PRIVATE mode.  
+•	`jwt.broker.secret.key`: configure this option if you use the SECRET mode.  
+For more information, see [Token Authentication Admin of Pulsar](security-token-admin.md).
+
+Docker command to add profile and key files mount.
+
+```bash
+
+docker pull apachepulsar/pulsar-manager:v0.2.0
+docker run -it \
+    -p 9527:9527 -p 7750:7750 \
+    -v /your-path/application.properties:/pulsar-manager/pulsar-
+manager/application.properties
+    -v /your-path/private.key:/pulsar-manager/private.key
+    -e SPRING_CONFIGURATION_FILE=/pulsar-manager/pulsar-manager/application.properties \
+    apachepulsar/pulsar-manager:v0.2.0
+
+```
+
+### Set the administrator account and password
+
+```bash
+
+CSRF_TOKEN=$(curl http://localhost:7750/pulsar-manager/csrf-token)
+curl \
+   -H 'X-XSRF-TOKEN: $CSRF_TOKEN' \
+   -H 'Cookie: XSRF-TOKEN=$CSRF_TOKEN;' \
+   -H "Content-Type: application/json" \
+   -X PUT http://localhost:7750/pulsar-manager/users/superuser \
+   -d '{"name": "admin", "password": "apachepulsar", "description": "test", "email": "username@test.org"}'
+
+```
+
+The request parameter in curl command:
+
+```json
+
+{"name": "admin", "password": "apachepulsar", "description": "test", "email": "username@test.org"}
+
+```
+
+- `name` is the Pulsar Manager login username, currently `admin`.
+- `password` is the password of the current user of Pulsar Manager, currently `apachepulsar`. The password should be more than or equal to 6 digits.
+
+
+
+### Configure the environment
+1. Login to the system, Visit http://localhost:9527 to login. The current default account is  `admin/apachepulsar`
+
+2. Click "New Environment" button to add an environment.
+
+3. Input the "Environment Name". The environment name is used for identifying an environment.
+
+4. Input the "Service URL". The Service URL is the admin service url of your Pulsar cluster.
+
+
+## Other Installation
+### Bare-metal installation
+
+When using binary packages for direct deployment, you can follow these steps.
+
+- Download and unzip the binary package, which is available on the [Pulsar Download](/download) page.
+
+  ```bash
+  
+  	wget https://dist.apache.org/repos/dist/release/pulsar/pulsar-manager/pulsar-manager-0.2.0/apache-pulsar-manager-0.2.0-bin.tar.gz
+  	tar -zxvf apache-pulsar-manager-0.2.0-bin.tar.gz
+  
+  ```
+
+- Extract the back-end service binary package and place the front-end resources in the back-end service directory.
+
+  ```bash
+  
+  	cd pulsar-manager
+  	tar -zxvf pulsar-manager.tar
+  	cd pulsar-manager
+  	cp -r ../dist ui
+  
+  ```
+
+- Modify `application.properties` configuration on demand.
+
+  > If you don't want to modify the `application.properties` file, you can add the configuration to the startup parameters via `. /bin/pulsar-manager --backend.jwt.token=token` to add the configuration to the startup parameters. This is a capability of the spring boot framework.
+
+- Start Pulsar Manager
+
+  ```bash
+  
+  ./bin/pulsar-manager
+  
+  ```
+
+### Custom docker image installation
+
+You can find the docker image in the [Docker Hub](https://github.com/apache/pulsar-manager/tree/master/docker) directory and build an image from the source code as well:
+
+  ```bash
+  
+  git clone https://github.com/apache/pulsar-manager
+  cd pulsar-manager/front-end
+  npm install --save
+  npm run build:prod
+  cd ..
+  ./gradlew build -x test
+  cd ..
+  docker build -f docker/Dockerfile --build-arg BUILD_DATE=`date -u +"%Y-%m-%dT%H:%M:%SZ"` --build-arg VCS_REF=`latest` --build-arg VERSION=`latest` -t apachepulsar/pulsar-manager .

+## Upgrade guidelines
+
+Apache Pulsar is comprised of multiple components, ZooKeeper, bookies, and brokers. These components are either stateful or stateless. You do not have to upgrade ZooKeeper nodes unless you have special requirement. While you upgrade, you need to pay attention to bookies (stateful), brokers and proxies (stateless).
+
+The following are some guidelines on upgrading a Pulsar cluster. Read the guidelines before upgrading.
+
+- Backup all your configuration files before upgrading.
+- Read guide entirely, make a plan, and then execute the plan. When you make upgrade plan, you need to take your specific requirements and environment into consideration.   
+- Pay attention to the upgrading order of components. In general, you do not need to upgrade your ZooKeeper or configuration store cluster (the global ZooKeeper cluster). You need to upgrade bookies first, and then upgrade brokers, proxies, and your clients. 
+- If `autorecovery` is enabled, you need to disable `autorecovery` in the upgrade process, and re-enable it after completing the process.
+- Read the release notes carefully for each release. Release notes contain features, configuration changes that might impact your upgrade.
+- Upgrade a small subset of nodes of each type to canary test the new version before upgrading all nodes of that type in the cluster. When you have upgraded the canary nodes, run for a while to ensure that they work correctly.
+- Upgrade one data center to verify new version before upgrading all data centers if your cluster runs in multi-cluster replicated mode.
+
+> Note: Currently, Apache Pulsar is compatible between versions. 
+
+## Upgrade sequence
+
+To upgrade an Apache Pulsar cluster, follow the upgrade sequence.
+
+1. Upgrade ZooKeeper (optional)  
+- Canary test: test an upgraded version in one or a small set of ZooKeeper nodes.  
+- Rolling upgrade: rollout the upgraded version to all ZooKeeper servers incrementally, one at a time. Monitor your dashboard during the whole rolling upgrade process.
+2. Upgrade bookies  
+- Canary test: test an upgraded version in one or a small set of bookies.
+- Rolling upgrade:  
+  - a. Disable `autorecovery` with the following command.
+
+     ```shell
+     
+     bin/bookkeeper shell autorecovery -disable
+     
+     ```
+
+  
+  - b. Rollout the upgraded version to all bookies in the cluster after you determine that a version is safe after canary.  
+  - c. After you upgrade all bookies, re-enable `autorecovery` with the following command.
+
+     ```shell
+     
+     bin/bookkeeper shell autorecovery -enable
+     
+     ```
+
+3. Upgrade brokers
+- Canary test: test an upgraded version in one or a small set of brokers.
+- Rolling upgrade: rollout the upgraded version to all brokers in the cluster after you determine that a version is safe after canary.
+4. Upgrade proxies
+- Canary test: test an upgraded version in one or a small set of proxies.
+- Rolling upgrade: rollout the upgraded version to all proxies in the cluster after you determine that a version is safe after canary.
+
+## Upgrade ZooKeeper (optional)
+While you upgrade ZooKeeper servers, you can do canary test first, and then upgrade all ZooKeeper servers in the cluster.
+
+### Canary test
+
+You can test an upgraded version in one of ZooKeeper servers before upgrading all ZooKeeper servers in your cluster.
+
+To upgrade ZooKeeper server to a new version, complete the following steps:
+
+1. Stop a ZooKeeper server.
+2. Upgrade the binary and configuration files.
+3. Start the ZooKeeper server with the new binary files.
+4. Use `pulsar zookeeper-shell` to connect to the newly upgraded ZooKeeper server and run a few commands to verify if it works as expected.
+5. Run the ZooKeeper server for a few days, observe and make sure the ZooKeeper cluster runs well.
+
+#### Canary rollback
+
+If issues occur during canary test, you can shut down the problematic ZooKeeper node, revert the binary and configuration, and restart the ZooKeeper with the reverted binary.
+
+### Upgrade all ZooKeeper servers
+
+After canary test to upgrade one ZooKeeper in your cluster, you can upgrade all ZooKeeper servers in your cluster. 
+
+You can upgrade all ZooKeeper servers one by one by following steps in canary test.
+
+## Upgrade bookies
+
+While you upgrade bookies, you can do canary test first, and then upgrade all bookies in the cluster.
+For more details, you can read Apache BookKeeper [Upgrade guide](http://bookkeeper.apache.org/docs/latest/admin/upgrade).
+
+### Canary test
+
+You can test an upgraded version in one or a small set of bookies before upgrading all bookies in your cluster.
+
+To upgrade bookie to a new version, complete the following steps:
+
+1. Stop a bookie.
+2. Upgrade the binary and configuration files.
+3. Start the bookie in `ReadOnly` mode to verify if the bookie of this new version runs well for read workload.
+
+   ```shell
+   
+   bin/pulsar bookie --readOnly
+   
+   ```
+
+4. When the bookie runs successfully in `ReadOnly` mode, stop the bookie and restart it in `Write/Read` mode.
+
+   ```shell
+   
+   bin/pulsar bookie
+   
+   ```
+
+5. Observe and make sure the cluster serves both write and read traffic.
+
+#### Canary rollback
+
+If issues occur during the canary test, you can shut down the problematic bookie node. Other bookies in the cluster replaces this problematic bookie node with autorecovery. 
+
+### Upgrade all bookies
+
+After canary test to upgrade some bookies in your cluster, you can upgrade all bookies in your cluster. 
+
+Before upgrading, you have to decide whether to upgrade the whole cluster at once, including downtime and rolling upgrade scenarios.
+
+In a rolling upgrade scenario, upgrade one bookie at a time. In a downtime upgrade scenario, shut down the entire cluster, upgrade each bookie, and then start the cluster.
+
+While you upgrade in both scenarios, the procedure is the same for each bookie.
+
+1. Stop the bookie. 
+2. Upgrade the software (either new binary or new configuration files).
+2. Start the bookie.
+
+> **Advanced operations**   
+> When you upgrade a large BookKeeper cluster in a rolling upgrade scenario, upgrading one bookie at a time is slow. If you configure rack-aware or region-aware placement policy, you can upgrade bookies rack by rack or region by region, which speeds up the whole upgrade process.
+
+## Upgrade brokers and proxies
+
+The upgrade procedure for brokers and proxies is the same. Brokers and proxies are `stateless`, so upgrading the two services is easy.
+
+### Canary test
+
+You can test an upgraded version in one or a small set of nodes before upgrading all nodes in your cluster.
+
+To upgrade to a new version, complete the following steps:
+
+1. Stop a broker (or proxy).
+2. Upgrade the binary and configuration file.
+3. Start a broker (or proxy).
+
+#### Canary rollback
+
+If issues occur during canary test, you can shut down the problematic broker (or proxy) node. Revert to the old version and restart the broker (or proxy).
+
+### Upgrade all brokers or proxies
+
+After canary test to upgrade some brokers or proxies in your cluster, you can upgrade all brokers or proxies in your cluster. 
+
+Before upgrading, you have to decide whether to upgrade the whole cluster at once, including downtime and rolling upgrade scenarios.
+
+In a rolling upgrade scenario, you can upgrade one broker or one proxy at a time if the size of the cluster is small. If your cluster is large, you can upgrade brokers or proxies in batches. When you upgrade a batch of brokers or proxies, make sure the remaining brokers and proxies in the cluster have enough capacity to handle the traffic during upgrade.
+
+In a downtime upgrade scenario, shut down the entire cluster, upgrade each broker or proxy, and then start the cluster.
+
+While you upgrade in both scenarios, the procedure is the same for each broker or proxy.
+
+1. Stop the broker or proxy. 
+2. Upgrade the software (either new binary or new configuration files).
+3. Start the broker or proxy.

+
+Pulsar relies on two external systems for essential tasks:
+
+* [ZooKeeper](https://zookeeper.apache.org/) is responsible for a wide variety of configuration-related and coordination-related tasks.
+* [BookKeeper](http://bookkeeper.apache.org/) is responsible for [persistent storage](concepts-architecture-overview.md#persistent-storage) of message data.
+
+ZooKeeper and BookKeeper are both open-source [Apache](https://www.apache.org/) projects.
+
+> Skip to the [How Pulsar uses ZooKeeper and BookKeeper](#how-pulsar-uses-zookeeper-and-bookkeeper) section below for a more schematic explanation of the role of these two systems in Pulsar.
+
+
+## ZooKeeper
+
+Each Pulsar instance relies on two separate ZooKeeper quorums.
+
+* [Local ZooKeeper](#deploy-local-zookeeper) operates at the cluster level and provides cluster-specific configuration management and coordination. Each Pulsar cluster needs to have a dedicated ZooKeeper cluster.
+* [Configuration Store](#deploy-configuration-store) operates at the instance level and provides configuration management for the entire system (and thus across clusters). An independent cluster of machines or the same machines that local ZooKeeper uses can provide the configuration store quorum. 
+
+### Deploy local ZooKeeper
+
+ZooKeeper manages a variety of essential coordination-related and configuration-related tasks for Pulsar.
+
+To deploy a Pulsar instance, you need to stand up one local ZooKeeper cluster *per Pulsar cluster*.
+
+To begin, add all ZooKeeper servers to the quorum configuration specified in the [`conf/zookeeper.conf`](reference-configuration.md#zookeeper) file. Add a `server.N` line for each node in the cluster to the configuration, where `N` is the number of the ZooKeeper node. The following is an example for a three-node cluster:
+
+```properties
+
+server.1=zk1.us-west.example.com:2888:3888
+server.2=zk2.us-west.example.com:2888:3888
+server.3=zk3.us-west.example.com:2888:3888
+
+```
+
+On each host, you need to specify the node ID in `myid` file of each node, which is in `data/zookeeper` folder of each server by default (you can change the file location via the [`dataDir`](reference-configuration.md#zookeeper-dataDir) parameter).
+
+> See the [Multi-server setup guide](https://zookeeper.apache.org/doc/r3.4.10/zookeeperAdmin.html#sc_zkMulitServerSetup) in the ZooKeeper documentation for detailed information on `myid` and more.
+
+
+On a ZooKeeper server at `zk1.us-west.example.com`, for example, you can set the `myid` value like this:
+
+```shell
+
+$ mkdir -p data/zookeeper
+$ echo 1 > data/zookeeper/myid
+
+```
+
+On `zk2.us-west.example.com` the command is `echo 2 > data/zookeeper/myid` and so on.
+
+Once you add each server to the `zookeeper.conf` configuration and each server has the appropriate `myid` entry, you can start ZooKeeper on all hosts (in the background, using nohup) with the [`pulsar-daemon`](reference-cli-tools.md#pulsar-daemon) CLI tool:
+
+```shell
+
+$ bin/pulsar-daemon start zookeeper
+
+```
+
+### Deploy configuration store
+
+The ZooKeeper cluster configured and started up in the section above is a *local* ZooKeeper cluster that you can use to manage a single Pulsar cluster. In addition to a local cluster, however, a full Pulsar instance also requires a configuration store for handling some instance-level configuration and coordination tasks.
+
+If you deploy a [single-cluster](#single-cluster-pulsar-instance) instance, you do not need a separate cluster for the configuration store. If, however, you deploy a [multi-cluster](#multi-cluster-pulsar-instance) instance, you need to stand up a separate ZooKeeper cluster for configuration tasks.
+
+#### Single-cluster Pulsar instance
+
+If your Pulsar instance consists of just one cluster, then you can deploy a configuration store on the same machines as the local ZooKeeper quorum but run on different TCP ports.
+
+To deploy a ZooKeeper configuration store in a single-cluster instance, add the same ZooKeeper servers that the local quorum uses to the configuration file in [`conf/global_zookeeper.conf`](reference-configuration.md#configuration-store) using the same method for [local ZooKeeper](#local-zookeeper), but make sure to use a different port (2181 is the default for ZooKeeper). The following is an example that uses port 2184 for a three-node ZooKeeper cluster:
+
+```properties
+
+clientPort=2184
+server.1=zk1.us-west.example.com:2185:2186
+server.2=zk2.us-west.example.com:2185:2186
+server.3=zk3.us-west.example.com:2185:2186
+
+```
+
+As before, create the `myid` files for each server on `data/global-zookeeper/myid`.
+
+#### Multi-cluster Pulsar instance
+
+When you deploy a global Pulsar instance, with clusters distributed across different geographical regions, the configuration store serves as a highly available and strongly consistent metadata store that can tolerate failures and partitions spanning whole regions.
+
+The key here is to make sure the ZK quorum members are spread across at least 3 regions and that other regions run as observers.
+
+Again, given the very low expected load on the configuration store servers, you can share the same hosts used for the local ZooKeeper quorum.
+
+For example, you can assume a Pulsar instance with the following clusters `us-west`, `us-east`, `us-central`, `eu-central`, `ap-south`. Also you can assume, each cluster has its own local ZK servers named such as
+
+```
+
+zk[1-3].${CLUSTER}.example.com
+
+```
+
+In this scenario you want to pick the quorum participants from few clusters and let all the others be ZK observers. For example, to form a 7 servers quorum, you can pick 3 servers from `us-west`, 2 from `us-central` and 2 from `us-east`.
+
+This guarantees that writes to configuration store is possible even if one of these regions is unreachable.
+
+The ZK configuration in all the servers looks like:
+
+```properties
+
+clientPort=2184
+server.1=zk1.us-west.example.com:2185:2186
+server.2=zk2.us-west.example.com:2185:2186
+server.3=zk3.us-west.example.com:2185:2186
+server.4=zk1.us-central.example.com:2185:2186
+server.5=zk2.us-central.example.com:2185:2186
+server.6=zk3.us-central.example.com:2185:2186:observer
+server.7=zk1.us-east.example.com:2185:2186
+server.8=zk2.us-east.example.com:2185:2186
+server.9=zk3.us-east.example.com:2185:2186:observer
+server.10=zk1.eu-central.example.com:2185:2186:observer
+server.11=zk2.eu-central.example.com:2185:2186:observer
+server.12=zk3.eu-central.example.com:2185:2186:observer
+server.13=zk1.ap-south.example.com:2185:2186:observer
+server.14=zk2.ap-south.example.com:2185:2186:observer
+server.15=zk3.ap-south.example.com:2185:2186:observer
+
+```
+
+Additionally, ZK observers need to have:
+
+```properties
+
+peerType=observer
+
+```
+
+##### Start the service
+
+Once your configuration store configuration is in place, you can start up the service using [`pulsar-daemon`](reference-cli-tools.md#pulsar-daemon)
+
+```shell
+
+$ bin/pulsar-daemon start configuration-store
+
+```
+
+### ZooKeeper configuration
+
+In Pulsar, ZooKeeper configuration is handled by two separate configuration files in the `conf` directory of your Pulsar installation:
+* The `conf/zookeeper.conf` file handles the configuration for local ZooKeeper.
+* The `conf/global-zookeeper.conf` file handles the configuration for configuration store.
+See [parameters](reference-configuration.md#zookeeper) for more details.
+
+#### Configure batching operations
+Using the batching operations reduces the remote procedure call (RPC) traffic between ZooKeeper client and servers. It also reduces the number of write transactions, because each batching operation corresponds to a single ZooKeeper transaction, containing multiple read and write operations.
+
+The following figure demonstrates a basic benchmark of batching read/write operations that can be requested to ZooKeeper in one second:
+
+![Zookeeper batching benchmark](/assets/zookeeper-batching.png)
+
+To enable batching operations, set the [`metadataStoreBatchingEnabled`](reference-configuration.md#broker) parameter to `true` on the broker side.
+
+
+## BookKeeper
+
+BookKeeper stores all durable messages in Pulsar. BookKeeper is a distributed [write-ahead log](https://en.wikipedia.org/wiki/Write-ahead_logging) WAL system that guarantees read consistency of independent message logs calls ledgers. Individual BookKeeper servers are also called *bookies*.
+
+> To manage message persistence, retention, and expiry in Pulsar, refer to [cookbook](cookbooks-retention-expiry.md).
+
+### Hardware requirements
+
+Bookie hosts store message data on disk. To provide optimal performance, ensure that the bookies have a suitable hardware configuration. The following are two key dimensions of bookie hardware capacity:
+
+- Disk I/O capacity read/write
+- Storage capacity
+
+Message entries written to bookies are always synced to disk before returning an acknowledgement to the Pulsar broker by default. To ensure low write latency, BookKeeper is designed to use multiple devices:
+
+- A **journal** to ensure durability. For sequential writes, it is critical to have fast [fsync](https://linux.die.net/man/2/fsync) operations on bookie hosts. Typically, small and fast [solid-state drives](https://en.wikipedia.org/wiki/Solid-state_drive) (SSDs) should suffice, or [hard disk drives](https://en.wikipedia.org/wiki/Hard_disk_drive) (HDDs) with a [RAID](https://en.wikipedia.org/wiki/RAID) controller and a battery-backed write cache. Both solutions can reach fsync latency of  [...]
+- A **ledger storage device** stores data. Writes happen in the background, so write I/O is not a big concern. Reads happen sequentially most of the time and the backlog is drained only in case of consumer drain. To store large amounts of data, a typical configuration involves multiple HDDs with a RAID controller.
+
+### Configure BookKeeper
+
+You can configure BookKeeper bookies using the [`conf/bookkeeper.conf`](reference-configuration.md#bookkeeper) configuration file. When you configure each bookie, ensure that the [`zkServers`](reference-configuration.md#bookkeeper-zkServers) parameter is set to the connection string for local ZooKeeper of the Pulsar cluster.
+
+The minimum configuration changes required in `conf/bookkeeper.conf` are as follows:
+
+:::note
+
+Set `journalDirectory` and `ledgerDirectories` carefully. It is difficilt to change them later.
+
+:::
+
+```properties
+
+# Change to point to journal disk mount point
+journalDirectory=data/bookkeeper/journal
+
+# Point to ledger storage disk mount point
+ledgerDirectories=data/bookkeeper/ledgers
+
+# Point to local ZK quorum
+zkServers=zk1.example.com:2181,zk2.example.com:2181,zk3.example.com:2181
+
+#It is recommended to set this parameter. Otherwise, BookKeeper can't start normally in certain environments (for example, Huawei Cloud).
+advertisedAddress=
+
+```
+
+To change the ZooKeeper root path that BookKeeper uses, use `zkLedgersRootPath=/MY-PREFIX/ledgers` instead of `zkServers=localhost:2181/MY-PREFIX`.
+
+> For more information about BookKeeper, refer to the official [BookKeeper docs](http://bookkeeper.apache.org).
+
+### Deploy BookKeeper
+
+BookKeeper provides [persistent message storage](concepts-architecture-overview.md#persistent-storage) for Pulsar. Each Pulsar broker has its own cluster of bookies. The BookKeeper cluster shares a local ZooKeeper quorum with the Pulsar cluster.
+
+### Start bookies manually
+
+You can start a bookie in the foreground or as a background daemon.
+
+To start a bookie in the foreground, use the [`bookkeeper`](reference-cli-tools.md#bookkeeper) CLI tool:
+
+```bash
+
+$ bin/bookkeeper bookie
+
+```
+
+To start a bookie in the background, use the [`pulsar-daemon`](reference-cli-tools.md#pulsar-daemon) CLI tool:
+
+```bash
+
+$ bin/pulsar-daemon start bookie
+
+```
+
+You can verify whether the bookie works properly with the `bookiesanity` command for the [BookKeeper shell](reference-cli-tools.md#bookkeeper-shell):
+
+```shell
+
+$ bin/bookkeeper shell bookiesanity
+
+```
+
+When you use this command, you create a new ledger on the local bookie, write a few entries, read them back and finally delete the ledger.
+
+### Decommission bookies cleanly
+
+Before you decommission a bookie, you need to check your environment and meet the following requirements.
+
+1. Ensure the state of your cluster supports decommissioning the target bookie. Check if `EnsembleSize >= Write Quorum >= Ack Quorum` is `true` with one less bookie.
+
+2. Ensure the target bookie is listed after using the `listbookies` command.
+
+3. Ensure that no other process is ongoing (upgrade etc).
+
+And then you can decommission bookies safely. To decommission bookies, complete the following steps.
+
+1. Log in to the bookie node, check if there are underreplicated ledgers. The decommission command force to replicate the underreplicated ledgers.
+`$ bin/bookkeeper shell listunderreplicated`
+
+2. Stop the bookie by killing the bookie process. Make sure that no liveness/readiness probes setup for the bookies to spin them back up if you deploy it in a Kubernetes environment.
+
+3. Run the decommission command.
+   - If you have logged in to the node to be decommissioned, you do not need to provide `-bookieid`.
+   - If you are running the decommission command for the target bookie node from another bookie node, you should mention the target bookie ID in the arguments for `-bookieid`
+   `$ bin/bookkeeper shell decommissionbookie`
+   or
+   `$ bin/bookkeeper shell decommissionbookie -bookieid <target bookieid>`
+
+4. Validate that no ledgers are on the decommissioned bookie.   
+`$ bin/bookkeeper shell listledgers -bookieid <target bookieid>`
+
+You can run the following command to check if the bookie you have decommissioned is listed in the bookies list:
+
+```bash
+
+./bookkeeper shell listbookies -rw -h
+./bookkeeper shell listbookies -ro -h
+
+```
+
+## BookKeeper persistence policies
+
+In Pulsar, you can set *persistence policies* at the namespace level, which determines how BookKeeper handles persistent storage of messages. Policies determine four things:
+
+* The number of acks (guaranteed copies) to wait for each ledger entry.
+* The number of bookies to use for a topic.
+* The number of writes to make for each ledger entry.
+* The throttling rate for mark-delete operations.
+
+### Set persistence policies
+
+You can set persistence policies for BookKeeper at the [namespace](reference-terminology.md#namespace) level.
+
+#### Pulsar-admin
+
+Use the [`set-persistence`](reference-pulsar-admin.md#namespaces-set-persistence) subcommand and specify a namespace as well as any policies that you want to apply. The available flags are:
+
+Flag | Description | Default
+:----|:------------|:-------
+`-a`, `--bookkeeper-ack-quorum` | The number of acks (guaranteed copies) to wait on for each entry | 0
+`-e`, `--bookkeeper-ensemble` | The number of [bookies](reference-terminology.md#bookie) to use for topics in the namespace | 0
+`-w`, `--bookkeeper-write-quorum` | The number of writes to make for each entry | 0
+`-r`, `--ml-mark-delete-max-rate` | Throttling rate for mark-delete operations (0 means no throttle) | 0
+
+The following is an example:
+
+```shell
+
+$ pulsar-admin namespaces set-persistence my-tenant/my-ns \
+  --bookkeeper-ack-quorum 3 \
+  --bookkeeper-ensemble 2
+
+```
+
+#### REST API
+
+{@inject: endpoint|POST|/admin/v2/namespaces/:tenant/:namespace/persistence|operation/setPersistence?version=@pulsar:version_number@}
+
+#### Java
+
+```java
+
+int bkEnsemble = 2;
+int bkQuorum = 3;
+int bkAckQuorum = 2;
+double markDeleteRate = 0.7;
+PersistencePolicies policies =
+  new PersistencePolicies(ensemble, quorum, ackQuorum, markDeleteRate);
+admin.namespaces().setPersistence(namespace, policies);
+
+```
+
+### List persistence policies
+
+You can see which persistence policy currently applies to a namespace.
+
+#### Pulsar-admin
+
+Use the [`get-persistence`](reference-pulsar-admin.md#namespaces-get-persistence) subcommand and specify the namespace.
+
+The following is an example:
+
+```shell
+
+$ pulsar-admin namespaces get-persistence my-tenant/my-ns
+{

+sidebar_label: "CGo(deprecated)"
+original_id: client-libraries-cgo
+---
+
+> The CGo client has been deprecated since version 2.7.0. If possible, use the [Go client](client-libraries-go.md) instead.
+
+You can use Pulsar Go client to create Pulsar [producers](#producers), [consumers](#consumers), and [readers](#readers) in Go (aka Golang).
+
+All the methods in [producers](#producers), [consumers](#consumers), and [readers](#readers) of a Go client are thread-safe.
+
+Currently, the following Go clients are maintained in two repositories.

+> For standard API docs, consult the [Godoc](https://godoc.org/github.com/apache/pulsar/pulsar-client-go/pulsar).
+
+## Installation
+
+### Requirements
+
+Pulsar Go client library is based on the C++ client library. Follow
+the instructions for [C++ library](client-libraries-cpp.md) for installing the binaries through [RPM](client-libraries-cpp.md#rpm), [Deb](client-libraries-cpp.md#deb) or [Homebrew packages](client-libraries-cpp.md#macos).
+
+### Install go package
+
+> **Compatibility Warning**  
+> The version number of the Go client **must match** the version number of the Pulsar C++ client library.
+
+You can install the `pulsar` library locally using `go get`.  Note that `go get` doesn't support fetching a specific tag - it will always pull in master's version of the Go client.  You'll need a C++ client library that matches master.
+
+```bash
+
+$ go get -u github.com/apache/pulsar/pulsar-client-go/pulsar
+
+```
+
+Or you can use [dep](https://github.com/golang/dep) for managing the dependencies.
+
+```bash
+
+$ dep ensure -add github.com/apache/pulsar/pulsar-client-go/pulsar@v@pulsar:version@
+
+```
+
+Once installed locally, you can import it into your project:
+
+```go
+
+import "github.com/apache/pulsar/pulsar-client-go/pulsar"
+
+```
+
+## Connection URLs
+
+To connect to Pulsar using client libraries, you need to specify a [Pulsar protocol](developing-binary-protocol.md) URL.
+
+Pulsar protocol URLs are assigned to specific clusters, use the `pulsar` scheme and have a default port of 6650. Here's an example for `localhost`:
+
+```http
+
+pulsar://localhost:6650
+
+```
+
+A URL for a production Pulsar cluster may look something like this:
+
+```http
+
+pulsar://pulsar.us-west.example.com:6650
+
+```
+
+If you're using [TLS](security-tls-authentication.md) authentication, the URL will look like something like this:
+
+```http
+
+pulsar+ssl://pulsar.us-west.example.com:6651
+
+```
+
+## Create a client
+
+In order to interact with Pulsar, you'll first need a `Client` object. You can create a client object using the `NewClient` function, passing in a `ClientOptions` object (more on configuration [below](#client-configuration)). Here's an example:
+
+```go
+
+import (
+    "log"
+    "runtime"
+
+    "github.com/apache/pulsar/pulsar-client-go/pulsar"
+)
+
+func main() {
+    client, err := pulsar.NewClient(pulsar.ClientOptions{
+        URL: "pulsar://localhost:6650",
+        OperationTimeoutSeconds: 5,
+        MessageListenerThreads: runtime.NumCPU(),
+    })
+
+    if err != nil {
+        log.Fatalf("Could not instantiate Pulsar client: %v", err)
+    }
+}
+
+```
+
+The following configurable parameters are available for Pulsar clients:
+
+Parameter | Description | Default
+:---------|:------------|:-------
+`URL` | The connection URL for the Pulsar cluster. See [above](#urls) for more info |
+`IOThreads` | The number of threads to use for handling connections to Pulsar [brokers](reference-terminology.md#broker) | 1
+`OperationTimeoutSeconds` | The timeout for some Go client operations (creating producers, subscribing to and unsubscribing from [topics](reference-terminology.md#topic)). Retries will occur until this threshold is reached, at which point the operation will fail. | 30
+`MessageListenerThreads` | The number of threads used by message listeners ([consumers](#consumers) and [readers](#readers)) | 1
+`ConcurrentLookupRequests` | The number of concurrent lookup requests that can be sent on each broker connection. Setting a maximum helps to keep from overloading brokers. You should set values over the default of 5000 only if the client needs to produce and/or subscribe to thousands of Pulsar topics. | 5000
+`Logger` | A custom logger implementation for the client (as a function that takes a log level, file path, line number, and message). All info, warn, and error messages will be routed to this function. | `nil`
+`TLSTrustCertsFilePath` | The file path for the trusted TLS certificate |
+`TLSAllowInsecureConnection` | Whether the client accepts untrusted TLS certificates from the broker | `false`
+`Authentication` | Configure the authentication provider. (default: no authentication). Example: `Authentication: NewAuthenticationTLS("my-cert.pem", "my-key.pem")` | `nil`
+`StatsIntervalInSeconds` | The interval (in seconds) at which client stats are published | 60
+
+## Producers
+
+Pulsar producers publish messages to Pulsar topics. You can [configure](#producer-configuration) Go producers using a `ProducerOptions` object. Here's an example:
+
+```go
+
+producer, err := client.CreateProducer(pulsar.ProducerOptions{
+    Topic: "my-topic",
+})
+
+if err != nil {
+    log.Fatalf("Could not instantiate Pulsar producer: %v", err)
+}
+
+defer producer.Close()
+
+msg := pulsar.ProducerMessage{
+    Payload: []byte("Hello, Pulsar"),
+}
+
+if err := producer.Send(context.Background(), msg); err != nil {
+    log.Fatalf("Producer could not send message: %v", err)
+}
+
+```
+
+> **Blocking operation**  
+> When you create a new Pulsar producer, the operation will block (waiting on a go channel) until either a producer is successfully created or an error is thrown.
+
+
+### Producer operations
+
+Pulsar Go producers have the following methods available:
+
+Method | Description | Return type
+:------|:------------|:-----------
+`Topic()` | Fetches the producer's [topic](reference-terminology.md#topic)| `string`
+`Name()` | Fetches the producer's name | `string`
+`Send(context.Context, ProducerMessage)` | Publishes a [message](#messages) to the producer's topic. This call will block until the message is successfully acknowledged by the Pulsar broker, or an error will be thrown if the timeout set using the `SendTimeout` in the producer's [configuration](#producer-configuration) is exceeded. | `error`
+`SendAndGetMsgID(context.Context, ProducerMessage)`| Send a message, this call will be blocking until is successfully acknowledged by the Pulsar broker. | (MessageID, error)
+`SendAsync(context.Context, ProducerMessage, func(ProducerMessage, error))` | Publishes a [message](#messages) to the producer's topic asynchronously. The third argument is a callback function that specifies what happens either when the message is acknowledged or an error is thrown. |
+`SendAndGetMsgIDAsync(context.Context, ProducerMessage, func(MessageID, error))`| Send a message in asynchronous mode. The callback will report back the message being published and the eventual error in publishing | 
+`LastSequenceID()` | Get the last sequence id that was published by this producer. his represent either the automatically assigned or custom sequence id (set on the ProducerMessage) that was published and acknowledged by the broker. | int64
+`Flush()`| Flush all the messages buffered in the client and wait until all messages have been successfully persisted. | error
+`Close()` | Closes the producer and releases all resources allocated to it. If `Close()` is called then no more messages will be accepted from the publisher. This method will block until all pending publish requests have been persisted by Pulsar. If an error is thrown, no pending writes will be retried. | `error`
+`Schema()` | | Schema
+
+Here's a more involved example usage of a producer:
+
+```go
+
+import (
+    "context"
+    "fmt"
+    "log"
+
+    "github.com/apache/pulsar/pulsar-client-go/pulsar"
+)
+
+func main() {
+    // Instantiate a Pulsar client
+    client, err := pulsar.NewClient(pulsar.ClientOptions{
+        URL: "pulsar://localhost:6650",
+    })
+
+    if err != nil { log.Fatal(err) }
+
+    // Use the client to instantiate a producer
+    producer, err := client.CreateProducer(pulsar.ProducerOptions{
+        Topic: "my-topic",
+    })
+
+    if err != nil { log.Fatal(err) }
+
+    ctx := context.Background()
+
+    // Send 10 messages synchronously and 10 messages asynchronously
+    for i := 0; i < 10; i++ {
+        // Create a message
+        msg := pulsar.ProducerMessage{
+            Payload: []byte(fmt.Sprintf("message-%d", i)),
+        }
+
+        // Attempt to send the message
+        if err := producer.Send(ctx, msg); err != nil {
+            log.Fatal(err)
+        }
+
+        // Create a different message to send asynchronously
+        asyncMsg := pulsar.ProducerMessage{
+            Payload: []byte(fmt.Sprintf("async-message-%d", i)),
+        }
+
+        // Attempt to send the message asynchronously and handle the response
+        producer.SendAsync(ctx, asyncMsg, func(msg pulsar.ProducerMessage, err error) {
+            if err != nil { log.Fatal(err) }
+
+            fmt.Printf("the %s successfully published", string(msg.Payload))
+        })
+    }
+}
+
+```
+
+### Producer configuration
+
+Parameter | Description | Default
+:---------|:------------|:-------
+`Topic` | The Pulsar [topic](reference-terminology.md#topic) to which the producer will publish messages |
+`Name` | A name for the producer. If you don't explicitly assign a name, Pulsar will automatically generate a globally unique name that you can access later using the `Name()` method.  If you choose to explicitly assign a name, it will need to be unique across *all* Pulsar clusters, otherwise the creation operation will throw an error. |
+`Properties`| Attach a set of application defined properties to the producer. This properties will be visible in the topic stats | 
+`SendTimeout` | When publishing a message to a topic, the producer will wait for an acknowledgment from the responsible Pulsar [broker](reference-terminology.md#broker). If a message is not acknowledged within the threshold set by this parameter, an error will be thrown. If you set `SendTimeout` to -1, the timeout will be set to infinity (and thus removed). Removing the send timeout is recommended when using Pulsar's [message de-duplication](cookbooks-deduplication.md) feature. | 30 seconds
+`MaxPendingMessages` | The maximum size of the queue holding pending messages (i.e. messages waiting to receive an acknowledgment from the [broker](reference-terminology.md#broker)). By default, when the queue is full all calls to the `Send` and `SendAsync` methods will fail *unless* `BlockIfQueueFull` is set to `true`. |
+`MaxPendingMessagesAcrossPartitions` | Set the number of max pending messages across all the partitions. This setting will be used to lower the max pending messages for each partition `MaxPendingMessages(int)`, if the total exceeds the configured value.|
+`BlockIfQueueFull` | If set to `true`, the producer's `Send` and `SendAsync` methods will block when the outgoing message queue is full rather than failing and throwing an error (the size of that queue is dictated by the `MaxPendingMessages` parameter); if set to `false` (the default), `Send` and `SendAsync` operations will fail and throw a `ProducerQueueIsFullError` when the queue is full. | `false`
+`MessageRoutingMode` | The message routing logic (for producers on [partitioned topics](concepts-architecture-overview.md#partitioned-topics)). This logic is applied only when no key is set on messages. The available options are: round robin (`pulsar.RoundRobinDistribution`, the default), publishing all messages to a single partition (`pulsar.UseSinglePartition`), or a custom partitioning scheme (`pulsar.CustomPartition`). | `pulsar.RoundRobinDistribution`
+`HashingScheme` | The hashing function that determines the partition on which a particular message is published (partitioned topics only). The available options are: `pulsar.JavaStringHash` (the equivalent of `String.hashCode()` in Java), `pulsar.Murmur3_32Hash` (applies the [Murmur3](https://en.wikipedia.org/wiki/MurmurHash) hashing function), or `pulsar.BoostHash` (applies the hashing function from C++'s [Boost](https://www.boost.org/doc/libs/1_62_0/doc/html/hash.html) library) | `puls [...]
+`CompressionType` | The message data compression type used by the producer. The available options are [`LZ4`](https://github.com/lz4/lz4), [`ZLIB`](https://zlib.net/), [`ZSTD`](https://facebook.github.io/zstd/) and [`SNAPPY`](https://google.github.io/snappy/). | No compression
+`MessageRouter` | By default, Pulsar uses a round-robin routing scheme for [partitioned topics](cookbooks-partitioned.md). The `MessageRouter` parameter enables you to specify custom routing logic via a function that takes the Pulsar message and topic metadata as an argument and returns an integer (where the ), i.e. a function signature of `func(Message, TopicMetadata) int`. |
+`Batching` | Control whether automatic batching of messages is enabled for the producer. | false
+`BatchingMaxPublishDelay` | Set the time period within which the messages sent will be batched (default: 1ms) if batch messages are enabled. If set to a non zero value, messages will be queued until this time interval or until | 1ms
+`BatchingMaxMessages` | Set the maximum number of messages permitted in a batch. (default: 1000) If set to a value greater than 1, messages will be queued until this threshold is reached or batch interval has elapsed | 1000
+
+## Consumers
+
+Pulsar consumers subscribe to one or more Pulsar topics and listen for incoming messages produced on that topic/those topics. You can [configure](#consumer-configuration) Go consumers using a `ConsumerOptions` object. Here's a basic example that uses channels:
+
+```go
+
+msgChannel := make(chan pulsar.ConsumerMessage)
+
+consumerOpts := pulsar.ConsumerOptions{
+    Topic:            "my-topic",
+    SubscriptionName: "my-subscription-1",
+    Type:             pulsar.Exclusive,
+    MessageChannel:   msgChannel,
+}
+
+consumer, err := client.Subscribe(consumerOpts)
+
+if err != nil {
+    log.Fatalf("Could not establish subscription: %v", err)
+}
+
+defer consumer.Close()
+
+for cm := range msgChannel {
+    msg := cm.Message
+
+    fmt.Printf("Message ID: %s", msg.ID())
+    fmt.Printf("Message value: %s", string(msg.Payload()))
+
+    consumer.Ack(msg)
+}
+
+```
+
+> **Blocking operation**  
+> When you create a new Pulsar consumer, the operation will block (on a go channel) until either a producer is successfully created or an error is thrown.
+
+
+### Consumer operations
+
+Pulsar Go consumers have the following methods available:
+
+Method | Description | Return type
+:------|:------------|:-----------
+`Topic()` | Returns the consumer's [topic](reference-terminology.md#topic) | `string`
+`Subscription()` | Returns the consumer's subscription name | `string`
+`Unsubcribe()` | Unsubscribes the consumer from the assigned topic. Throws an error if the unsubscribe operation is somehow unsuccessful. | `error`
+`Receive(context.Context)` | Receives a single message from the topic. This method blocks until a message is available. | `(Message, error)`
+`Ack(Message)` | [Acknowledges](reference-terminology.md#acknowledgment-ack) a message to the Pulsar [broker](reference-terminology.md#broker) | `error`
+`AckID(MessageID)` | [Acknowledges](reference-terminology.md#acknowledgment-ack) a message to the Pulsar [broker](reference-terminology.md#broker) by message ID | `error`
+`AckCumulative(Message)` | [Acknowledges](reference-terminology.md#acknowledgment-ack) *all* the messages in the stream, up to and including the specified message. The `AckCumulative` method will block until the ack has been sent to the broker. After that, the messages will *not* be redelivered to the consumer. Cumulative acking can only be used with a [shared](concepts-messaging.md#shared) subscription type. | `error`
+`AckCumulativeID(MessageID)` |Ack the reception of all the messages in the stream up to (and including) the provided message. This method will block until the acknowledge has been sent to the broker. After that, the messages will not be re-delivered to this consumer. | error
+`Nack(Message)` | Acknowledge the failure to process a single message. | `error`
+`NackID(MessageID)` | Acknowledge the failure to process a single message. | `error`
+`Close()` | Closes the consumer, disabling its ability to receive messages from the broker | `error`
+`RedeliverUnackedMessages()` | Redelivers *all* unacknowledged messages on the topic. In [failover](concepts-messaging.md#failover) mode, this request is ignored if the consumer isn't active on the specified topic; in [shared](concepts-messaging.md#shared) mode, redelivered messages are distributed across all consumers connected to the topic. **Note**: this is a *non-blocking* operation that doesn't throw an error. |
+`Seek(msgID MessageID)` | Reset the subscription associated with this consumer to a specific message id. The message id can either be a specific message or represent the first or last messages in the topic. | error
+
+#### Receive example
+
+Here's an example usage of a Go consumer that uses the `Receive()` method to process incoming messages:
+
+```go
+
+import (
+    "context"
+    "log"
+
+    "github.com/apache/pulsar/pulsar-client-go/pulsar"
+)
+
+func main() {
+    // Instantiate a Pulsar client
+    client, err := pulsar.NewClient(pulsar.ClientOptions{
+            URL: "pulsar://localhost:6650",
+    })
+
+    if err != nil { log.Fatal(err) }
+
+    // Use the client object to instantiate a consumer
+    consumer, err := client.Subscribe(pulsar.ConsumerOptions{
+        Topic:            "my-golang-topic",
+        SubscriptionName: "sub-1",
+        Type: pulsar.Exclusive,
+    })
+
+    if err != nil { log.Fatal(err) }
+
+    defer consumer.Close()
+
+    ctx := context.Background()
+
+    // Listen indefinitely on the topic
+    for {
+        msg, err := consumer.Receive(ctx)
+        if err != nil { log.Fatal(err) }
+
+        // Do something with the message
+        err = processMessage(msg)
+
+        if err == nil {
+            // Message processed successfully
+            consumer.Ack(msg)
+        } else {
+            // Failed to process messages
+            consumer.Nack(msg)
+        }
+    }
+}
+
+```
+
+### Consumer configuration
+
+Parameter | Description | Default
+:---------|:------------|:-------
+`Topic` | The Pulsar [topic](reference-terminology.md#topic) on which the consumer will establish a subscription and listen for messages |
+`Topics` | Specify a list of topics this consumer will subscribe on. Either a topic, a list of topics or a topics pattern are required when subscribing |
+`TopicsPattern` | Specify a regular expression to subscribe to multiple topics under the same namespace. Either a topic, a list of topics or a topics pattern are required when subscribing |
+`SubscriptionName` | The subscription name for this consumer |
+`Properties` | Attach a set of application defined properties to the consumer. This properties will be visible in the topic stats|
+`Name` | The name of the consumer |
+`AckTimeout` | Set the timeout for unacked messages | 0
+`NackRedeliveryDelay` | The delay after which to redeliver the messages that failed to be processed. Default is 1min. (See `Consumer.Nack()`) | 1 minute
+`Type` | Available options are `Exclusive`, `Shared`, and `Failover` | `Exclusive`
+`SubscriptionInitPos` | InitialPosition at which the cursor will be set when subscribe | Latest
+`MessageChannel` | The Go channel used by the consumer. Messages that arrive from the Pulsar topic(s) will be passed to this channel. |
+`ReceiverQueueSize` | Sets the size of the consumer's receiver queue, i.e. the number of messages that can be accumulated by the consumer before the application calls `Receive`. A value higher than the default of 1000 could increase consumer throughput, though at the expense of more memory utilization. | 1000
+`MaxTotalReceiverQueueSizeAcrossPartitions` |Set the max total receiver queue size across partitions. This setting will be used to reduce the receiver queue size for individual partitions if the total exceeds this value | 50000
+`ReadCompacted` | If enabled, the consumer will read messages from the compacted topic rather than reading the full message backlog of the topic. This means that, if the topic has been compacted, the consumer will only see the latest value for each key in the topic, up until the point in the topic message backlog that has been compacted. Beyond that point, the messages will be sent as normal. |
+
+## Readers
+
+Pulsar readers process messages from Pulsar topics. Readers are different from consumers because with readers you need to explicitly specify which message in the stream you want to begin with (consumers, on the other hand, automatically begin with the most recent unacked message). You can [configure](#reader-configuration) Go readers using a `ReaderOptions` object. Here's an example:
+
+```go
+
+reader, err := client.CreateReader(pulsar.ReaderOptions{
+    Topic: "my-golang-topic",
+    StartMessageId: pulsar.LatestMessage,
+})
+
+```
+
+> **Blocking operation**  
+> When you create a new Pulsar reader, the operation will block (on a go channel) until either a reader is successfully created or an error is thrown.
+
+
+### Reader operations
+
+Pulsar Go readers have the following methods available:
+
+Method | Description | Return type
+:------|:------------|:-----------
+`Topic()` | Returns the reader's [topic](reference-terminology.md#topic) | `string`
+`Next(context.Context)` | Receives the next message on the topic (analogous to the `Receive` method for [consumers](#consumer-operations)). This method blocks until a message is available. | `(Message, error)`
+`HasNext()` | Check if there is any message available to read from the current position| (bool, error)
+`Close()` | Closes the reader, disabling its ability to receive messages from the broker | `error`
+
+#### "Next" example
+
+Here's an example usage of a Go reader that uses the `Next()` method to process incoming messages:
+
+```go
+
+import (
+    "context"
+    "log"
+
+    "github.com/apache/pulsar/pulsar-client-go/pulsar"
+)
+
+func main() {
+    // Instantiate a Pulsar client
+    client, err := pulsar.NewClient(pulsar.ClientOptions{
+            URL: "pulsar://localhost:6650",
+    })
+
+    if err != nil { log.Fatalf("Could not create client: %v", err) }
+
+    // Use the client to instantiate a reader
+    reader, err := client.CreateReader(pulsar.ReaderOptions{
+        Topic:          "my-golang-topic",
+        StartMessageID: pulsar.EarliestMessage,
+    })
+
+    if err != nil { log.Fatalf("Could not create reader: %v", err) }
+
+    defer reader.Close()
+
+    ctx := context.Background()
+
+    // Listen on the topic for incoming messages
+    for {
+        msg, err := reader.Next(ctx)
+        if err != nil { log.Fatalf("Error reading from topic: %v", err) }
+
+        // Process the message
+    }
+}
+
+```
+
+In the example above, the reader begins reading from the earliest available message (specified by `pulsar.EarliestMessage`). The reader can also begin reading from the latest message (`pulsar.LatestMessage`) or some other message ID specified by bytes using the `DeserializeMessageID` function, which takes a byte array and returns a `MessageID` object. Here's an example:
+
+```go
+
+lastSavedId := // Read last saved message id from external store as byte[]
+
+reader, err := client.CreateReader(pulsar.ReaderOptions{
+    Topic:          "my-golang-topic",
+    StartMessageID: DeserializeMessageID(lastSavedId),
+})
+
+```
+
+### Reader configuration
+
+Parameter | Description | Default
+:---------|:------------|:-------
+`Topic` | The Pulsar [topic](reference-terminology.md#topic) on which the reader will establish a subscription and listen for messages 
+`Name` | The name of the reader 
+`StartMessageID` | The initial reader position, i.e. the message at which the reader begins processing messages. The options are `pulsar.EarliestMessage` (the earliest available message on the topic), `pulsar.LatestMessage` (the latest available message on the topic), or a `MessageID` object for a position that isn't earliest or latest. |
+`MessageChannel` | The Go channel used by the reader. Messages that arrive from the Pulsar topic(s) will be passed to this channel. |
+`ReceiverQueueSize` | Sets the size of the reader's receiver queue, i.e. the number of messages that can be accumulated by the reader before the application calls `Next`. A value higher than the default of 1000 could increase reader throughput, though at the expense of more memory utilization. | 1000
+`SubscriptionRolePrefix` | The subscription role prefix. | `reader`
+`ReadCompacted` | If enabled, the reader will read messages from the compacted topic rather than reading the full message backlog of the topic. This means that, if the topic has been compacted, the reader will only see the latest value for each key in the topic, up until the point in the topic message backlog that has been compacted. Beyond that point, the messages will be sent as normal.|
+
+## Messages
+
+The Pulsar Go client provides a `ProducerMessage` interface that you can use to construct messages to producer on Pulsar topics. Here's an example message:
+
+```go
+
+msg := pulsar.ProducerMessage{
+    Payload: []byte("Here is some message data"),
+    Key: "message-key",
+    Properties: map[string]string{
+        "foo": "bar",
+    },
+    EventTime: time.Now(),
+    ReplicationClusters: []string{"cluster1", "cluster3"},
+}
+
+if err := producer.send(msg); err != nil {
+    log.Fatalf("Could not publish message due to: %v", err)
+}
+
+```
+
+The following methods parameters are available for `ProducerMessage` objects:
+
+Parameter | Description
+:---------|:-----------
+`Payload` | The actual data payload of the message
+`Value` | Value and payload is mutually exclusive, `Value interface{}` for schema message.
+`Key` | The optional key associated with the message (particularly useful for things like topic compaction)
+`Properties` | A key-value map (both keys and values must be strings) for any application-specific metadata attached to the message
+`EventTime` | The timestamp associated with the message
+`ReplicationClusters` | The clusters to which this message will be replicated. Pulsar brokers handle message replication automatically; you should only change this setting if you want to override the broker default.
+`SequenceID` | Set the sequence id to assign to the current message
+
+## TLS encryption and authentication
+
+In order to use [TLS encryption](security-tls-transport.md), you'll need to configure your client to do so:
+
+ * Use `pulsar+ssl` URL type
+ * Set `TLSTrustCertsFilePath` to the path to the TLS certs used by your client and the Pulsar broker
+ * Configure `Authentication` option
+
+Here's an example:
+
+```go
+
+opts := pulsar.ClientOptions{
+    URL: "pulsar+ssl://my-cluster.com:6651",
+    TLSTrustCertsFilePath: "/path/to/certs/my-cert.csr",
+    Authentication: NewAuthenticationTLS("my-cert.pem", "my-key.pem"),
+}
+
+```
+
+## Schema
+
+This example shows how to create a producer and consumer with schema.
+
+```go
+
+var exampleSchemaDef = "{\"type\":\"record\",\"name\":\"Example\",\"namespace\":\"test\"," +
+    		"\"fields\":[{\"name\":\"ID\",\"type\":\"int\"},{\"name\":\"Name\",\"type\":\"string\"}]}"
+jsonSchema := NewJsonSchema(exampleSchemaDef, nil)
+// create producer
+producer, err := client.CreateProducerWithSchema(ProducerOptions{
+	Topic: "jsonTopic",
+}, jsonSchema)
+err = producer.Send(context.Background(), ProducerMessage{
+	Value: &testJson{
+		ID:   100,
+		Name: "pulsar",
+	},
+})
+if err != nil {
+	log.Fatal(err)
+}
+defer producer.Close()
+//create consumer
+var s testJson
+consumerJS := NewJsonSchema(exampleSchemaDef, nil)
+consumer, err := client.SubscribeWithSchema(ConsumerOptions{
+	Topic:            "jsonTopic",
+	SubscriptionName: "sub-2",
+}, consumerJS)
+if err != nil {
+	log.Fatal(err)
+}
+msg, err := consumer.Receive(context.Background())
+if err != nil {
+	log.Fatal(err)
+}
+err = msg.GetValue(&s)
+if err != nil {
+	log.Fatal(err)
+}
+fmt.Println(s.ID) // output: 100
+fmt.Println(s.Name) // output: pulsar
+defer consumer.Close()
+
+```

+
+You can use Pulsar C++ client to create Pulsar producers and consumers in C++.
+
+All the methods in producer, consumer, and reader of a C++ client are thread-safe.
+
+## Supported platforms
+
+Pulsar C++ client is supported on **Linux** ,**MacOS** and **Windows** platforms.
+
+[Doxygen](http://www.doxygen.nl/)-generated API docs for the C++ client are available [here](/api/cpp).
+
+
+## Linux
+
+:::note
+
+You can choose one of the following installation methods based on your needs: Compilation, Install RPM or Install Debian.
+
+:::
+
+### Compilation 
+
+#### System requirements
+
+You need to install the following components before using the C++ client:
+
+* [CMake](https://cmake.org/)
+* [Boost](http://www.boost.org/)
+* [Protocol Buffers](https://developers.google.com/protocol-buffers/) >= 3
+* [libcurl](https://curl.se/libcurl/)
+* [Google Test](https://github.com/google/googletest)
+
+1. Clone the Pulsar repository.
+
+```shell
+
+$ git clone https://github.com/apache/pulsar
+
+```
+
+2. Install all necessary dependencies.
+
+```shell
+
+$ apt-get install cmake libssl-dev libcurl4-openssl-dev liblog4cxx-dev \
+  libprotobuf-dev protobuf-compiler libboost-all-dev google-mock libgtest-dev libjsoncpp-dev
+
+```
+
+3. Compile and install [Google Test](https://github.com/google/googletest).
+
+```shell
+
+# libgtest-dev version is 1.18.0 or above
+$ cd /usr/src/googletest
+$ sudo cmake .
+$ sudo make
+$ sudo cp ./googlemock/libgmock.a ./googlemock/gtest/libgtest.a /usr/lib/
+
+# less than 1.18.0
+$ cd /usr/src/gtest
+$ sudo cmake .
+$ sudo make
+$ sudo cp libgtest.a /usr/lib
+
+$ cd /usr/src/gmock
+$ sudo cmake .
+$ sudo make
+$ sudo cp libgmock.a /usr/lib
+
+```
+
+4. Compile the Pulsar client library for C++ inside the Pulsar repository.
+
+```shell
+
+$ cd pulsar-client-cpp
+$ cmake .
+$ make
+
+```
+
+After you install the components successfully, the files `libpulsar.so` and `libpulsar.a` are in the `lib` folder of the repository. The tools `perfProducer` and `perfConsumer` are in the `perf` directory.
+
+### Install Dependencies
+
+> Since 2.1.0 release, Pulsar ships pre-built RPM and Debian packages. You can download and install those packages directly.
+
+After you download and install RPM or DEB, the `libpulsar.so`, `libpulsarnossl.so`, `libpulsar.a`, and `libpulsarwithdeps.a` libraries are in your `/usr/lib` directory.
+
+By default, they are built in code path `${PULSAR_HOME}/pulsar-client-cpp`. You can build with the command below.
+
+ `cmake . -DBUILD_TESTS=OFF -DLINK_STATIC=ON && make pulsarShared pulsarSharedNossl pulsarStatic pulsarStaticWithDeps -j 3`.
+
+These libraries rely on some other libraries. If you want to get detailed version of dependencies, see [RPM](https://github.com/apache/pulsar/blob/master/pulsar-client-cpp/pkg/rpm/Dockerfile) or [DEB](https://github.com/apache/pulsar/blob/master/pulsar-client-cpp/pkg/deb/Dockerfile) files.
+
+1. `libpulsar.so` is a shared library, containing statically linked `boost` and `openssl`. It also dynamically links all other necessary libraries. You can use this Pulsar library with the command below.
+
+```bash
+
+ g++ --std=c++11  PulsarTest.cpp -o test /usr/lib/libpulsar.so -I/usr/local/ssl/include
+
+```
+
+2. `libpulsarnossl.so` is a shared library, similar to `libpulsar.so` except that the libraries `openssl` and `crypto` are dynamically linked. You can use this Pulsar library with the command below.
+
+```bash
+
+ g++ --std=c++11  PulsarTest.cpp -o test /usr/lib/libpulsarnossl.so -lssl -lcrypto -I/usr/local/ssl/include -L/usr/local/ssl/lib
+
+```
+
+3. `libpulsar.a` is a static library. You need to load dependencies before using this library. You can use this Pulsar library with the command below.
+
+```bash
+
+ g++ --std=c++11  PulsarTest.cpp -o test /usr/lib/libpulsar.a -lssl -lcrypto -ldl -lpthread  -I/usr/local/ssl/include -L/usr/local/ssl/lib -lboost_system -lboost_regex -lcurl -lprotobuf -lzstd -lz
+
+```
+
+4. `libpulsarwithdeps.a` is a static library, based on `libpulsar.a`. It is archived in the dependencies of `libboost_regex`, `libboost_system`, `libcurl`, `libprotobuf`, `libzstd` and `libz`. You can use this Pulsar library with the command below.
+
+```bash
+
+ g++ --std=c++11  PulsarTest.cpp -o test /usr/lib/libpulsarwithdeps.a -lssl -lcrypto -ldl -lpthread  -I/usr/local/ssl/include -L/usr/local/ssl/lib
+
+```
+
+The `libpulsarwithdeps.a` does not include library openssl related libraries `libssl` and `libcrypto`, because these two libraries are related to security. It is more reasonable and easier to use the versions provided by the local system to handle security issues and upgrade libraries.
+
+### Install RPM
+
+1. Download a RPM package from the links in the table. 
+
+| Link | Crypto files |
+|------|--------------|
+| [client](@pulsar:dist_rpm:client@) | [asc](@pulsar:dist_rpm:client@.asc), [sha512](@pulsar:dist_rpm:client@.sha512) |
+| [client-debuginfo](@pulsar:dist_rpm:client-debuginfo@) | [asc](@pulsar:dist_rpm:client-debuginfo@.asc),  [sha512](@pulsar:dist_rpm:client-debuginfo@.sha512) |
+| [client-devel](@pulsar:dist_rpm:client-devel@) | [asc](@pulsar:dist_rpm:client-devel@.asc),  [sha512](@pulsar:dist_rpm:client-devel@.sha512) |
+
+2. Install the package using the following command.
+
+```bash
+
+$ rpm -ivh apache-pulsar-client*.rpm
+
+```
+
+After you install RPM successfully, Pulsar libraries are in the `/usr/lib` directory, for example:
+
+```bash
+
+lrwxrwxrwx 1 root root 18 Dec 30 22:21 libpulsar.so -> libpulsar.so.2.9.1
+lrwxrwxrwx 1 root root 23 Dec 30 22:21 libpulsarnossl.so -> libpulsarnossl.so.2.9.1
+
+```
+
+:::note
+
+If you get the error that `libpulsar.so: cannot open shared object file: No such file or directory` when starting Pulsar client, you may need to run `ldconfig` first.
+
+:::
+
+2. Install the GCC and g++ using the following command, otherwise errors would occur in installing Node.js.
+
+```bash
+
+$ sudo yum -y install gcc automake autoconf libtool make
+$ sudo yum -y install gcc-c++
+
+```
+
+### Install Debian
+
+1. Download a Debian package from the links in the table. 
+
+| Link | Crypto files |
+|------|--------------|
+| [client](@pulsar:deb:client@) | [asc](@pulsar:dist_deb:client@.asc), [sha512](@pulsar:dist_deb:client@.sha512) |
+| [client-devel](@pulsar:deb:client-devel@) | [asc](@pulsar:dist_deb:client-devel@.asc),  [sha512](@pulsar:dist_deb:client-devel@.sha512) |
+
+2. Install the package using the following command.
+
+```bash
+
+$ apt install ./apache-pulsar-client*.deb
+
+```
+
+After you install DEB successfully, Pulsar libraries are in the `/usr/lib` directory.
+
+### Build
+
+> If you want to build RPM and Debian packages from the latest master, follow the instructions below. You should run all the instructions at the root directory of your cloned Pulsar repository.
+
+There are recipes that build RPM and Debian packages containing a
+statically linked `libpulsar.so` / `libpulsarnossl.so` / `libpulsar.a` / `libpulsarwithdeps.a` with all required dependencies.
+
+To build the C++ library packages, you need to build the Java packages first.
+
+```shell
+
+mvn install -DskipTests
+
+```
+
+#### RPM
+
+To build the RPM inside a Docker container, use the command below. The RPMs are in the `pulsar-client-cpp/pkg/rpm/RPMS/x86_64/` path.
+
+```shell
+
+pulsar-client-cpp/pkg/rpm/docker-build-rpm.sh
+
+```
+
+| Package name | Content |
+|-----|-----|
+| pulsar-client | Shared library `libpulsar.so` and `libpulsarnossl.so` |
+| pulsar-client-devel | Static library `libpulsar.a`, `libpulsarwithdeps.a`and C++ and C headers |
+| pulsar-client-debuginfo | Debug symbols for `libpulsar.so` |
+
+#### Debian
+
+To build Debian packages, enter the following command.
+
+```shell
+
+pulsar-client-cpp/pkg/deb/docker-build-deb.sh
+
+```
+
+Debian packages are created in the `pulsar-client-cpp/pkg/deb/BUILD/DEB/` path.
+
+| Package name | Content |
+|-----|-----|
+| pulsar-client | Shared library `libpulsar.so` and `libpulsarnossl.so` |
+| pulsar-client-dev | Static library `libpulsar.a`, `libpulsarwithdeps.a` and C++ and C headers |
+
+## MacOS
+
+### Compilation
+
+1. Clone the Pulsar repository.
+
+```shell
+
+$ git clone https://github.com/apache/pulsar
+
+```
+
+2. Install all necessary dependencies.
+
+```shell
+
+# OpenSSL installation
+$ brew install openssl
+$ export OPENSSL_INCLUDE_DIR=/usr/local/opt/openssl/include/
+$ export OPENSSL_ROOT_DIR=/usr/local/opt/openssl/
+
+# Protocol Buffers installation
+$ brew install protobuf boost boost-python log4cxx
+# If you are using python3, you need to install boost-python3 
+
+# Google Test installation
+$ git clone https://github.com/google/googletest.git
+$ cd googletest
+$ git checkout release-1.12.1
+$ cmake .
+$ make install
+
+```
+
+3. Compile the Pulsar client library in the repository that you cloned.
+
+```shell
+
+$ cd pulsar-client-cpp
+$ cmake .
+$ make
+
+```
+
+### Install `libpulsar`
+
+Pulsar releases are available in the [Homebrew](https://brew.sh/) core repository. You can install the C++ client library with the following command. The package is installed with the library and headers.
+
+```shell
+
+brew install libpulsar
+
+```
+
+## Windows (64-bit)
+
+### Compilation
+
+1. Clone the Pulsar repository.
+
+```shell
+
+$ git clone https://github.com/apache/pulsar
+
+```
+
+2. Install all necessary dependencies.
+
+```shell
+
+cd ${PULSAR_HOME}/pulsar-client-cpp
+vcpkg install --feature-flags=manifests --triplet x64-windows
+
+```
+
+3. Build C++ libraries.
+
+```shell
+
+cmake -B ./build -A x64 -DBUILD_PYTHON_WRAPPER=OFF -DBUILD_TESTS=OFF -DVCPKG_TRIPLET=x64-windows -DCMAKE_BUILD_TYPE=Release -S .
+cmake --build ./build --config Release
+
+```
+
+> **NOTE**
+>
+> 1. For Windows 32-bit, you need to use `-A Win32` and `-DVCPKG_TRIPLET=x86-windows`.
+> 2. For MSVC Debug mode, you need to replace `Release` with `Debug` for both `CMAKE_BUILD_TYPE` variable and `--config` option.
+
+4. Client libraries are available in the following places.
+
+```
+
+${PULSAR_HOME}/pulsar-client-cpp/build/lib/Release/pulsar.lib
+${PULSAR_HOME}/pulsar-client-cpp/build/lib/Release/pulsar.dll
+
+```
+
+## Connection URLs
+
+To connect Pulsar using client libraries, you need to specify a Pulsar protocol URL.
+
+Pulsar protocol URLs are assigned to specific clusters, you can use the Pulsar URI scheme. The default port is `6650`. The following is an example for localhost.
+
+```http
+
+pulsar://localhost:6650
+
+```
+
+In a Pulsar cluster in production, the URL looks as follows. 
+
+```http
+
+pulsar://pulsar.us-west.example.com:6650
+
+```
+
+If you use TLS authentication, you need to add `ssl`, and the default port is `6651`. The following is an example.
+
+```http
+
+pulsar+ssl://pulsar.us-west.example.com:6651
+
+```
+
+## Create a producer
+
+To use Pulsar as a producer, you need to create a producer on the C++ client. There are two main ways of using a producer:
+- [Blocking style](#simple-blocking-example) : each call to `send` waits for an ack from the broker.
+- [Non-blocking asynchronous style](#non-blocking-example) : `sendAsync` is called instead of `send` and a callback is supplied for when the ack is received from the broker.
+
+### Simple blocking example
+
+This example sends 100 messages using the blocking style. While simple, it does not produce high throughput as it waits for each ack to come back before sending the next message.
+
+```c++
+
+#include <pulsar/Client.h>
+#include <thread>
+
+using namespace pulsar;
+
+int main() {
+    Client client("pulsar://localhost:6650");
