  17. def process(processCallback: Consumer[List[DeltaSourceSplit]]): Unit

    Process all AddFile from Snapshot passed to this SnapshotProcessor constructor by converting them to DeltaSourceSplit objects.

    Process all AddFile from Snapshot passed to this SnapshotProcessor constructor by converting them to DeltaSourceSplit objects.

    processCallback

    A Consumer callback that will be called after converting all AddFile to DeltaSourceSplit.

  19. def snapshotState(checkpointBuilder: DeltaEnumeratorStateCheckpointBuilder[DeltaSourceSplit]): DeltaEnumeratorStateCheckpointBuilder[DeltaSourceSplit]

    Add TableProcessor state information to DeltaEnumeratorStateCheckpointBuilder to be stored in Flink's checkpoint.

    Add TableProcessor state information to DeltaEnumeratorStateCheckpointBuilder to be stored in Flink's checkpoint.

    The implementation of this method should add the latest state information to DeltaEnumeratorStateCheckpointBuilder needed to recreate TableProcessor instance during Flink recovery.

    checkpointBuilder

    the DeltaEnumeratorStateCheckpointBuilder instance that should be updated with TableProcessor state information.

    returns

    the DeltaEnumeratorStateCheckpointBuilder instance with TableProcessor state information.
