      ICommitterTridentSpout.Emitter getEmitter(String txStateId, Map<String,Object> conf, TopologyContext context)
      Description copied from interface: ITridentSpout
      The emitter for a TransactionalSpout runs as many tasks across the cluster. Emitters are responsible for emitting batches of tuples for a transaction and must ensure that the same batch of tuples is always emitted for the same transaction id.

      All emitter tasks get the same transaction metadata. The topology context parameter contains the instance task id that can be used to distribute the work across the tasks.

      Specified by:
      getEmitter in interface ITridentSpout<X>
      txStateId - stream id
      conf - Storm config map
      context - topology context
