Class RestoreAndFailCommittableStateManager<GlobalCommitT>

java.lang.Object

org.apache.paimon.flink.sink.RestoreAndFailCommittableStateManager<GlobalCommitT>

All Implemented Interfaces:

Serializable, CommittableStateManager<GlobalCommitT>

public class RestoreAndFailCommittableStateManager<GlobalCommitT>
extends Object
implements CommittableStateManager<GlobalCommitT>

A CommittableStateManager which stores uncommitted ManifestCommittables in state.

When the job restarts, these ManifestCommittables will be restored and committed, then an intended failure will occur, hoping that after the job restarts, all writers can start writing based on the restored snapshot.

Useful for committing snapshots containing records. For example snapshots produced by table store writers.
