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.

getCoordinator

public ITridentSpout.BatchCoordinator getCoordinator(java.lang.String txStateId,
                                                     java.util.Map conf,
                                                     TopologyContext context)

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.
