All Implemented Interfaces:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.BoundedOneInput, org.apache.flink.streaming.api.operators.Input<CompactMessages.CoordinatorInput>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, org.apache.flink.streaming.api.operators.OneInputStreamOperator<CompactMessages.CoordinatorInput,CompactMessages.CoordinatorOutput>, org.apache.flink.streaming.api.operators.StreamOperator<CompactMessages.CoordinatorOutput>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, org.apache.flink.streaming.api.operators.YieldingOperator<CompactMessages.CoordinatorOutput>

public class BatchCompactCoordinator
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<CompactMessages.CoordinatorOutput>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<CompactMessages.CoordinatorInput,CompactMessages.CoordinatorOutput>, org.apache.flink.streaming.api.operators.BoundedOneInput

Coordinator for compaction in batch mode. It will collect the written files in BatchFileWriter and determine whether to compact files or not as well as what files should be merged into a single file.

NOTE: The coordination is a stable algorithm, which can ensure different attempts will produce same outputs.
