@Internal
public class PartitionCommitter
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<Void>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<PartitionCommitInfo,Void>

Committer operator for partitions. This is the single (non-parallel) task. It collects all the partition information sent from upstream, and triggers the partition submission decision when it judges to collect the partitions from all tasks of a checkpoint.

NOTE: It processes records after the checkpoint completes successfully. Receive records from upstream CheckpointListener.notifyCheckpointComplete(long).

Processing steps: 1.Partitions are sent from upstream. Add partition to trigger. 2.TaskTracker say it have already received partition data from all tasks in a checkpoint. 3.Extracting committable partitions from PartitionCommitTrigger. 4.Using PartitionCommitPolicy chain to commit partitions.
