接口 WithPreCommitTopology<InputT,CommT>

所有超级接口:

Serializable, org.apache.flink.api.connector.sink2.Sink<InputT>, org.apache.flink.api.connector.sink2.TwoPhaseCommittingSink<InputT,CommT>

@Experimental
public interface WithPreCommitTopology<InputT,CommT>
extends org.apache.flink.api.connector.sink2.TwoPhaseCommittingSink<InputT,CommT>

Allows expert users to implement a custom topology after SinkWriter and before Committer.

It is recommended to use immutable committables because mutating committables can have unexpected side-effects.

addPreCommitTopology

DataStream<CommittableMessage<CommT>> addPreCommitTopology(DataStream<CommittableMessage<CommT>> committables)

Intercepts and modifies the committables sent on checkpoint or at end of input. Implementers need to ensure to modify all CommittableMessages appropriately.

参数:

committables - the stream of committables.

返回:

the custom topology before Committer.
