Interface IPartitionedTridentSpout<Partitions,Partition extends ISpoutPartition,T>

All Superinterfaces:

Serializable

public interface IPartitionedTridentSpout<Partitions,Partition extends ISpoutPartition,T>
extends Serializable

This interface defines a transactional spout that reads its tuples from a partitioned set of brokers. It automates the storing of metadata for each partition to ensure that the same batch is always emitted for the same transaction id. The partition metadata is stored in Zookeeper.
