public class ChangelogCompactCoordinateOperator
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<org.apache.flink.types.Either<Committable,ChangelogCompactTask>>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<Committable,org.apache.flink.types.Either<Committable,ChangelogCompactTask>>, org.apache.flink.streaming.api.operators.BoundedOneInput

Coordinator operator for compacting changelog files.

ChangelogCompactCoordinateOperator calculates the file size of changelog files contained in all buckets within each partition from Committable message emitted from writer operator. And emit ChangelogCompactTask to ChangelogCompactWorkerOperator.
