Class DataFileRewriteCommitter

java.lang.Object

org.apache.flink.streaming.api.operators.AbstractStreamOperator<Trigger>

org.apache.iceberg.flink.maintenance.operator.DataFileRewriteCommitter

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.Input<DataFileRewriteRunner.ExecutedGroup>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, org.apache.flink.streaming.api.operators.OneInputStreamOperator<DataFileRewriteRunner.ExecutedGroup,Trigger>, org.apache.flink.streaming.api.operators.StreamOperator<Trigger>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, org.apache.flink.streaming.api.operators.YieldingOperator<Trigger>

@Internal
public class DataFileRewriteCommitter
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<Trigger>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<DataFileRewriteRunner.ExecutedGroup,Trigger>

Commits the rewrite changes using RewriteDataFilesCommitManager. The input is a DataFileRewriteRunner.ExecutedGroup. Only Watermark is emitted which is chained to TaskResultAggregator input 1.
