redis集群客户端JedisCluster优化 - 管道(pipeline)模式支持
来源：互联网 发布：js 给div添加右键事件 编辑：程序博客网 时间：2024/05/16 11:44
Redis在3.0版正式引入了集群这个特性，扩展变得非常简单。然而当你开心的升级到3.0后，却发现有些很好用的功能现在工作不了了， 比如我们今天要聊的pipeline功能。我们知道，普通的情况下，redis client与server之间采用的是请求应答的模式，即：
Client: command1
Server: response1
Client: command2
Server: response2
…
在这种情况下，如果要完成10个命令，则需要20次交互才能完成。因此，即使redis处理能力很强，仍然会受到网络传输影响，导致吞吐上不去。而在管道模式下，多个请求变成这样：
Client: command1，command2…
Server: response1，response2…
在这种情况下，完成命令只需要2次交互。这样网络传输上能够更加高效，加上redis本身强劲的处理能力，是不是有一种飞一样的感觉。听到这里有没有去优化应用的冲动？ 然而到了cluster模式下，这样的功能并不支持。 下面我们先来分析下，是什么原因导致redis cluter没办法支持管道模式。首先需要了解集群下的几个特性：
- 1、集群将空间分拆为16384个槽位(slot)，每一个节点负责其中一些槽位。迁移时对整个slot迁移
- 2、节点添加，或宕机或不可达的情况下可以正常使用
- 3、不存在中心或者代理节点， 每个节点中都包含集群所有的节点信息
- 4、集群中的节点不会代理请求：即如果client将命令发送到错误的节点上，操作会失败，但会返回”-MOVED”或”-ASK”，供client进行永久或临时的节点切换
以上信息中第3、4点信息比较重要。
我们先来看第3点，由于每个节点都包含所有的节点信息，因此client连接任一节点都可以获取整个集群的信息，这样我们在配置JedisCluster时只需要配置其中一部分节点的信息就可以（配置多个是为了高可用）。对应的获取集群命令为：cluster nodes
127.0.0.1:9380> cluster nodes
b6d0cfe64dbae9590e6fc4c5a8e309debcbe0529 127.0.0.1:9380 myself,master - 0 0 2 connected 5461-10922
b9e5592558aae0f28c79c3750b264d5b2530f6a4 127.0.0.1:9381 master - 0 1466758609932 3 connected 10923-16383
b40095eb2023653eaea5b7b4e242a77a7817889a 127.0.0.1:9379 master - 0 1466758608932 1 connected 0-5460
每一行代表一个节点的信息，这里共三个节点（测试用，没有建slave节点），依次的信息为：
{id} {ip:port} {flags如master/slave} {master id} {ping-sent} {pong-recv} {config-epoch} {link-state} {slot} {slot} … {slot}
参考： http://redis.io/commands/cluster-nodes
可以看到每个节点对应的slot信息都在这里，{slot}格式一般是{begin}-{end}（如0-5460）,表示从{begin}到{end}的所有slot都在当前节点中。因此我们可以通过slot找到对应机器的ip:port。 注意，新版client中使用cluster slots获取对应数据 ， 参考： http://redis.io/commands/cluster-slots 。
再来看第4点，由第3点可以知道client可以通过获取所有节点信息，根据key计算得到对应的slot后可以找到对应的节点。所以说在节点稳定（没有增减）的情况下，客户端可以一直用缓存的集群信息来发起各种命令。然而，如果节点发生变更客户端是否能够立即感知？ 目前的client JedisCluster是无法感知的，他是通过执行命令后, 服务端返回的“-MOVED”信息感知节点的变化，并以此来刷新缓存信息。
了解以上信息以后，JedisCluster为什么不支持pipeline就比较清晰了。 因为pipeline模式下命令将被缓存到对应的连接(OutputStream)上，而在真正向服务端发送数据时，节点可能发生了改变，数据就可能发向了错误的节点，这导致批量操作失败，而要处理这种失败是非常复杂的。至少目前JedisCluster并未提供这样的机制。（对于单key来说，在发生这种情况的时候，进行简单的节点数据刷新+重新发送当前命令来重试）。
看到这里，你可能会感到沮丧（我猿类如此不易，且行且珍惜）。这里提供一个简单的思路，你可以根据单key的逻辑，如果某些key遇到”-MOVE”或”-ASK”则重试。 根据这个思路，你需要按顺序记录所有的命令，每次执行完成后找出异常的数据，刷新节点信息后重试，最终将重试（可能有多次）获取到的结果根据顺序信息插入返回列表。对于重试多次依然失败的数据，交由业务处理。思路很简单，然而redis命令太多了，要对PipelineBase的每个方法都这样改造，我不想（因为我懒呀），而且估计坑也很多，所以这个只能靠你自己去搞了。
下面我说下针对我们的业务做的一个JedisCluster pipeline实现。对应的业务有以下特点：
- 数据为每隔一段时间全量导入redis集群，数据量约xx万（xx较大）
- 导入任务为后台执行，可重试，最终如果有部分失败可接受
- 集群相对较稳定，不会频繁的加减机器
- 在线业务不使用该api
下面是该类的源码（jdk1.7)，如在以上这几个条件下有问题，可以一起交流：

在集群模式下提供批量操作的功能。 <br/> * 由于集群模式存在节点的动态添加删除，且client不能实时感知（只有在执行命令时才可能知道集群发生变更）， * 因此，该实现不保证一定成功，建议在批量操作之前调用 refreshCluster() 方法重新获取集群信息。<br /> * 应用需要保证不论成功还是失败都会调用close() 方法，否则可能会造成泄露。<br/> * 如果失败需要应用自己去重试，因此每个批次执行的命令数量需要控制。防止失败后重试的数量过多。<br /> * 基于以上说明，建议在集群环境较稳定（增减节点不会过于频繁）的情况下使用，且允许失败或有对应的重试策略。<br /> * * *<span class="hljs-javadoctag" style="color:#66066;box-sizing: border-box;">
