Package org.apache.storm.trident.spout

Interface IOpaquePartitionedTridentSpout<PartitionsT,PartitionT extends ISpoutPartition,M>

Type Parameters:

M - The type of metadata object passed to the Emitter when emitting a new batch based on a previous batch. This type must be JSON serializable by json-simple.

PartitionsT - The type of metadata object used by the coordinator to describe partitions. This type must be JSON serializable by json-simple.

All Superinterfaces:

ITridentDataSource, Serializable

All Known Implementing Classes:

KafkaTridentSpoutOpaque

public interface IOpaquePartitionedTridentSpout<PartitionsT,PartitionT extends ISpoutPartition,M>
extends ITridentDataSource

This defines a transactional spout which does *not* necessarily replay the same batch every time it emits a batch for a transaction id.
