storm trident实战 trident state

阅读更多

一、认识storm trident
    trident可以理解为storm批处理的高级抽象,提供了分组、分区、聚合、函数等操作,提供一致性和恰好一次处理的语义。
    1)元祖被作为batch处理
    2)每个batch的元祖都被指定唯一的一个事物id,如果因为处理失败导致batch重发,也和保证和重发前一样的事物id
    3)数据更新操作严格有序,比如batch1必须在batch2之前被成功处理,且如果batch1失败了,后面的处理也会失败。
    假如: batch1处理1--20
          batch2处理21--40
          batch1处理失败,那么batch2也会失败
    虽然数据更新操作严格有序,但是数据处理阶段也可以并行的,只是最后的持久化操作必须有序。
  1.1 trident state
     trident的状态具有仅仅处理一次,持续聚合的语义,使用trident来实现恰好一次的语义不需要开发人员去处理事务相关的工作,因为trident state已经帮我们封装好了,只需要编写类似于如下的代码:

  topology.newStream("sentencestream", spout)
                .each(new Fields("sentence"), new Split(), new Fields("word"))
                .groupBy(new Fields("word"))
                .persistentAggregate(new MyHbaseState.HbaseFactory(options), new Count(), new Fields("count"))
                .parallelismHint(3);

   所有处理事务逻辑都在MyHbaseState.HbaseFactory中处理了(这个是我自己定义的,trident支持在内存里面处理,类似于MemachedState.opaque)。
   trident提供了一个StateFactory用来创建State对象的实例,行如:

   public final class XFactory implements StateFactory{
       public State makeState(Map conf,int partitonIndex,int numPartitions){
            return new State();
       }
  }

  1.2 persistentAggregate
     persistentAggregate是trident中用来更新来源的状态,如果前面是一个分好组的流,trident希望你提供的状态实现MapState接口,其中key是分组的字段,
  而聚合结果是状态的值。
  1.3 实现MapStates
     trident中实现MapState非常简单,只需要为这个类提供一个IBackingMap的接口实现接口。
二、实战

    首先搭建好zk,storm,hadoop,hbase的分布式环境

    master:

  slave1:

  slave2:

    main方法:

     public static void main(String[] args) throws AlreadyAliveException, InvalidTopologyException, AuthorizationException {
        TridentTopology topology = new TridentTopology();
        FixedBatchSpout spout = new FixedBatchSpout(new Fields("sentence"), 3,
                new Values("tanjie is a good man"), new Values(
                        "what is your name"), new Values("how old are you"),
                new Values("my name is tanjie"), new Values("i am 18"));
        spout.setCycle(false);
        tridentStreamToHbase(topology,spout);
        Config config = new Config();
        config.setDebug(false);
        StormSubmitter.submitTopologyWithProgressBar("word_count_trident_state_HbaseState", config, topology.build());
    }

   tridentStreamToHbase方法:

  private static TridentState tridentStreamToHbase(TridentTopology topology,
            FixedBatchSpout spout) {
        MyHbaseState.Options options = new MyHbaseState.Options();
        options.setTableName("storm_trident_state");
        options.setColumFamily("colum1");
        options.setQualifier("q1");
        /**
         * 根据数据源拆分单词后,然后分区操作,在每个分区上又进行分组(hash算法),然后在每个分组上进行聚合
         * 所以这里可能有多个分区,每个分区有多个分组,然后在多个分组上进行聚合
         * 用来进行group的字段会以key的形式存在于State当中,聚合后的结果会以value的形式存储在State当中
         */
        return topology.newStream("sentencestream", spout)
                .each(new Fields("sentence"), new Split(), new Fields("word"))
                .groupBy(new Fields("word"))
                .persistentAggregate(new MyHbaseState.HbaseFactory(options), new Count(), new Fields("count"))
                .parallelismHint(3);
    }
