+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and

+## Function
+DS use registry to do the below three things:
+
+1. Store the metadata of master/worker so that it can get notify when nodes up and down.
+2. Store the metadata of worker to do load balance.
+3. Acquire a global lock when do failover.
+
+So for DS, the registry need to notify the server when the server subscribe data have added/deleted/updated, support a way to create/release a global lock,
+delete the server's metadata when server down.
+
+
+## How to use
+At present, we have implements three registry: Zookeeper(Default),Etcd,Mysql. If you
+want to use them, you should config it at resource/application.yaml. The configuration details
+can be viewed in the README of plugin under Module dolphinscheduler-registry-plugins
+
+## Module
+
+### dolphinscheduler-registry-all
+This module is used for exporting the implemention of registry.
+If you want to add new registry,you should add the dependency in the pom.xml
+
+### dolphinscheduler-registry-api
+This module contains the relevant interfaces involved in the use of the registry.
+The following are several important interfaces
+1. Registry Interface: If you want to implement your own registry, you just need to implement this interface
+2. ConnectionListener Interface: This interface is responsible for the connection status between the client and the registry,
+ The connection state can be viewed in ConnectionState.java
+3. SubscribeListener Interface: This interface is responsible for monitoring the state changes of child nodes under the specified prefix.
+Event content can be viewed in event.java
+
+### dolphinscheduler-registry-plugins
+This module contains all registry implementations in DS

+# Introduction
+
+This module is the etcd registry plugin module, this plugin will use etcd as the registry center.
+
+# How to use
+
+If you want to set the registry center as etcd, you need to set the registry properties in master/worker/api's appplication.yml
+```yaml
+registry:
+ type: etcd
+ endpoints: "http://etcd0:2379, http://etcd1:2379, http://etcd2:2379"
+ # The options below have default values
+ namespace: dolphinscheduler
+ connectionTimeout: 9s
+ # The unit is milliseconds
+ retryDelay: 60ms
+ retryMaxDelay: 300ms
+ retryMaxDuration: 1500ms
+ # The following options are set according to personal needs
+ user: ""
+ password: ""
+ authority: ""
+ loadBalancerPolicy: ""
+```
+
+After do this config, you can start your DolphinScheduler cluster, your cluster will use etcd as registry center to
+store server metadata.

+# Introduction
+
+This module is the zookeeper registry plugin module, this plugin will use zookeeper as the registry center.
+
+# How to use
+
+If you want to set the registry center as zookeeper,you need to set the registry properties in master/worker/api's appplication.yml
+
+```yaml
+registry:
+ type: zookeeper
+ zookeeper:
+ namespace: dolphinscheduler
+ connect-string: localhost:2181
+ retry-policy:
+ base-sleep-time: 60ms
+ max-sleep: 300ms
+ max-retries: 5
+ session-timeout: 30s
+ connection-timeout: 9s
+ block-until-connected: 600ms
+ # The following options are set according to personal needs
+ digest: ~
+```
+
+After do this config, you can start your DolphinScheduler cluster, your cluster will use zookeeper as registry center to
+store server metadata.
