Description copied from interface: ITridentSpout

The coordinator for a TransactionalSpout runs in a single thread and indicates when batches of tuples should be emitted and when transactions should commit. The Coordinator that you provide in a TransactionalSpout provides metadata for each transaction so that the transactions can be replayed.

getEmitter

public ICommitterTridentSpout.Emitter getEmitter(String txStateId,
                                                 Map 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.
