SnapshotAndChangesTableProcessor

class SnapshotAndChangesTableProcessor extends ContinuousTableProcessor

This implementation of TableProcessor process both, content of io.delta.standalone.Snapshot and changes applied to monitored Delta table by converting them to DeltaSourceSplit objects.

This implementation uses both SnapshotProcessor to read Snapshot content and ChangesProcessor to read all changes applied after snapshot processed by encapsulated SnapshotProcessor.

  10. def getSnapshotVersion(): Long

    returns

    Snapshot version that this processor currently process. The value returned by this method can be different for every call, since this processor also process changes applied to monitored Delta table.

    Starts processing content of io.delta.standalone.Snapshot defined by #snapshotProcessor and Delta table changes applied after that snapshot.

    Starts processing content of io.delta.standalone.Snapshot defined by #snapshotProcessor and Delta table changes applied after that snapshot.

    processCallback

    A Consumer callback that will be called after processing Snapshot content by #snapshotProcessor and all io.delta.standalone.actions.Action after converting them to DeltaSourceSplit. This callback will be executed for every new discovered Delta table version.

    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.
