+<p>Sending messages in batch improves performance of delivering small messages.</p>
+
+<h4 id="usage-constraints">Usage constraints</h4>
+<p>Messages of the same batch should have: same topic, same waitStoreMsgOK and no schedule support.</p>
+
+<p>Besides, the total size of the messages in one batch should be no more than 1MiB.</p>
+
+<h4 id="how-to-use-batch">How to use batch</h4>

+<h2 id="broker-role">Broker Role</h2>
+<p>Broker Role is ASYNC_MASTER, SYNC_MASTER or SLAVE.
+If you cannot tolerate message missing, we suggest you deploy SYNC_MASTER and attach a SLAVE to it.
+If you feel ok about missing, but you want the Broker to be always available, you may deploy ASYNC_MASTER with SLAVE.
+If you just want to make it easy, you may only need a ASYNC_MASTER without SLAVE.</p>
+<h2 id="flushdisktype">FlushDiskType</h2>
+<p>ASYNC_FLUSH is recommended, for SYNC_FLUSH is expensive and will cause too much performance loss. If you want reliability, we recommend you use SYNC_MASTER with SLAVE.</p>

+<h2 id="consumer-group-and-subscriptions">Consumer Group and Subscriptions</h2>
+<p>The first thing you should be aware of is that different Consumer Group can consume the same topic independently, and each of them will have their own consuming offsets.
+Please make sure each Consumer within the same Group to subscribe the same topics.</p>
+<h2 id="messagelistener">MessageListener</h2>
+<h3 id="orderly">Orderly</h3>
+<p>The Consumer will lock each MessageQueue to make sure it is consumed one by one in order. This will cause a performance loss, but it is useful when you care about the order of the messages.
+It is not recommended to throw exceptions, you can return ConsumeOrderlyStatus.SUSPEND_CURRENT_QUEUE_A_MOMENT instead.</p>
+<h3 id="concurrently">Concurrently</h3>
+<p>As the name tells, the Consumer will consume the messages concurrently. It is recommended to use this for good performance.
+It is not recommended to throw exceptions, you can return ConsumeConcurrentlyStatus.RECONSUME_LATER instead.</p>
+<h3 id="consume-status">Consume Status</h3>
+<p>For MessageListenerConcurrently, you can return RECONSUME_LATER to tell the consumer that you can not consume it right now and want to reconsume it later. Then you can continue to consume other messages.
+For MessageListenerOrderly, because you care about the order, you can not jump over the message, but you can return SUSPEND_CURRENT_QUEUE_A_MOMENT to tell the consumer to wait for a moment.</p>
+<h3 id="blocking">Blocking</h3>
+<p>It is not recommend to block the Listener, because it will block the thread pool, and eventually may stop the consuming process.</p>
+<h2 id="thread-number">Thread Number</h2>
+<p>The consumer use a ThreadPoolExecutor to process consuming internally, so you can change it by setting setConsumeThreadMin or setConsumeThreadMax.</p>
+<h2 id="consumefromwhere">ConsumeFromWhere</h2>
+<p>When a new Consumer Group is established, it will need to decide whether it needs to consume the historical messages which had already existed in the Broker.
+CONSUME_FROM_LAST_OFFSET will ignore the historical messages, and consume anything produced after that.
+CONSUME_FROM_FIRST_OFFSET will consume every message existed in the Broker.
+You can also use CONSUME_FROM_TIMESTAMP to consume messages produced after the specified timestamp.</p>
+<h2 id="duplication">Duplication</h2>
+<p>Many circumstances could cause duplication, such as:</p>
+<ul>
+ <li>Producer resend messages(i.e, in case of FLUSH_SLAVE_TIMEOUT)</li>
+ <li>Consumer shutdown with some offsets not updated to the Broker in time.</li>
+</ul>
+
+<p>So you may need to do some external work to handle this if your application cannot tolerate duplication. For example, you may check the primary key of your DB.</p>

+
+<p>Management consists of two parts:</p>
+<ul>
+ <li>Brokers periodically renew meta data kept in every name server.</li>
+ <li>Name servers are serving clients, including producers, consumers and command line clients with the latest routing information.</li>
+</ul>
+
+<p>Therefore, before launching brokers and clients, we need to tell them how to reach name servers by feeding them with a name server address list.
+In Apache RocketMQ, this can be done in four ways.</p>
+
+<h2 id="programmatic-way">Programmatic Way</h2>
+
+<p>For brokers, we can specify <code class="highlighter-rouge">namesrvAddr=name-server-ip1:port;name-server-ip2:port</code> in broker configuration file.</p>
+
+<p>For producers and consumers, we can feed name server address list to them as follows:</p>
+
+<div class="language-java highlighter-rouge"><pre class="highlight"><code><span class="n">DefaultMQProducer</span> <span class="n">producer</span> <span class="o">=</span> <span class="k">new</span> <span class="n">DefaultMQProducer</span><span class="o">(</span><span class="s">"please_rename_unique_group_name"</span><span class="o">);</span>
+<span class="n">producer</span><span class="o">.</span><span class="na">setNamesrvAddr</span><span class="o">(</span><span class="s">"name-server1-ip:port;name-server2-ip:port"</span><span class="o">);</span>
+
+<span class="n">DefaultMQPushConsumer</span> <span class="n">consumer</span> <span class="o">=</span> <span class="k">new</span> <span class="n">DefaultMQPushConsumer</span><span class="o">(</span><span class="s">"please_rename_unique_group_name"</span><span class="o">);</span>
+<span class="n">consumer</span><span class="o">.</span><span class="na">setNamesrvAddr</span><span class="o">(</span><span class="s">"name-server1-ip:port;name-server2-ip:port"</span><span class="o">);</span>
+</code></pre>
+</div>
+
+<p>If you use admin command line from shell, you can also specify this way:</p>
+
+<div class="language-bash highlighter-rouge"><pre class="highlight"><code>sh mqadmin <span class="nb">command</span>-name -n name-server-ip1:port;name-server-ip2:port -X OTHER-OPTION
+</code></pre>
+</div>
+
+<p>A simple example is:
+<code class="highlighter-rouge">sh mqadmin -n localhost:9876 clusterList</code>
+assuming to query cluster info on the name server node.</p>
+
+<p>If you have integrated admin tool into your own dashboard, you can:</p>
+
+<div class="language-java highlighter-rouge"><pre class="highlight"><code><span class="n">DefaultMQAdminExt</span> <span class="n">defaultMQAdminExt</span> <span class="o">=</span> <span class="k">new</span> <span class="n">DefaultMQAdminExt</span><span class="o">(</span><span class="s">"please_rename_unique_group_name"</span><span class="o">);</span>
+<span class="n">defaultMQAdminExt</span><span class="o">.</span><span class="na">setNamesrvAddr</span><span class="o">(</span><span class="s">"name-server1-ip:port;name-server2-ip:port"</span><span class="o">);</span>
+</code></pre>
+</div>
+
+<h2 id="java-options">Java Options</h2>
+
+<p>Name server address list may also be fed to your application through specifying the sequel java option
+<code class="highlighter-rouge">rocketmq.namesrv.addr</code> before launching.</p>
+
+<h2 id="environment-variable">Environment Variable</h2>
+
+<p>You can export <code class="highlighter-rouge">NAMESRV_ADDR</code> environment variable. Brokers and clients will examine and use its value if set.</p>
+
+<h2 id="http-endpoint">HTTP Endpoint</h2>
+
+<p>If you do not specify name server address list using previously mentioned methods, Apache RocketMQ will access
+ the following HTTP end point to acquire and update name server address list every two minutes with initial delay of
+ ten seconds.</p>
+

+
+<p>You may override <code class="highlighter-rouge">jmenv.tbsite.net</code> using this Java option: <code class="highlighter-rouge">rocketmq.namesrv.domain</code>,

+
+<p>If you are running Apache RocketMQ in production, this method is recommended because it gives you maximum flexibility

+ <p>The following questions are frequently asked with regard to the RocketMQ project in general.</p>
+
+<h2 id="general">General</h2>
+<h3 id="1-why-did-we-create-rocketmq-project-instead-of-selecting-other-products">1. Why did we create rocketmq project instead of selecting other products?</h3>
+<p>Please refer to <a href="/docs/motivation/">Why RocketMQ</a></p>
+
+<h3 id="2-do-i-have-to-install-other-softewares-such-as-zookeeper-to-use-rocketmq">2. Do I have to install other softewares, such as zookeeper, to use RocketMQ?</h3>
+<p>No. RocketMQ can run independently.</p>
+
+<h2 id="usage">Usage</h2>
+<h3 id="1-where-does-the-newly-created-consumer-id-start-consuming-messages">1. Where does the newly created Consumer ID start consuming messages?</h3>
+
+<ol>
+ <li>If the topic sends a message within three days, then the consumer start consuming messages from the first message saved in the server.</li>
+ <li>If the topic sends a message three days ago, the consumer starts to consume messages from the latest message in the server, in other words, starting from the tail of message queue.</li>
+ <li>If such consumer is rebooted, then it starts to consume messages from the last consumption location.</li>
+</ol>
+
+<h3 id="2-how-to-reconsume-message-when-consumption-fails">2. How to reconsume message when consumption fails?</h3>
+
+<ol>
+ <li>
+ <p>Cluster consumption pattern
+The consumer business logic code returns Action.ReconsumerLater, NULL, or throws an exception, if a message failed to be consumed, it will retry for up to 16 times, after that, the message would be descarded.</p>
+ </li>
+ <li>
+ <p>Broadcast consumption pattern
+The broadcaset consumption still ensures that a message is consumered at least once, but no resend option is provided.</p>
+ </li>
+</ol>
+
+<h3 id="3-how-to-query-the-failed-message-if-there-is-a-consumption-failure">3. How to query the failed message if there is a consumption failure?</h3>
+
+<ol>
+ <li>Using topic query by time, you can query messages within a period of time.</li>
+ <li>Using Topic and Message Id to accurately query the message.</li>
+ <li>Using Topic and Message Key accurately query a class of messages with the same Message Key.</li>
+</ol>
+
+<h3 id="4-are-messages-delivered-exactly-once">4. Are messages delivered exactly once?</h3>
+
+<p>RocketMQ ensures that all messages are delivered at least once. In most cases, the messages are not repeated.</p>
+
+<h3 id="5-how-to-add-a-new-broker">5. How to add a new broker?</h3>
+
+<ol>
+ <li>Start up a new broker and register it to the same list of name servers.</li>
+ <li>By default, only internal system topics and consumer groups are created automatically. If you would like to have your business topic and consumer groups on the new node, please replicate them from the existing broker. Admin tool and command lines are provided to handle this.</li>
+</ol>
+
+<h2 id="configuration-related">Configuration related</h2>
+<p>The following answers are all default values and can be modified by configuration.</p>
+<h3 id="1-how-long-are-the-messages-saved-on-the-server">1. How long are the messages saved on the server?</h3>
+
+<p>Stored messages are will be saved for up to 3 days, and messages that are not consumed for more than 3 days will be deleted.</p>
+
+<h3 id="2-what-is-the-size-limit-for-message-body">2. What is the size limit for message Body?</h3>
+<p>Generally 256KB.</p>
+
+<h3 id="3-how-to-set-the-number-of-consumer-threads">3. How to set the number of consumer threads?</h3>
+<p>When you start Consumer, set a ConsumeThreadNums property, example is as follows:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>consumer.setConsumeThreadMin(20);
+consumer.setConsumeThreadMax(20);
+</code></pre>
+</div>
+
+<h2 id="errors">Errors</h2>
+<h3 id="1-if-you-start-a-producer-or-consumer-failed-and-the-error-message-is-producer-group-or-consumer-repeat">1. If you start a producer or consumer failed and the error message is producer group or consumer repeat?</h3>
+<p>Reason：Using the same Producer /Consumer Group to launch multiple instances of Producer/Consumer in the same JVM may cause the client fail to start.</p>
+
+<p>Solution: Make sure that a JVM corresponding to one Producer /Consumer Group starts only with one Producer/Consumer instance.</p>
+
+<h3 id="2-if-consumer-failed-to-start-loading-json-file-in-broadcast-mode">2. If consumer failed to start loading json file in broadcast mode?</h3>
+<p>Reason: Fastjson version is too low to allow the broadcast consumer to load local offsets.json, causing the consumer boot failure. Damaged fastjson file can also cause the same problem.</p>
+
+<p>Solution: Fastjson version has to be upgraded to rocketmq client dependent version to ensure that the local offsets.json can be loaded. By default offsets.json file is in /home/{user}/.rocketmq_offsets. Or check the integrity of fastjson.</p>
+
+<h3 id="3-what-is-the-impact-of-a-broker-crash">3. What is the impact of a broker crash?</h3>
+
+<ol>
+ <li>Master crashes</li>
+</ol>
+
+<p>Messages can no longer be sent to this broker set, but if you have another broker set available, messages can still be sent given the topic is present. Messages can still be consumed from slaves.</p>
+
+<ol>
+ <li>Some slave crash</li>
+</ol>
+
+<p>As long as there is another working slave, there will be no impact on sending messages. There will also be no impact on consuming messages except when the consumer group is set to consume from this slave preferably. By default, comsumer group consumes from master.</p>
+
+<ol>
+ <li>All slaves crash</li>
+</ol>
+
+<p>There will be no impact on sending messages to master, but, if the master is SYNC_MASTER, producer will get a SLAVE_NOT_AVAILABLE indicating that the message is not sent to any slaves. There will also be no impact on consuming messages except that if the consumer group is set to consume from slave preferably. By default, comsumer group consumes from master.</p>
+
+<h3 id="4-producer-complains-no-topic-route-info-how-to-diagnose">4. Producer complains “No Topic Route Info”, how to diagnose?</h3>
+<p>This happens when you are trying to send messages to a topic whose routing info is not available to the producer.</p>
+
+<ol>
+ <li>Make sure that the producer can connect to a name server and is capable of fetching routing meta info from it.</li>
+ <li>Make sure that name servers do contain routing meta info of the topic. You may query the routing meta info from name server through topicRoute using admin tools or web console.</li>
+ <li>Make sure that your brokers are sending heartbeats to the same list of name servers your producer is connecting to.</li>
+ <li>Make sure that the topic’s permssion is 6(rw-), or at least 2(-w-).</li>
+</ol>
+
+<p>If you can’t find this topic, create it on a broker via admin tools command updateTopic or web console.</p>

+
+<p>The consumer will recieve messages that contains TAGA or TAGB or TAGC. But the limitation is that one message only can have one tag, and this may not work for sophisticated scenarios. In this case, you can use SQL expression to filter out messages.</p>
+
+<h3 id="principle">Principle</h3>
+
+<p>SQL feature could do some calculation through the properties you put in when sending messages. Under the grammars defined by RocketMQ, you can implement some interesting logic. Here is an example:</p>
+
+<pre>
+------------
+| message |
+|----------| a > 5 AND b = 'abc'
+| a = 10 | --------------------> Gotten
+| b = 'abc'|
+| c = true |
+------------
+------------
+| message |
+|----------| a > 5 AND b = 'abc'
+| a = 1 | --------------------> Missed
+| b = 'abc'|
+| c = true |
+------------
+</pre>
+
+<h3 id="grammars">Grammars</h3>
+
+<p>RocketMQ only defines some basic grammars to support this feature. You could also extend it easily.</p>
+
+<ol>
+ <li>Numeric comparison, like <code class="highlighter-rouge">></code>, <code class="highlighter-rouge">>=</code>, <code class="highlighter-rouge"><</code>, <code class="highlighter-rouge"><=</code>, <code class="highlighter-rouge">BETWEEN</code>, <code class="highlighter-rouge">=</code>;</li>
+ <li>Character comparison, like <code class="highlighter-rouge">=</code>, <code class="highlighter-rouge"><></code>, <code class="highlighter-rouge">IN</code>;</li>
+ <li><code class="highlighter-rouge">IS NULL</code> or <code class="highlighter-rouge">IS NOT NULL</code>;</li>
+ <li>Logical <code class="highlighter-rouge">AND</code>, <code class="highlighter-rouge">OR</code>, <code class="highlighter-rouge">NOT</code>;</li>
+</ol>
+
+<p>Constant types are:</p>
+
+<ol>
+ <li>Numeric, like 123, 3.1415;</li>
+ <li>Character, like ‘abc’, must be made with single quotes;</li>
+ <li><code class="highlighter-rouge">NULL</code>, special constant;</li>
+ <li>Boolean, <code class="highlighter-rouge">TRUE</code> or <code class="highlighter-rouge">FALSE</code>;</li>
+</ol>
+
+<h3 id="usage-constraints">Usage constraints</h3>
+
+<p>Only push consumer could select messages by SQL92. The interface is:</p>
+
+<p><code class="highlighter-rouge">public void subscribe(final String topic, final MessageSelector messageSelector)</code></p>
+
+<h3 id="producer-example">Producer example</h3>

+<h1 id="why-rocketmq-">Why RocketMQ ?</h1>
+
+<p>Based on our research, with increased queues and virtual topics in use, ActiveMQ IO module reaches a bottleneck. We
+tried our best to solve this problem through throttling, circuit breaker or degradation, but it did not work well. So
+we begin to focus on the popular messaging solution Kafka at that time. Unfortunately, Kafka can not meet our
+requirements especially in terms of low latency and high reliability, see <a href="/rocketmq/how-to-support-more-queues-in-rocketmq/">here</a> for details.</p>
+
+<p>In this context, we decided to invent a new messaging engine to handle a broader set of use cases, ranging from
+traditional pub/sub scenarios to high volume real-time zero-loss tolerance transaction system. We believe this solution
+can be beneficial, so we would like to open source it to the community. Today, more than 100 companies are using the
+open source version of RocketMQ in their business. We also published a commercial distribution based on RocketMQ, a PaaS
+ product called the <a href="https://intl.aliyun.com/">Alibaba Cloud Platform</a>.</p>
+
+<p>The following table demonstrates the comparison between RocketMQ, ActiveMQ and Kafka (Apache’s most popular messaging solutions according to <a href="https://github.com/akullpp/awesome-java">awesome-java</a>):</p>

ge">TAG</code>, but one message only can own one tag, this is too limited to meet complex business requirements.</p>
+
+<p>So, we want to define and implement a reasonable filter language based on a subset of the SQL 92 expression syntax to support customized message filtering.</p>
+
+<h3 id="why-subset-of-sql92">Why Subset Of SQL92</h3>
+
+<p>Let RocketMQ has the ability of message filtering is the purpose of this issue, and as we know, SQL92 is used widely and most persons are familiar with it.It’s resonable to select it as RocketMQ’s grammar.</p>
+
+<p>As I know, ActiveMQ already impllement this functionality based on JavaCC, it’s simple and exntensible.So I just extract it and integrate into RocketMQ, only some grammars:</p>
+
+<ol>
+ <li>Numeric comparison, like <code class="highlighter-rouge">&gt;</code>, <code class="highlighter-rouge">&gt;=</code>, <code class="highlighter-rouge">&lt;</code>, <code class="highlighter-rouge">&lt;=</code>, <code class="highlighter-rouge">BETWEEN</code>, <code class="highlighter-rouge">=</code>;</li>
+ <li>Character comparison, like <code class="highlighter-rouge">=</code>, <code class="highlighter-rouge">&lt;&gt;</code>, <code class="highlighter-rouge">IN</code>;</li>
+ <li><code class="highlighter-rouge">IS NULL</code> or <code class="highlighter-rouge">IS NOT NULL</code>;</li>
+ <li>Logical <code class="highlighter-rouge">AND</code>, logical <code class="highlighter-rouge">OR</code>, logical <code class="highlighter-rouge">NOT</code>;</li>
+</ol>
+
+<p>Constant type are:</p>
+
+<ol>
+ <li>Numeric, like 123, 3.1415;</li>
+ <li>Character, like ‘abc’, must be maked with single quotes;</li>
+ <li><code class="highlighter-rouge">NULL</code>, special constant;</li>
+ <li>Boolean, <code class="highlighter-rouge">TRUE</code> or <code class="highlighter-rouge">FALSE</code>;</li>
+</ol>
+
+<h3 id="design">Design</h3>
+<ul>
+ <li>Structure</li>
+</ul>
+
+<p><img src="/assets/images/blog/filter_structure_apach.png" alt="screenshot" /></p>
+
+<ol>
+ <li>Broker collects the expression of consumer through heartbeat request, and saved in <code class="highlighter-rouge">ConsumerFilterManager</code>.</li>
+ <li>When consumer pulls messages, broker will construct a <code class="highlighter-rouge">MessageFilter</code>(an interface) with compiled expression and subscription data to select matched messages in <code class="highlighter-rouge">CommitLog</code>.</li>
+</ol>
+
+<p>The main logic is simple.</p>
+
+<ul>
+ <li>New Module, rocketmq-filter</li>
+</ul>
+
+<p>The implementation of SQL92 language is placed in this module which have dependency on common module.</p>
+
+<p>Broker compile or evaluate expression through the interface of <code class="highlighter-rouge">FilterSpi</code> contained in <code class="highlighter-rouge">FilterFactory</code> that manage all <code class="highlighter-rouge">FilterSpi</code> and also support new one to register.</p>
+
+<ul>
+ <li>How to manage consumer’s expression data</li>
+</ul>
+
+<p>Different from tag filtering, expression of SQL92 should be compiled first to check whether is leagal and then use the complied expression to compute. This procedure is designed to take place at broker.</p>
+
+<p><code class="highlighter-rouge">ConsumerManager</code> manage the suscriptions of push consumer, and <code class="highlighter-rouge">ConsumerFilterManager</code> manage the expression info of push consumer who wish to filter message by special language, the info includes data version, expression, compiled expression, alive time and etc.</p>
+
+<ul>
+ <li>How to filter message by expression</li>
+</ul>
+
+<p>I redesign the interface <code class="highlighter-rouge">getMessage</code> of <code class="highlighter-rouge">MessageStore</code> by replace the last parameter <code class="highlighter-rouge">SubscriptionData</code> to <code class="highlighter-rouge">MessageFilter</code> that is also refactored. The purpose is to make module <code class="highlighter-rouge">rocketmq-store</code> has no relation with protocol.</p>
+
+<p>When get message, the implementation <code class="highlighter-rouge">ExpressionMessageFilter</code> would check whether the message is matched by <code class="highlighter-rouge">BitsArray</code> which will be refered later or evaluation, just as the mechanism of tag filtering.</p>
+
+<ul>
+ <li>Optimization, pre-calculate the filtering result when build consume queue</li>
+</ul>
+
+<p>It’s poor performance to do filter when pull message:</p>
+
+<ol>
+ <li>off-heap to heap, once every consumer subscribed same topic pull message.</li>
+ <li>decode message properties, once every consumer subscribed same topic pull message.</li>
+</ol>
+
+<p><code class="highlighter-rouge">BloomFilter</code> and pre-calculation are adopted to optimize the situation:</p>
+
+<p><img src="/assets/images/blog/filter_build_cq_apache.png" alt="screenshot" /></p>
+
+<ol>
+ <li>Every consumer has been asigned some bit position of <code class="highlighter-rouge">BloomFilter</code> when register to broker.</li>
+ <li>When broker build queue after message into <code class="highlighter-rouge">CommitLog</code>, the consumer’s filtering result would be calculated, and all resuls are assembled as a <code class="highlighter-rouge">BitsArray</code> saved in <code class="highlighter-rouge">ConsumeQueueExt</code>.</li>
+ <li><code class="highlighter-rouge">ConsumeQueueExt</code> is a store file linked to <code class="highlighter-rouge">ConsumeQueue</code>, <code class="highlighter-rouge">ConsumeQueue</code> could find the data by the <code class="highlighter-rouge">tagsCode</code> whitch is already replaced by the address(for compitable, the range is Long.MIN_VALUE to Integer.MIN_VALUE) generated by <code class="highlighter-rouge">ConsumeQueueExt</code>.</li>
+ <li><code class="highlighter-rouge">ExpressionMessageFilter</code> could use the <code class="highlighter-rouge">BitsArray</code> to check whether the message is matched. Because of BloomFilter’s collision, it also need to decode properties to do calculation for matched message(may could be reduced by check the collision, not include in this edition).</li>
+</ol>
+
+<p>This optimization is suitable for:</p>
+
+<ol>
+ <li>High subscription ratio.</li>
+ <li>Large properties.</li>
+</ol>
+
+<p>This optimization is off default, it need set some configs when broker starting to switch on:</p>
+
+<ol>
+ <li>enableCalcFilterBitMap = true, means to caculate bitmap when build consume queue.</li>
+ <li>expectConsumerNumUseFilter = XX(Integer, default is 32), means estimated consumer num subscribe same topic.</li>
+ <li>maxErrorRateOfBloomFilter = XX(1~100, default is 20), means error rate of bloom filter.</li>
+ <li>enableConsumeQueueExt = true, means construct consume queue extend file.</li>
+</ol>
+
+<h3 id="interface">Interface</h3>
+
+<p>Only push consumer could filter message by SQL92 expression in this edition, the interface is:</p>
+
+<p><code class="highlighter-rouge">public void subscribe(final String topic, final MessageSelector messageSelector)</code></p>
+
+<h3 id="performance-comparison">Performance Comparison</h3>
+
+<p>Configuration of broker machine: 32 core, 128G memory, 1000Mb/s full duplex dual network</p>
+
+<p>Producer send message with 1k body and 1k properties.</p>
+
+<p>Five consumers consume message through push model, every consumer would get 1/5 messages of total.</p>
+
+<p>Cpu and gc frequency is about 30% lower when do pre-calculate filtering result.</p></content><author><name>{"name"=>nil, "avatar"=>"/assets/images/rmq-logo.png", "bio"=>"A fast, low latency, reliable, scalable, distributed MOM.", "location"=>"Hangzhou, China", "email"=>"dev@rocketmq.incubator.apache.org", "uri"=>"http://incubator.staging.apache.org/projects/rocketmq.html", "bitbucket"=>nil, "codepen"=>nil, "dribbble"=>nil, "flickr"=>nil, "facebook"=>nil, "foursquare"=>nil, "github"=>"apache/incubator-rocketmq", "google_plus"=>nil, "keybase"=>nil, "instagram"=>nil, "lastfm"=>nil, "linkedin"=>nil, "pinterest"=>nil, "soundcloud"=>nil, "stackoverflow&q

+<h3 id="prepare-the-repo">Prepare the repo</h3>
+<ul>
+ <li>fork the apache repo on Github
+<img src="http://img3.tbcdn.cn/5476e8b07b923/TB17G5kQpXXXXcUapXXXXXXXXXX" alt="" />
+Click the “fork” button, a forked repo will be added to your repo list.</li>
+ <li>clone the forked repo, here take “foo” as example
+ <blockquote>
+ <p>git clone https://github.com/foo/incubator-rocketmq.git</p>
+ </blockquote>
+ </li>
+ <li>add apache remote repo
+ <blockquote>
+ <p>git remote add apache https://github.com/apache/incubator-rocketmq.git</p>
+ </blockquote>
+ </li>
+ <li>show the remote repos
+ <blockquote>
+ <p>git remote -v<br />
+apache https://github.com/apache/incubator-rocketmq.git (fetch)<br />
+apache https://github.com/apache/incubator-rocketmq.git (push)<br />

+ </blockquote>
+ </li>
+</ul>
+
+<p><strong>Note</strong>: https://github.com/apache/incubator-rocketmq.git is a read-only repo, mirrored from git://git.apache.org/incubator-rocketmq.git. For submitting PR, fork this read-only repo on Github is OK.</p>
+
+<h3 id="use-a-new-branch-to-write-your-own-code-and-commit">Use a new branch to write your own code and commit</h3>
+<p>you’d better use a new branch for each PR, for it is convenient to manage your code and commits</p>
+<blockquote>
+ <p>git checkout -b new_pr<br />
+//do something and commit</p>
+</blockquote>
+
+<h3 id="important-rebase-instead-of-merge">[Important] Rebase instead of merge</h3>
+<blockquote>
+ <p>git fetch apache<br />
+git rebase apache/develop</p>
+</blockquote>
+
+<p>Note: if using merge, it will dirty the commits</p>
+
+<p>the difference between rebase and merge can refer to:<br />
+<a href="https://www.atlassian.com/git/tutorials/merging-vs-rebasing">https://www.atlassian.com/git/tutorials/merging-vs-rebasing</a></p>
+
+<h3 id="suggestedsquash-the-commits">[Suggested]Squash the commits</h3>
+<p>you can code and commit as usual. But when you think it is time to submit a PR, it is better to squash your commits into single one, for that others can easily identify your PR from the history commits.
+you can squash as follows:</p>
+<blockquote>
+ <p>gt reset &lt;the latest commit that dose not belong to you PR&gt;<br />
+git add –all<br />
+git commit -m “attach the issue or jira”<br />
+git push (if the commits have been already pushed to your remote repo, git push will fail , use git push -f instead)</p>
+</blockquote>
+
+<p>For example:</p>
+<blockquote>
+ <p>git log</p>
+</blockquote>
+
+<p><img src="https://lh3.googleusercontent.com/-xYoltD_ZDhE/WNTONuq58WI/AAAAAAAAABo/zWZdGVxNVa8/I/14864352604541.jpg" alt="" /></p>
+
+<blockquote>
+ <p>git resset b4108d2d9d3b1522e45ac5e7ea37106f2135bfa0 <br />
+git commit -m ‘Add batch feature’<br />
+git log</p>

+<blockquote>
+ <p>git push</p>
+</blockquote>
+
+<h3 id="attach-jira-or-issue">Attach jira or issue</h3>
+<p>For now, we have finished the preparations of a PR. It is time to create it. For apache projects, we could attach the jira issue using specific title like “[XXX] add something”, such as “[ROCKETMQ-80] Add batch feature”, the “XXX” represents the the name of the jira issue.

" xml:base="/rocketmq/four-methods-to-feed-name-server-address-list/"><p>In Apache RocketMQ, name servers are designed to coordinate each component of the distributed system
+and fulfill much of this responsibility through managing topic route information.</p>
+
+<p>The management, roughly speaking, consists two parts:</p>
+<ul>
+ <li>Brokers periodically renew meta data, including topics they have, which are kept in every name servers.</li>
+ <li>Name servers are serving clients, including producers, consumers and command line clients with the latest routing information.</li>
+</ul>
+
+<p>Therefore, before launching brokers and clients, we need to tell them how to reach name servers by feeding them with a name server address list.
+In Apache RocketMQ, this can be done in four ways.</p>
+
+<ol>
+ <li>
+ <p>Programmatic Way</p>
+
+ <p>For broker, we may specify <code class="highlighter-rouge">namesrvAddr=name-server-ip1:port;name-server-ip2:port</code> in broker configuration file.</p>
+
+ <p>For producers and consumers, we may feed name server address list to them as follows:</p>
+
+ <p><code class="highlighter-rouge">
+DefaultMQProducer producer = new DefaultMQProducer("please_rename_unique_group_name");
+producer.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+
+ <p><code class="highlighter-rouge">
+DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("please_rename_unique_group_name");
+consumer.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+
+ <p>If you use admin command line from shell, you may specify this way:
+<code class="highlighter-rouge">sh mqadmin command-name -n name-server-ip1:port;name-server-ip2:port -X OTHER-OPTION</code></p>
+
+ <p>a simple example is:
+<code class="highlighter-rouge">sh mqadmin -n localhost:9876 clusterList</code>
+assuming to query cluster info on the name server node.</p>
+
+ <p>If integrating admin tool into your own dashboard, you may
+<code class="highlighter-rouge">DefaultMQAdminExt defaultMQAdminExt = new DefaultMQAdminExt("please_rename_unique_group_name");
+ defaultMQAdminExt.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+ </li>
+ <li>
+ <p>Java Options</p>
+
+ <p>Name server address list may also be fed to your application through specifying the sequel java option
+ <code class="highlighter-rouge">rocketmq.namesrv.addr</code> before launching.</p>
+ </li>
+ <li>
+ <p>Environment Variable</p>
+
+ <p>You can export <code class="highlighter-rouge">NAMESRV_ADDR</code> environment variable. Brokers and clients will examine and use its value if set.</p>
+ </li>
+ <li>
+ <p>HTTP Endpoint</p>
+
+ <p>If you do not specify name server address list using previously mentioned methods, Apache RocketMQ will access
+ the following HTTP end point to acquire and update name server address list every two minutes with initial delay of
+ ten seconds.</p>
+
+ <p>On default, the end point is:</p>
+
+ <p><code class="highlighter-rouge">http://jmenv.tbsite.net:8080/rocketmq/nsaddr</code></p>
+
+ <p>You may override <code class="highlighter-rouge">jmenv.tbsite.net</code> by this java option: <code class="highlighter-rouge">rocketmq.namesrv.domain</code>,
+ You may also override <code class="highlighter-rouge">nsaddr</code> part by this java option: <code class="highlighter-rouge">rocketmq.namesrv.domain.subgroup</code></p>
+
+ <p>If you are running Apache RocketMQ in production, this method is recommended because it gives you maximum flexibility
+ – you can dynamically add or remove name server nodes without necessity of rebooting your brokers and clients
+ according to your name servers’ system load.</p>
+ </li>
+</ol>
+
+<ul>
+ <li>
+ <p>Priority</p>
+
+ <p>Methods introduced first take precedence over the latter, namely, <br />
+ <code class="highlighter-rouge">Programmatic Way &gt; Java Options &gt; Environment Variable &gt; HTTP Endpoint</code></p>
+ </li>

+<h1 id="compatibility">Compatibility</h1>
+
+<p>what is compatibility？it is also the key to understanding the compatible dependency.Compatibility, often catch our eyes through two forms,<strong>binary compatibility</strong>,that means they can run the same executable code, typically machine code for a general purpose computer CPU.within the framework of Release-to-Release Binary Compatibility in SOM (Forman, Conner, Danforth, and Raper, Proceedings of OOPSLA ‘95), Java programming language binaries are binary compatible under all relevant transformations that the authors identify (with some caveats with respect to the addition of instance variables). here is a list of some important binary compatible changes that the Java programming language supports:</p>
+
+<ul>
+ <li>Reimplementing existing methods, constructors, and initializers to improve performance.</li>
+ <li>Changing methods or constructors to return values on inputs for which they previously either threw exceptions that normally should not occur or failed by going into an infinite loop or causing a deadlock.</li>
+ <li>Adding new fields, methods, or constructors to an existing class or interface.</li>
+ <li>Deleting private fields, methods, or constructors of a class.</li>
+ <li>When an entire package is updated, deleting default (package-only) access fields, methods, or constructors of classes and interfaces in the package.</li>
+ <li>Reordering the fields, methods, or constructors in an existing type declaration.</li>
+ <li>Moving a method upward in the class hierarchy.</li>
+ <li>Reordering the list of direct superinterfaces of a class or interface.</li>
+ <li>Inserting new class or interface types in the type hierarchy.</li>
+</ul>
+
+<p>Generally,java language is <strong>upwards binary-compatible</strong> with previous version,such as Java SE 6 is upwards binary-compatible with J2SE 5.0 except for some minor incompatibilities.You can get details from <a href="http://www.oracle.com/technetwork/java/javase/compatibility-137541.html#binary">here</a>.</p>
+
+<p>Another compatibility form,we call it <strong>source compatibility</strong>,meaning that recompilation is necessary.Java language does not support downward source compatibility. Such as if source files use new language features or Java SE platform APIs, they will not be usable with an earlier version of the Java platform. Usually it will throw similar error like this:</p>
+
+<div class="language-java highlighter-rouge"><pre class="highlight"><code><span class="n">java</span><span class="o">.</span><span class="na">lang</span><span class="o">.</span><span class="na">UnsupportedClassVersionError</span><span class="o">:</span> <span class="n">com</span><span class="o">.</span><span class="na">alibaba</span><span class="o">.</span><span class="na">mq</span><span class="o">.</span><span class="na">core</span><span class="o">.</span><span class="na">MessageConsumer</span> <span class="o">:</span>

+</code></pre>
+</div>
+
+<p>Java language source compatibility policy is as follows,except for any incompatibilities listed further below:</p>
+
+<ul>
+ <li>Maintenance releases (such as 1.7.25, 1.7.26) do not introduce any new language features or APIs. They will maintain source-compatibility with each other.</li>
+ <li>Functionality releases and major releases (such as 1.4.0,5.0,6.0,7.0,8.0) maintain upwards but not downwards source-compatibility.</li>
+</ul>
+
+<p>Let’s sum up before going on:</p>
+
+<ul>
+ <li>Document those incompatibility cases as much as possible, even some rare circumstances and corner cases.</li>
+ <li>Recommend developer to provide facilities that alert developers to the impact of changes on pre-existing binaries that cannot be recompiled.</li>
+ <li>Generally speaking,Binary Compatibility problems may occur in the following situations:</li>
+ <li><strong>Replacing the old with the new</strong>,such as the Java platform Profiling Architecture in the Java SE6,JVMDI was removed and JVMPI was disabled in Java SE 6.</li>
+ <li><strong>Combinatorial resolution</strong>,such as Non class files have been moved from rt.jar in Java SE 6.if -Xbootclasspath:<path to="" rt.jar=""> is specified,and request any resource files will fail since these resources now reside in a different jar file called resources.jar.</path></li>
+ <li><strong>Behavior change</strong>,such as Java SE 6 will throw an OverlappingFileLockException,if the application attempts to lock the overlapping region other instances of FileChannel that has been locked, in order to realize the backward compatibility, it provides disableSystemWideOverlappingFileLockCheck system properties. again, also in Java SE 6, jar will preserve file modification dates and times during extract, through the sun.tools.jar.useExtractionTime=true to achieve backward compatibility.</li>
+ <li><strong>Structure change</strong>,this is also the key problem to solve in <strong>Dependency Mediator</strong> project. generally speaking,modification and deletion belonging to incompatible operations.and more attentions must be paid in the RPC service maintenance, more detailed description,please refer to an <a href="http://blog.csdn.net/fengjia10/article/details/7799227">article</a> I wrote before. also you can read the the thirteenth chapter of Java language specification.</li>
+</ul>
+
+<h1 id="component-compatible-dependency">Component Compatible Dependency</h1>
+
+<p>This article don’t talk about <strong>dependency analysis</strong> and <strong>dependency decoupling</strong>,if you care these topics,please read <a href="http://java.dzone.com/articles/dependency-analysis-and-1">Dependency Analysis and the Modularisation of Java Programs</a>.highly recommending you try to dive into open source project <a href="http://xplrarc.massey.ac.nz/">Architecture Explorer</a>,through bcel technology,analyzing and measuring component’s dependency relationship.but in my opinion,<a href="http://clarkware.com/software/JDepend.html">Jdepend</a> was surely the most distinguished tool in dependency analysis and dependency decoupling area.it traverses Java class file directories and generates design quality metrics for each Java package,also allows you to automatically measure the quality of a design in terms of its extensibility, reusability, and maintainability
to manage package dependencies effectively.</p>
+
+<p>Let’s return,ask yourself，have you ever been disturbed by the following problems?</p>
+
+<ul>
+ <li>Your service depend a volatile service,volatile means your service depending neither an abstract class nor a interface,this class update at irregular intervals,you often encountered errors such as <strong>NoSuchMethodError</strong>,<strong>NoSuchFieldError</strong> and <strong>NoClassDefFoundError</strong> etc.</li>
+ <li>You are developing a new feature,but this feature can not backward compatible with previous version,
+what should you do ? How do you give a incompatible list in your release report.</li>
+ <li>Java language library is a superb collection of beautiful things,how do you make a rational dependency exclusion and effective mediate various dependency problems when developing.</li>
+</ul>
+
+<p>It is the time to introduce the key idea - <strong>Mediating Components Compatible Dependency</strong>.Specifically,it includs the following basic principles:</p>
+
+<ul>
+ <li>Interface-oriented programming</li>
+ <li>Single component signature protection</li>
+ <li>Single component compatibility protection</li>
+ <li>Multi-component compatibility compile time checking</li>
+</ul>
+
+<h2 id="interface-oriented-programming">Interface-oriented programming</h2>
+
+<p>Interface-oriented programming,It’s easier said than done.I will cite SLF4J design philosophy explain this principle.</p>
+
+<p>Differing from commons logging,SLF4J use <strong>static binder technology</strong> so as to avoid notorious <a href="http://articles.qos.ch/classloader.html">classloader problem</a>,every concrete log implementation must
+have a class named StaticLoggerBinder and implementing SLF4J spi LoggerFactoryBinder.thus you just depend SLF4J api,not concerned about underlying implementation.some people may asking,why choose SLF4J not commons logging，I can also depend commons logging api but not concret implementation？it’s not performance but classloader problem.JCL discovery process relies on classloader hacks to find the logging framework at runtime but this mechanism leads to numerous problems including unexpected behavior,hard to debug classloading problems resulting in increased complexity.This is nicely captured by Ceki (the author of Log4J, SLF4J and Logback) in Think again before adopting the commons-logging API (which also mentions memory leaks problems observed with JCL).and this is why SLF4J, which uses static bindings, has been created. Let’s see.how to find the concrete realizations in SLF4J:</p>

+<h2 id="sendstatus">SendStatus</h2>
+<p>When sending a message, you will get SendResult which contains SendStatus. Firstly, we assume that Message’s isWaitStoreMsgOK=true(default is true). If not, we will always get SEND_OK if no exception is thrown.
+Below is a list of descriptions about each status:</p>
+<h3 id="flush_disk_timeout">FLUSH_DISK_TIMEOUT</h3>
+<p>If the Broker set MessageStoreConfig’s FlushDiskType=SYNC_FLUSH(default is ASYNC_FLUSH), and the Broker doesn’t finish flushing the disk within MessageStoreConfig’s syncFlushTimeout(default is 5 secs), you will get this status.</p>
+<h3 id="flush_slave_timeout">FLUSH_SLAVE_TIMEOUT</h3>
+<p>If the Broker’s role is SYNC_MASTER(default is ASYNC_MASTER), and the slave Broker doesn’t finish synchronizing with the master within the MessageStoreConfig’s syncFlushTimeout(default is 5 secs), you will get this status.</p>
+<h3 id="slave_not_available">SLAVE_NOT_AVAILABLE</h3>
+<p>If the Broker’s role is SYNC_MASTER(default is ASYNC_MASTER), but no slave Broker is configured, you will get this status.</p>
+<h3 id="send_ok">SEND_OK</h3>
+<p>SEND_OK does not mean it is reliable. To make sure no message would be lost, you should also enable SYNC_MASTER or SYNC_FLUSH.</p>
+<h3 id="duplication-or-missing">Duplication or Missing</h3>
+<p>If you get FLUSH_DISK_TIMEOUT, FLUSH_SLAVE_TIMEOUT and the Broker happens to shutdown right the moment, you can find your message missing.
+At this time, you have two choices, one is to let it go, which may cause this message to be lost; another is to resend the message, which may get message duplication.
+Often we suggest resend and find a way to handle the duplication removal when consuming. Unless you feel it doesn’t matter when some messages are lost.
+But keep in mind that resending is useless when you get SLAVE_NOT_AVAILABLE. If this happens, you should keep the scene and alert the Cluster Manager.</p>
+<h2 id="timeout">Timeout</h2>
+<p>The Client sends requests to Broker, and wait for the responses, but if the max wait time has elapsed and no response is returned, the Client will throw a RemotingTimeoutException.
+The default wait time is 3 seconds. You can also pass timeout argument using send(msg, timeout) instead of send(msg).
+Note that we do not suggest the wait time to be too small, as the Broker needs some time to flush the disk or synchronize with slaves. Also the value may have little effect if it exceeds syncFlushTimeout by a lot as Broker may return a response with FLUSH_SLAVE_TIMEOUT or FLUSH_SLAVE_TIMEOUT before the timeout.</p>
+<h2 id="message-size">Message Size</h2>
+<p>We suggest the size of message should be no more than 512K.</p>
+<h2 id="async-sending">Async Sending</h2>
+<p>Default send(msg) will block until the response is returned. So if you care about performance, we suggest you use send(msg, callback) which will act in the async way.</p>
+<h2 id="producer-group">Producer Group</h2>
+<p>Normally, the producer group has no effects. But if you are involved in a transaction, you should pay attention to it.
+By default, you can only create only one producer with the same producer group in the same JVM, which is usually enough.</p>
+<h2 id="thread-safety">Thread Safety</h2>
+<p>The producer is thread-safe, you can just use it in your business solution.</p>
+<h2 id="performance">Performance</h2>
+<p>If you want more than one producer in one JVM for big data processing, we suggest:</p>
+<ul>
+ <li>use async sending with a few producers (3~5 is enough)</li>
+ <li>setInstanceName for each producer</li>
+</ul>

+
+<h1 id="introduction">Introduction</h1>
+
+<p>This section is to introduce deployment solution that may be considered production ready. Generally speaking, we are deploying a resilient RocketMQ cluster having no single point of failure.</p>
+
+<h1 id="name-server">Name Server</h1>
+
+<p>To ensure the cluster can still operate normally when name server instance crashes, two or more name server instances are recommended. As long as there is one name server instance alive, the whole cluster remains serving.</p>
+
+<p>Name server follows share-nothing design paradigm. Brokers send heartbeat data to all name servers. Producers and consumers may query meta data from any one of name servers available while sending / consuming messages.</p>
+
+<h1 id="broker">Broker</h1>
+
+<p>Brokers can be divided into two categories according to their roles: master and slave. Master brokers can read and write while slave brokers can only read messages replicated from master. Master brokers have brokerID=0; brokerID of slave is non-zero.</p>
+
+<p>Brokers may also be grouped by the brokerName property. Slave brokers find their master through brokerName. One master broker along with zero, one or multiple slave brokers is called a broker set.</p>
+
+<p>In serious scenarios, we should have at least two broker sets. Each topic, as you guess, resides in two or more broker sets.</p>
+
+<h1 id="disk-flush-type-sync_flush--async_flush">Disk Flush Type: SYNC_FLUSH / ASYNC_FLUSH</h1>
+
+<p>Each broker can be configured to be sync or async in terms of IO flushing strategy. To put it simply, if your business tolerates none message loss at extreme scenarios like OS crash or power loss, SYNC_FLUSH mode is recommended. Broker of SYNC_FLUSH mode would flush each message it receives onto disk before acknowledging producer. Obviously, throughout of this mode is highly dependent on IOPS of your hard disk.</p>
+
+<p>Broker of ASYNC_FLUSH mode, on the other hand, takes advantage of group-committing: only flushes dirty page caches to disk periodically or when count of dirty page caches reaches certain amount. Hence, the latter yields better performance.</p>
+
+<h1 id="replication-sync--async-broker">Replication: Sync / Async Broker</h1>
+
+<p>Similar to many replication system, sync brokers await until commit log is replicated to a slave before acknowledging. Async brokers, instead, return immediately after messages are processed on master.</p>
+
+<h1 id="configuration">Configuration</h1>
+
+<p>There are three pre-built configurations shipped with the distribution of RocketMQ under conf folder for your reference:</p>
+
+<ol>
+ <li>2m-2s-sync</li>
+ <li>2m-2s-async</li>
+ <li>2m-noslave</li>
+</ol>
+
+<p>Note: all configurations uses ASYNC_FLUSH.</p>
+
+<h1 id="deployment-example">Deployment Example</h1>
+
+<p>For example, We want to have a cluster with 2 name servers, 2 broker sets with general purpose:
+for this example, we choose <code class="highlighter-rouge">2m-2s-sync</code>
+Assuming binary RocketMQ is at <code class="highlighter-rouge">/home/rocketmq/dist</code></p>
+
+<ol>
+ <li>
+ <p>Start up two name servers as is shown in Quick Start guide. Assume their IPs are 192.168.0.2 and 192.168.0.3.</p>
+ </li>
+ <li>
+ <p>Start brokers</p>
+
+ <p><code class="highlighter-rouge">cd /home/rocketmq/dist/bin</code></p>
+
+ <p><code class="highlighter-rouge">bash mqbroker -c ../conf/2m-2s-sync/broker-a.properties -n 192.168.0.2:9876,192.168.0.3:9876</code></p>
+
+ <p><code class="highlighter-rouge">bash mqbroker -c ../conf/2m-2s-sync/broker-a-s.properties -n 192.168.0.2:9876,192.168.0.3:9876</code></p>
+
+ <p><code class="highlighter-rouge">bash mqbroker -c ../conf/2m-2s-sync/broker-b.properties -n 192.168.0.2:9876,192.168.0.3:9876</code></p>

+ </li>
+ <li>
+ <p>Verify</p>
+
+ <p>Execute the following command to verify</p>
+

+
+<p>This is a guide to make a released version of Apache RocketMQ (incubating). Please follow the steps below:</p>
+
+<h2 id="preliminaries">Preliminaries</h2>
+<h3 id="apache-release-documentation">Apache Release Documentation</h3>
+<p>The release documentations provided by The ASF can be found here:</p>
+
+<ul>
+ <li><a href="http://www.apache.org/dev/release-publishing">Apache Release Guide</a></li>
+ <li><a href="http://www.apache.org/dev/release.html">Apache Release Policy</a></li>

+ <li><a href="http://www.apache.org/dev/publishing-maven-artifacts.html">Maven Release Info</a></li>
+</ul>
+
+<h3 id="code-signing-key">Code Signing Key</h3>
+<p>Create a code signing gpg key for release signing, use <strong><your Apache ID>@apache.org</strong> as your primary ID for the code signing key. See <a href="https://www.apache.org/dev/release-signing">Apache Release Signing documentation</a> for more details.</p>
+
+<ul>
+ <li>Create new pgp key. Please refer to <a href="http://www.apache.org/dev/openpgp.html">here</a> on how to use gpg key.</li>
+ <li>Generate a new key via <code class="highlighter-rouge">gpg --gen-key</code>, and answer 4096 bits with no expiration time.</li>
+ <li>Upload your key to a public key server by <code class="highlighter-rouge">gpg --keyserver pgpkeys.mit.edu --send-key <your key id></code>.</li>
+ <li>Get the key signed by other committers(Optional).</li>
+ <li>Add the key to the RocketMQ <a href="https://dist.apache.org/repos/dist/dev/incubator/rocketmq/KEYS">KEYS file</a>.</li>
+</ul>
+
+<p><strong>Tips:</strong> If you have more than one key in your gpg, set the code signing key to <code class="highlighter-rouge">~/.gnupg/gpg.conf</code> as default key is recommended.</p>
+
+<h3 id="prepare-your-maven-settings">Prepare Your Maven Settings</h3>
+<p>Make sure your Maven settings.xml file contains the following:</p>
+
+<div class="language-xml highlighter-rouge"><pre class="highlight"><code><span class="nt"><settings></span>
+ <span class="nt"><profiles></span>

+
+<p><strong>Tips:</strong> It is highly recommended to use <a href="http://maven.apache.org/guides/mini/guide-encryption.html">Maven’s password encryption capabilities</a> for your passwords.</p>
+
+<h3 id="cleanup-jira-issues">Cleanup JIRA issues</h3>
+<p>Cleanup JIRA issues related to this release version, and check all the issues has been marked with right version in the <code class="highlighter-rouge">FixVersion</code> field.</p>
+
+<h3 id="publish-the-release-notes">Publish the Release Notes</h3>
+<p>Generate the release notes via <a href="https://issues.apache.org/jira/browse/ROCKETMQ/">RocketMQ JIRA</a> and publish it to the <a href="https://github.com/apache/incubator-rocketmq-site">rocketmq-site</a>, there is a <a href="http://rocketmq.incubator.apache.org/release_notes/release-notes-4.0.0-incubating/">release notes</a> of <code class="highlighter-rouge">4.0.0-incubating</code> available for reference, include the link to the release notes in the voting emails.</p>
+
+<h2 id="build-the-release-candidate">Build the Release Candidate</h2>
+<p>Firstly, checkout a new branch from <code class="highlighter-rouge">master</code> with its name equal to the release version, like <code class="highlighter-rouge">release-4.0.0-incubating</code>.</p>
+
+<h3 id="build-the-candidate-release-artifacts">Build the Candidate Release Artifacts</h3>
+<p>Before building the release artifacts, do some verifications below:</p>
+
+<ul>
+ <li>Make sure that your are in the candidate release branch.</li>
+ <li>Make sure that all the unit tests can pass via <code class="highlighter-rouge">mvn clean install</code>.</li>
+ <li>Make sure that all the integration tests can pass via <code class="highlighter-rouge">mvn clean test -Pit-test</code>.</li>
+</ul>
+
+<p>Perform the following to generate and stage the artifacts:</p>
+
+<ol>
+ <li><code class="highlighter-rouge">mvn clean release:clean</code></li>
+ <li><code class="highlighter-rouge">mvn release:prepare -Psigned_release -Darguments="-DskipTests"</code>, answer the correct release version, SCM release tag, and the new development version.</li>
+ <li><code class="highlighter-rouge">mvn -Psigned_release release:perform -Darguments="-DskipTests"</code>, generate the artifacts and push them to the <a href="https://repository.apache.org/#stagingRepositories">Nexus repo</a>. If you would like to perform a dry run first (without pushing the artifacts to the repo), add the arg -DdryRun=true</li>
+</ol>
+
+<p>Now, the candidate release artifacts can be found in the <a href="https://repository.apache.org/#stagingRepositories">Nexus staging repo</a> and in the <code class="highlighter-rouge">target</code> folder of your local branch.</p>
+
+<p><strong>Tips:</strong> If you are performing a source-only release, please remove all artifacts from the staging repo besides the .zip file containing the source and the javadocs jar file. In the Nexus GUI, you can right click on each artifact to be deleted and then select <code class="highlighter-rouge">Delete</code>.</p>
+
+<h3 id="validate-the-release-candidate">Validate the Release Candidate</h3>
+<p>Now the release candidate is ready, before calling a vote, the artifacts must satisfy the following requirements:</p>
+
+<ul>
+ <li>Checksums and PGP signatures are valid.</li>
+ <li>Build is successful including unit and integration tests.</li>
+ <li>DISCLAIMER is correct and filenames must include “incubating”.</li>

+<h3 id="release-artifacts-to-dev-repository">Release Artifacts to Dev-Repository</h3>
+<p>If the release candidate passes the validation checklist, close the staging repository in Nexus by selecting the staging repository <code class="highlighter-rouge">orgapacherocketmq-XXX</code> and clicking on the <code class="highlighter-rouge">Close</code> icon.</p>
+
+<p>Nexus will now run through a series of checksum and signature validations.</p>
+
+<p>If the checks are passed, Nexus will close the repository and produce a URL to the closed staging repo (which contains the candidate artifacts). Include this URL in the voting email so that folks can find the staged candidate release artifacts.</p>
+
+<p>If the checks aren’t passed, fix the issues then go back and restart the release process.</p>
+
+<p>If everything is ok, use svn to copy the candidate release artifacts to RocketMQ repo: https://dist.apache.org/repos/dist/dev/incubator/rocketmq/${release version}.</p>
+
+<h2 id="vote-on-the-release">Vote on the Release</h2>
+
+<p>As per the Apache Incubator <a href="http://incubator.apache.org/incubation/Incubation_Policy.html#Releases">release guidelines</a>, all releases for incubating projects must go through a two-step voting process. First, release voting must successfully pass within the Apache RocketMQ community via the <strong>dev@rocketmq.incubator.apache.org</strong> mailing list. Then, release voting must successfully pass within the Apache Incubator PMC via the <strong>general@incubator.apache.org</strong> mailing list.</p>
+
+<p>General information regarding the Apache voting process can be found <a href="http://www.apache.org/foundation/voting.html">here</a>.</p>
+
+<h3 id="apache-rocketmq-community-vote">Apache RocketMQ Community Vote</h3>
+<p>To vote on a candidate release, send an email to the <a href="mailto:dev@rocketmq.apache.incubator.org">dev list</a> with subject <strong>[VOTE]: Release Apache RocketMQ <release version>(incubating) RC<RC Number></strong> and body:</p>
+
+<blockquote>
+ <p>Hello RocketMQ Community,</p>
+
+ <p>This is the vote for <release version> of Apache RocketMQ (incubating).</p>
+
+ <p><strong>The artifacts:</strong><br />

+
+ <p>The vote will be open for at least 72 hours or until necessary number of votes are reached.</p>
+
+ <p>Please vote accordingly:</p>

+[ ] +0 no opinion <br />
+[ ] -1 disapprove with the reason</p>
+
+ <p>Thanks,<br />
+The Apache RocketMQ Team</p>
+</blockquote>
+
+<p>Once 72 hours has passed (which is generally preferred) and/or at least three +1 (binding) votes have been cast with no -1 (binding) votes, send an email closing the vote and congratulate the release candidate. Please use the subject: <strong>[RESULT][VOTE]: Release Apache RocketMQ <release version>(incubating) RC<RC Number></strong> :</p>
+
+<blockquote>

+
+<p>If we do not pass the VOTE, fix the related issues, go back, restart the release process and increase RC number. When we call a new vote, we must use the updated mail subject: <strong>[RESTART][VOTE][#<Attempt Number>]: Release Apache RocketMQ <release version>(incubating) RC<RC Number></strong></p>

+
+ <p>— DISCLAIMER Apache RocketMQ is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code,it does indicate that the project has yet to be fully endorsed by the ASF.</p>

+<h1 id="overview">Overview</h1>
+
+<p>Apache RocketMQ is a distributed messaging and streaming platform with low latency, high performance and reliability, trillion-level capacity and flexible scalability. It consists of four parts: name servers, brokers, producers and consumers. Each of them can be horizontally extended without a single Point of Failure. As shown in screenshot above.</p>
+
+<p><strong>NameServer Cluster</strong></p>
+
+<p>Name Servers provide lightweight service discovery and routing. Each Name Server records full routing information, provides corresponding reading and writing service, and supports fast storage expansion.</p>
+
+<p><strong>Broker Cluster</strong></p>
+
+<p>Brokers take care of message storage by providing lightweight TOPIC and QUEUE mechanisms. They support the Push and Pull model, contains fault tolerance mechanism (2 copies or 3 copies), and provides strong padding of peaks and capacity of accumulating hundreds of billion messages in their original time order. In addition, Brokers provide disaster recovery, rich metrics statistics, and alert mechanisms, all of which are lacking in traditional messaging systems.</p>
+
+<p><strong>Producer Cluster</strong></p>
+
+<p>Producers support distributed deployment. Distributed Producers send messages to the Broker cluster through multiple load balancing modes. The sending processes support fast failure and have low latency.</p>
+
+<p><strong>Consumer Cluster</strong></p>
+
+<p>Consumers support distributed deployment in the Push and Pull model as well. It also supports cluster consumption and message broadcasting. It provides real-time message subscription mechanism and can meet most consumer requirements.
+RocketMQ’s website provides a simple quick-start guide to interested users.</p>
+
+<h1 id="nameserver">NameServer</h1>
+
+<p>NameServer is a fully functional server, which mainly includes two features:</p>
+
+<ul>
+ <li>Broker Management, <strong>NameServer</strong> accepts the register from Broker cluster and provides heartbeat mechanism to check whether a broker is alive.</li>
+ <li>Routing Management, each NameServer will hold whole routing info about the broker cluster and the <strong>queue</strong> info for clients query.</li>
+</ul>
+
+<p>As we know, RocketMQ clients(Producer/Consumer) will query the queue routing info from NameServer, but how do clients find NameServer address?</p>
+
+<p>There are four methods to feed NameServer address list to clients:</p>
+
+<ul>
+ <li>Programmatic Way, like <code class="highlighter-rouge">producer.setNamesrvAddr("ip:port")</code>.</li>
+ <li>Java Options, use <code class="highlighter-rouge">rocketmq.namesrv.addr</code>.</li>
+ <li>Environment Variable, use <code class="highlighter-rouge">NAMESRV_ADDR</code>.</li>
+ <li>HTTP Endpoint.</li>
+</ul>
+
+<p>More details about how to find NameServer address please refer to <a href="/rocketmq/four-methods-to-feed-name-server-address-list/">here</a>.</p>
+
+<h1 id="broker-server">Broker Server</h1>
+
+<p>Broker server is responsible for message store and delivery, message query, HA guarantee, and so on.</p>
+
+<p>As shown in image below, Broker server has searval important sub modules:</p>
+
+<ul>
+ <li>Remoting Module, the entry of broker, handles the requests from clients.</li>
+ <li>Client Manager, manages the clients (Producer/Consumer) and maintains topic subscription of consumer.</li>
+ <li>Store Service, provides simple APIs to store or query message in physical disk.</li>
+ <li>HA Service, provides data sync feature between master broker and slave broker.</li>
+ <li>Index Service, builds index for messages by specified key and provides quick message query.</li>
+</ul>

+<p>First of all, fork github’s <code class="highlighter-rouge">apache/incubator-rocketmq</code> to your own account on github and clone it as follows,</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git clone https://github.com/<your_github_name>/incubator-rocketmq.git
+</code></pre>
+</div>
+
+<p>Cloning this locally will set up <code class="highlighter-rouge">origin</code> to point to your remote fork on github as the default remote.
+Now you can create your pull requests.</p>
+
+<p>You will need to update a local master sometimes (to merge to your development branches).
+For this, you have to add remote for RocketMQ mirror as follows,</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git remote add upstream https://github.com/apache/incubator-rocketmq.git
+</code></pre>
+</div>
+
+<p>and update your local master via <code class="highlighter-rouge">git fetch</code> followed by <code class="highlighter-rouge">git rebase</code>, for instance:
+ git fetch upstream master
+ git rebase upstream/master</p>
+
+<h1 id="git-setup-for-committers">Git setup for Committers</h1>
+<p>In addition to contributors’ configurations, committers will have to attach the apache git repo:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git remote add apache https://git-wip-us.apache.org/repos/asf/incubator-rocketmq.git
+</code></pre>
+</div>
+
+<p>To check your remote setup, issue</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git remote -v
+</code></pre>
+</div>
+
+<p>You should see something like this:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>origin https://github.com/<your_github_name>/incubator-rocketmq.git (fetch)
+origin https://github.com/<your_github_name>/incubator-rocketmq.git (push)
+upstream https://github.com/apache/incubator-rocketmq.git (fetch)
+upstream https://github.com/apache/incubator-rocketmq.git (push)
+apache https://git-wip-us.apache.org/repos/asf/incubator-rocketmq.git (fetch)
+apache https://git-wip-us.apache.org/repos/asf/incubator-rocketmq.git (push)
+</code></pre>
+</div>
+
+<p>Now if you want to experiment with a branch everything, by default, points to your github account because ‘origin’ is default. You can work as normal using only github until you are ready to merge with the apache remote. Some conventions will integrate with Apache JIRA ticket numbers.</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git checkout -b ROCKETMQ-xxxx #xxxx typically is a JIRA ticket number
+</code></pre>
+</div>
+
+<p><em>To ensure the code quality of the master branch, all but minor changes should go through pull requests reviewed by peer committers.</em></p>
+
+<h1 id="do-some-work-on-the-branch">Do some work on the branch</h1>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git commit -a -m "doing some work"
+git push origin ROCKETMQ-xxxx # notice pushing to **origin** not **apache**
+</code></pre>
+</div>
+
+<p>Once you are ready to commit to the apache remote you can merge and push them directly, otherwise always create a PR.</p>
+
+<h1 id="how-to-create-a-pr-committers">How to create a PR (committers)</h1>
+
+<p>Push your branch to Github:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git checkout ROCKETMQ-xxxx
+git push origin ROCKETMQ-xxxx
+</code></pre>
+</div>
+
+<ol>
+ <li>
+ <p>Go to your ROCKETMQ-xxxx branch on Github. Since you forked it from Github’s apache/incubator-rocketmq. By default all PR will go to apache/master.</p>
+ </li>
+ <li>Click the green “Compare, review, and create pull request” button. You can edit the to and from for the PR if it isn’t correct. The “base fork” should be apache/incubator-rocketmq unless you are collaborating with one of the committers on the list. The “base” will be master. Don’t submit a PR to any other branches unless permitted by branch owner. The “head fork” will be your forked repo and the “compare” will be your ROCKETMQ-xxxx branch.</li>
+ <li>Click the “Create pull request” button and name the request “ROCKETMQ-xxxx” all caps. This will connect the comments of the PR to the mailing list and JIRA comments.</li>
+ <li>From now on the PR lives on github’s apache/incubator-rocketmq. You can use the commenting UI there.</li>
+ <li>If you are looking for a review or wanting to share with someone else please write a note in the comments and don’t worry about automated merging of your PR – you will have to do that later. The PR is tied to your branch so you can respond to comments, make fixes, and commit them from your local repo. They will appear on the PR page and be mirrored to JIRA and the mailing list.</li>
+ <li>When you are satisfied and want to push it to Apache’s remote repo, you can merge this PR.</li>
+</ol>
+
+<h1 id="how-to-create-a-pr-contributors">How to create a PR (contributors)</h1>
+<p>Before you create a pull request, make sure</p>
+<ol>
+ <li>A corresponding <a href="https://issues.apache.org/jira/browse/ROCKETMQ/">JIRA</a> issue is created and has a clear problem description.</li>
+ <li>Make sure you follow <a href="/docs/code-guidelines/">Coding Guidelines</a>.</li>
+ <li>You have unit tests for everything you are about to commit.</li>
+</ol>
+
+<p>For information about creating pull requests, please check <a href="https://help.github.com/articles/creating-a-pull-request/">GitHub PR docs</a>.</p>
+
+<p>Pull requests are made to <code class="highlighter-rouge">apache/incubator-rocketmq</code> repository on Github.
+In the Github UI you should pick the master branch as target of the PR. <br />
+You pull request will be reviewed and commented by committers, and issues can be discussed. When all reviewers are positive on the pull request, it will be merged.</p>
+
+<h1 id="merging-a-pr-yours-or-contributors">Merging a PR (yours or contributors)</h1>
+<p>Start with reading <a href="https://help.github.com/articles/checking-out-pull-requests-locally/">GitHub PR merging locally</a>. Remember that pull requests are equivalent to a remote github branch with potentially a multitude of commits. In this case it is recommended to squash remote commit history to have one commit per issue, rather than merging in a multitude of contributor’s commits. In order to do that, as well as to close the PR at the same time, it is recommended to use squash commits.
+Merging pull requests are equivalent to a “pull” of a contributor’s branch:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git checkout master # switch to local master branch
+git pull apache master # fast-forward to current remote HEAD
+git pull --squash https://github.com/cuser/incubator-rocketmq.git ROCKETMQ-xxxx # merge to master
+</code></pre>
+</div>
+
+<p><code class="highlighter-rouge">--squash</code> ensures all PR history is squashed into single commit, and allows committer to use his/her own message. Please refer to git help for merge or pull for more information about <code class="highlighter-rouge">--squash</code> option. In this example we assume that the contributor’s Github handle is “cuser” and the PR branch name is “ROCKETMQ-xxxx”. Next, resolve all conflicts, or ask a contributor to rebase on top of master, if PR went out of sync.</p>
+
+<p>If you are ready to merge your own (committer’s) PR you only need to merge (not pull), since you have a local copy that you’ve been working on. This is the branch that you used to create the PR.</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git checkout master # switch to local master branch
+git pull apache master # fast-forward to current remote HEAD
+git merge --squash ROCKETMQ-xxxx
+</code></pre>
+</div>
+
+<p>Please run regular patch checks, build with tests enabled, and change CHANGELOG whenever needed.
+If all requirements are met, you can commit the squashed request using:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git commit --author="contributor_name <contributor_email>" -a -m "ROCKETMQ-XXXX description closes apache/incubator-rocketmq#ZZ"
+</code></pre>
+</div>
+
+<p>ROCKETMQ-XXXX is all capitalized and ZZ is the pull request number on apache/incubator-rocketmq repository. Including “closes apache/incubator-rocketmq#ZZ” will close the PR automatically. More information can be found here <a href="https://help.github.com/articles/closing-issues-via-commit-messages/">GitHub PR closing docs.</a>.
+Next, push to git-wip-us.apache.org:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git push apache master
+</code></pre>
+</div>
+
+<p>(this will require Apache handle credentials).
+The PR, once pushed, will get mirrored to github. To update your github version push there too:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git push origin master
+</code></pre>
+</div>
+
+<p>Note on squashing: Since squash discards remote branch history, repeated PRs from the same remote branch are difficult to be merged. The workflow implies that every new PR starts with a new rebased branch. This is more important for contributors to know, rather than for committers, because if new PR is not mergeable, github would warn at the start. Please watch for dupe PRs (based on same source branches).</p>
+
+<h1 id="closing-a-pr-without-committing-for-committers">Closing a PR without committing (for committers)</h1>
+<p>When we want to reject a PR (close without committing), we can just issue an empty commit on master’s HEAD without merging the PR:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git commit --allow-empty -m "ROCKETMQ-XXXX closes apache/incubator-rocketmq#ZZ *Won't fix*"
+git push apache master
+</code></pre>
+</div>
+
+<p>that should close PR ZZ on github mirror without merging and any code modifications in the master repository.more detail please refer to RocketMQ PR https://github.com/apache/incubator-rocketmq/pull/15</p>
+
+<h1 id="apachegithub-integration-features">Apache/github integration features</h1>
+
+<p>Read <a href="https://blogs.apache.org/infra/entry/improved_integration_between_apache_and">infra blog</a>. Comments and PRs with RocketMQ issue handles should post to mailing lists and JIRA. RocketMQ issue handles must in the form ROCKETMQ-YYYYY (all capitals). Usually it makes sense to file a JIRA issue first, and then create a PR with description
+ROCKETMQ-YYYY: <jira-issue-description>
+All subsequent comments will then automatically be copied to JIRA.</jira-issue-description></p>
+
+<h1 id="best-practises">Best Practises</h1>
+
+<h2 id="avoiding-accidentally-committing-private-branches-to-the-asf-repo">Avoiding accidentally committing private branches to the ASF repo</h2>
+
+<p>It’s dangerous —especially when using IDEs— to accidentally commit changes to the ASF repo, be directed to the trunk, branch-2, other standard branch on which you are developing, or to a private branch you had intended to keep on github (or a private repo).</p>
+
+<p>Committers can avoid this by setting the directory in which they develop code to read only access to the ASF repository on github. A separate directory should also be set up with write access to the ASF repository as well as read access to your other repositories. Merging operations and push backs to the ASF repo are done from this directory —so it will be immune to all local changes.</p>
+
+<p>If you accidentally committed a patch to an ASF branch, do not attempt to roll back the branch and force out a new update. Simply commit and push out a new patch revoking the change.</p>
+
+<p>If you do accidentally committed a branch to the ASF repo, the infrastructure team can delete it —but they cannot stop it propagating to github and potentially being visible. Please avoid this.</p>

+<p>This page describes formatting rules and guidelines for software source code.</p>
+
+<p>Studies have shown that 80% of development time is spent on software maintenance which involves software source code understanding, refactoring and support. Established and enforced code formatting rules and guidelines improve source code readability, promote team code ownership, allow engineers understand new code more quickly and thorough as well as simplify maintenance.</p>

+
+<h1 id="producer">Producer</h1>
+
+<p>A producer sends messages generated by the business application systems to brokers. RocketMQ provides multiple paradigms of sending: synchronous, asynchronous and one-way.</p>
+
+<h2 id="producer-group">Producer Group</h2>
+
+<p>Producers of the same role are grouped together. A different producer instance of the same producer group may be contacted by a broker to commit or roll back a transaction in case the original producer crashed after the transaction.</p>
+
+<p><strong>Warning</strong>: Considering the provided producer is sufficiently powerful at sending messages, only one instance is allowed per producer group to avoid unnecessary initialization of producer instances.</p>
+
+<h1 id="consumer">Consumer</h1>
+
+<p>A Consumer pulls messages from brokers and feeds them into application. In perspective of user application, two types of consumers are provided:</p>
+
+<h2 id="pullconsumer">PullConsumer</h2>
+
+<p>Pull consumer actively pulls messages from brokers. Once batches of messages are pulled, user application initiates consuming process.</p>
+
+<h2 id="pushconsumer">PushConsumer</h2>
+
+<p>Push consumer, on the other hand, encapsulates message pulling, consuming progress and maintaining other work inside, leaving a callback interface to end user to implement which will be executed on message arrival.</p>
+
+<h2 id="consumer-group">Consumer Group</h2>
+
+<p>Similar to previously mentioned producer group, consumers of the exactly same role are grouped together and named <strong>Consumer Group</strong>.</p>
+
+<p>Consumer Group is a great concept with which achieving goals of load-balance and fault-tolerance, in terms of message consuming, is super easy.</p>
+
+<p><strong>Warning</strong>: consumer instances of a consumer group <strong>must</strong> have exactly the same topic subscription(s).</p>
+
+<h1 id="topic">Topic</h1>
+
+<p>Topic is a category in which producers deliver messages and consumers pull messages. Topics have very loose relationship with producers and consumers. Specifically, a topic may have zero, one or multiple producers that sends messages to it; conversely, a producer can send messages of different topics. In consumer’s perspective, a topic may be subscribed by zero, one or multiple consumer groups. And a consumer group, similarly, may subscribe to one or more topics as long as instances of this group keep their subscription consistent.</p>
+
+<h1 id="message">Message</h1>
+
+<p>Message is the information to be delivered. A message must have a topic, which can be interpreted as address of your letter to mail to. A message may also have an optional tag and extra key-value pairs. For example, you may set a business key to your message and look up the message on a broker server to diagnose issues during development.</p>
+
+<h2 id="message-queue">Message Queue</h2>
+
+<p>Topic is partitioned into one or more sub-topics, “message queues”.</p>
+
+<h2 id="tag">Tag</h2>
+
+<p>Tag, in other words sub-topic, provides extra flexibility to users. With tag, messages with different purposes from the same business module may have the same topic and different tag. Tags would be helpful to keep your code clean and coherent, and tags also can facilitate the query system RocketMQ provides.</p>
+
+<h2 id="broker">Broker</h2>
+
+<p>Broker is a major component of the RocketMQ system. It receives messages sent from producers, store them and prepare to handle pull requests from consumers. It also stores message related meta data, including consumer groups, consuming progress offsets and topic / queue info.</p>
+
+<h1 id="name-server">Name Server</h1>
+
+<p>Name server serves as the routing information provider. Producer/Consumer clients look up topics to find the corresponding broker list.</p>
+
+<h1 id="message-model">Message Model</h1>
+
+<ul>
+ <li>
+ <p>Clustering</p>
+ </li>
+ <li>
+ <p>Broadcasting</p>
+ </li>
+</ul>
+
+<h1 id="message-order">Message Order</h1>
+
+<p>When DefaultMQPushConsumer is employed, you may decide to consume messages orderly or concurrently.</p>
+
+<ul>
+ <li>Orderly</li>
+</ul>
+
+<p>Consuming messages orderly means messages are consumed the same order they are sent by producers for each message queue. If you are dealing with scenario that global order is mandatory, make sure the topic you use has only one message queue.</p>
+
+<p><strong>Warn</strong>: If consuming orderly is specified, the maximum concurrency of message consuming is the number of message queues subscribed by the consumer group.</p>
+
+<ul>
+ <li>Concurrently</li>
+</ul>
+
+<p>When consuming messages concurrently, maximum concurrency of message consuming is only limited by thread pool specified for each consumer client.</p>
+
+<p><strong>Warn</strong>: Message order is no longer guaranteed in this mode.</p>

+<h1 id="git-setup-for-contributors">Git setup for Contributors</h1>
+<p>First of all, fork github’s <code class="highlighter-rouge">apache/incubator-rocketmq</code> to your own account on github and clone it as follows,</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git clone https://github.com/<your_github_name>/incubator-rocketmq.git
+</code></pre>
+</div>
+
+<p>Cloning this locally will set up <code class="highlighter-rouge">origin</code> to point to your remote fork on github as the default remote.
+Now you can create your pull requests.</p>
+
+<p>You will need to update a local master sometimes (to merge to your development branches sometimes).
+For this, you have to add remote for RocketMQ mirror as follows,</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git remote add upstream https://github.com/apache/incubator-rocketmq.git
+</code></pre>
+</div>
+
+<p>and update your local master via <code class="highlighter-rouge">git fetch</code> followed by <code class="highlighter-rouge">git rebase</code>, for instance:
+ git fetch upstream master
+ git rebase upstream/master</p>
+
+<h1 id="git-setup-for-committers">Git setup for Committers</h1>
+<p>In addition to contributors’ configurations, committers will have to attach the apache git repo:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git remote add apache https://git-wip-us.apache.org/repos/asf/incubator-rocketmq.git
+</code></pre>
+</div>
+
+<p>To check your remote setup, issue</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git remote -v
+</code></pre>
+</div>
+
+<p>You should see something like this:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>origin https://github.com/<your_github_name>/incubator-rocketmq.git (fetch)
+origin https://github.com/<your_github_name>/incubator-rocketmq.git (push)
+upstream https://github.com/apache/incubator-rocketmq.git (fetch)
+upstream https://github.com/apache/incubator-rocketmq.git (push)
+apache https://git-wip-us.apache.org/repos/asf/incubator-rocketmq.git (fetch)
+apache https://git-wip-us.apache.org/repos/asf/incubator-rocketmq.git (push)
+</code></pre>
+</div>
+
+<p>Now if you want to experiment with a branch everything, by default, points to your github account because ‘origin’ is default. You can work as normal using only github until you are ready to merge with the apache remote. Some conventions will integrate with Apache JIRA ticket numbers.</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git checkout -b ROCKETMQ-xxxx #xxxx typically is a JIRA ticket number
+</code></pre>
+</div>
+
+<p><em>To ensure the code quality of the master branch, all but minor changes should go through pull requests reviewed by peer committers.</em></p>
+
+<h1 id="do-some-work-on-the-branch">Do some work on the branch</h1>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git commit -a -m "doing some work"
+git push origin ROCKETMQ-xxxx # notice pushing to **origin** not **apache**
+</code></pre>
+</div>
+
+<p>Once you are ready to commit to the apache remote you can merge and push them directly, otherwise always create a PR.</p>
+
+<h1 id="how-to-create-a-pr-committers">How to create a PR (committers)</h1>
+
+<p>Push your branch to Github:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git checkout ROCKETMQ-xxxx
+git push origin ROCKETMQ-xxxx
+</code></pre>
+</div>
+
+<ol>
+ <li>
+ <p>Go to your ROCKETMQ-xxxx branch on Github. Since you forked it from Github’s apache/incubator-rocketmq. By default all PR will go to apache/master.</p>
+ </li>
+ <li>Click the green “Compare, review, and create pull request” button. You can edit the to and from for the PR if it isn’t correct. The “base fork” should be apache/incubator-rocketmq unless you are collaborating with one of the committers on the list. The “base” will be master. Don’t submit a PR to any other branches unless permitted by branch owner. The “head fork” will be your forked repo and the “compare” will be your ROCKETMQ-xxxx branch.</li>
+ <li>Click the “Create pull request” button and name the request “ROCKETMQ-xxxx” all caps. This will connect the comments of the PR to the mailing list and JIRA comments.</li>
+ <li>From now on the PR lives on github’s apache/incubator-rocketmq. You can use the commenting UI there.</li>
+ <li>If you are looking for a review or wanting to share with someone else please write a note in the comments and don’t worry about automated merging of your PR – you will have to do that later. The PR is tied to your branch so you can respond to comments, make fixes, and commit them from your local repo. They will appear on the PR page and be mirrored to JIRA and the mailing list.</li>
+ <li>When you are satisfied and want to push it to Apache’s remote repo, you can merge this PR.</li>
+</ol>
+
+<h1 id="how-to-create-a-pr-contributors">How to create a PR (contributors)</h1>
+<p>Before you create a pull request, make sure</p>
+<ol>
+ <li>A corresponding <a href="https://issues.apache.org/jira/browse/ROCKETMQ/">JIRA</a> issue is created and has a clear problem description.</li>
+ <li>Make sure you follow <a href="/docs/code-guidelines/">Coding Guidelines</a>.</li>
+ <li>You have unit tests for everything you are about to commit.</li>
+</ol>
+
+<p>For information about creating pull requests, please check <a href="https://help.github.com/articles/creating-a-pull-request/">GitHub PR docs</a>.</p>
+
+<p>Pull requests are made to <code class="highlighter-rouge">apache/incubator-rocketmq</code> repository on Github.
+In the Github UI you should pick the master branch as target of the PR. <br />
+You pull request will be reviewed and commented by committers, and issues can be discussed. When all reviewers are positive on the pull request, it will be merged.</p>

+
+<p>Quality documentation is critically important to develop and maintain a project. The better the documentation is, the
+easier it will be for other participants to understand and respond properly.</p>
+
+<h2 id="api-documentation">API Documentation</h2>
+
+<p>The API is documented through javadoc comments.</p>
+
+<p>All classes, interfaces, methods and field variables should be documented. Public methods, in particular, should be
+commented fully – method purpose, return value, parameters and exceptions.</p>
+
+<p>Below is an example:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>/**
+ * Send message in synchronous mode. This method returns only when the sending procedure totally completes.
+ * </p>
+ *
+ * <strong>Warn:</strong> this method has internal retry-mechanism, that is, internal implementation will retry
+ * {@link #retryTimesWhenSendFailed} times before claiming failure. As a result, multiple messages may potentially
+ * delivered to broker(s). It's up to the application developers to resolve potential duplication issue.
+ *
+ * @param msg Message to send.
+ * @return {@link SendResult} instance to inform senders details of the deliverable, say Message ID of the message,
+ * {@link SendStatus} indicating broker storage/replication status, message queue sent to, etc.
+ * @throws MQClientException if there is any client error.
+ * @throws RemotingException if there is any network-tier error.
+ * @throws MQBrokerException if there is any error with broker.
+ * @throws InterruptedException if the sending thread is interrupted.
+ */
+@Override
+public SendResult send(Message msg) throws MQClientException, RemotingException, MQBrokerException, InterruptedException {
+ return this.defaultMQProducerImpl.send(msg);
+}
+</code></pre>
+</div>
+
+<h2 id="documentation-content">Documentation Content</h2>
+
+<p>Every class and interface should have summary documentation, explaining its general function and purpose. Additionally,
+thread safety information should be included. If you are working on a class which represents a core concept, adding sample
+usage is always a good practice.</p>
+
+<p>When writing API documentation, please keep a professional tune: write in active voice, be as descriptive as possible.
+Keep in mind that the audience may be a developer who would use RocketMQ for the first time, or a contributor who just gets
+ involved with the codebase. Either of them is not as familiar with Apache RocketMQ as you are.</p>

+<p>Use RocketMQ to send messages in three ways: reliable synchronous, reliable
+asynchronous, and one-way transmission.</p>
+
+<p>This page exemplifies these three message-sending ways. Checkout the notes along with the example to figure out which
+way to use for your specific use case.</p>
+
+<h4 id="reliable-synchronous-transmission">Reliable synchronous transmission</h4>
+
+<p>Application: Reliable synchronous transmission is used in extensive scenes, such as

+<p>This section introduces production-ready deployment solution. Generally speaking, we are deploying a resilient RocketMQ cluster having no single point of failure.</p>
+
+<h3 id="prerequisite">Prerequisite</h3>
+<p>Before starting this section, make sure you have read Quick Start section, and are farmiliar with the core concepts and components of RocketMQ.</p>
+
+<h4 id="production-ready-deployment">Production-ready Deployment</h4>
+<h5 id="name-server">Name Server</h5>
+<p>To ensure the cluster can still function when one instance crashes, two or more name server instances are recommended. As long as there is one name server instance alive, the whole cluster remains in service.</p>
+
+<p>Name server follows the share-nothing design paradigm. Brokers send heartbeat data to all name servers. Producers and consumers can query meta data from any of name servers available while sending / consuming messages.</p>
+
+<h4 id="broker">Broker</h4>
+<p>Brokers can be divided into two categories according to their roles: master and slave. Master brokers provide RW access while slave brokers only accept read access.</p>
+
+<p>To deploy a high-availability RocketMQ cluster with no single point of failure, a series of broker sets should be deployed. A broker set contains one master with brokerId set to 0 and several slaves with non-zero brokerIDs. All of the brokers in one set have the same brokerName. In serious scenarios, we should have at least two brokers in one broker set. Each topic resides in two or more brokers.</p>
+
+<h3 id="configuration">Configuration</h3>
+<p>When deploying a RocketMQ cluster, recommended configuration is listed below:</p>

+<h4 id="how-to-get">How To Get</h4>
+<p>The admin tool is shipped along with RocketMQ. Either you download a pre-built binary version or build from source by yourself, you already have it.</p>
+
+<p>In case you need the source code, the rocketmq-tools module contains its source code.</p>
+
+<h4 id="how-to-use">How to use</h4>
+<p>The Admin Tool is very easy to use. Here, for demonstration purpose, *nix environment is assumed.</p>

+<h3 id="replication-mode">Replication mode</h3>
+<p>To make sure that no successfully published message will be lost, RocketMQ provides a Replication mode to gain stronger durability and higher availability with two replication ways: Sync & Async.</p>
+
+<h5 id="replication-sync--async-broker">Replication: Sync / Async Broker</h5>
+
+<p>Like many replication system, sync brokers wait until commit log is replicated to the slave before acknowledging. Async brokers, instead, return immediately after messages are processed on master.</p>
+
+<h5 id="how-to-configure">How to configure</h5>
+<p>There are three pre-built configurations shipped with the distribution of RocketMQ under conf folder for your reference:</p>
+
+<div class="language-java highlighter-rouge"><pre class="highlight"><code><span class="mi">2</span><span class="n">m</span><span class="o">-</span><span class="mi">2</span><span class="n">s</span><span class="o">-</span><span class="n">sync</span>

+<span class="mi">2</span><span class="n">m</span><span class="o">-</span><span class="n">noslave</span>
+</code></pre>
+</div>
+<p>Note: all configurations uses ASYNC_FLUSH.</p>
+
+<h4 id="deployment">Deployment</h4>
+<p>Take the deployment of 2m-2s-sync as example. First, start up two name servers as is shown in the Quick Start section. Assume their IPs are 192.168.0.2 and 192.168.0.3.</p>
+
+<p>Then start the brokers(Assume binary RocketMQ is at /home/rocketmq/dist)</p>

+
+<h3 id="message-filtering">Message Filtering</h3>
+<p>So far, RocketMQ only supports message filtering feature by <code class="highlighter-rouge">TAG</code>, but one message can only own one tag, which is too limited to meet complex business requirements.</p>
+
+<p>So, we want to define and implement a reasonable filter language based on a subset of the SQL 92 expression syntax to support customized message filtering. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-121">JIRA</a></p>
+
+<h3 id="batch-messaging">Batch Messaging</h3>
+
+<p>In order to use RocketMQ in big data related scenarios, batch messaging is necessary and will bring million-level TPS for RocketMQ. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-80">JIRA</a>, <a href="https://github.com/apache/incubator-rocketmq/pull/53">PR</a></p>
+
+<h3 id="consistent-hash-allocate-strategychas">Consistent Hash Allocate Strategy(CHAS)</h3>
+
+<p>Consumer clients use the average allocate strategy by far, which is very sensitive when clients register or unregister continuously.</p>
+
+<p>A Consistent Hash allocate strategy is valuable for developers who care more about stabilization than averaging.</p>
+
+<p>So we decided to support CHAS as an extra choice in consumer load balancing. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-67">JIRA</a>, <a href="https://github.com/apache/incubator-rocketmq/pull/67">PR</a></p>
+
+<h3 id="global-order-messaging">Global Order Messaging</h3>
+
+<p>As we know, messages in the same queue can be consumed sequentially. So we always send the congeneric messages to the same queue to guarantee ordering, which will cause hot-point issue.</p>
+
+<p>So it’d be cool if we can support a new global order messaging mechanism without the hot-point problem. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-122">JIRA</a></p>
+
+<h3 id="distributed-transaction-messaging">Distributed Transaction Messaging</h3>
+<p>Undoubtedly, transaction messaging is frequently used in most business.</p>
+
+<p>But users have to implement transaction mechanism by themselves for now, so there is a potential need of a database implementation to solve the problem.</p>
+
+<p>Now we can support distributed transaction messaging to make it convenient for the users and help them handle complex business. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-123">JIRA</a></p>
+
+<h3 id="non-redundant-message-delivery-mechanism">Non-Redundant Message Delivery Mechanism</h3>
+
+<p>The duplicated messages will impose extra cost if user needs non-repeating messages.</p>
+
+<p>In most cases, user needs to store the consume records to determine if a message is duplicated, and the store stage should guarantee consistency. So we need to support a strict and non-redundant message delivery mechanism. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-124">JIRA</a></p>
+
+<h3 id="intellective-ha-architecture">Intellective HA Architecture</h3>
+
+<p>RocketMQ uses master-slave as HA architecture, which has low latency and high throughput, but this program needs human intervention to recover from abnormal situations.</p>
+
+<p>So, we want to support a multi-replication high availability／reliability mechanism, without human intervention. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-125">JIRA</a></p>
+
+<h3 id="docker-image">Docker Image</h3>
+<p>Provide a docker image for easy deployment and management, optimize for the latest version. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-126">JIRA</a></p>
+
+<h3 id="mqtt">MQTT</h3>
+<p>MQTT is a machine-to-machine (M2M)/”Internet of Things” connectivity protocol, which has been widely used in IoT. Support MQTT, give RocketMQ the power to connect everything. <a href="https://issues.apache.org/jira/browse/ROCKETMQ-127">JIRA</a></p>
+
+<h2 id="440-incubating-roadmap">4.4.0-incubating+ RoadMap:</h2>
+
+<ol>
+ <li>Support more application layer protocol: WebSocket, HTTP2, etc.</li>
+ <li>Support more native language SDK: PHP, Python, .Net, Node, Go, etc. The chosen programming languages are based on the investigation of many cloud platforms.</li>
+ <li>Support advanced message queuing protocol(AMQP).</li>
+</ol>
+
+<h2 id="rocketmq-externals">RocketMQ Externals</h2>
+
+<p>RocketMQ, as a message-oriented middleware, plays a connector role in distributed environment, so in order to embrace the ecological preferably, RocketMQ community needs a series of external projects to integrate with other excellent projects.</p>
