Class BoundedOneInputStreamTaskRunner<IN>

java.lang.Object

org.apache.flink.api.common.functions.AbstractRichFunction

org.apache.flink.api.common.functions.RichMapPartitionFunction<IN,TaggedOperatorSubtaskState>

org.apache.flink.state.api.output.BoundedOneInputStreamTaskRunner<IN>

Type Parameters:

IN - Type of the input to the partition

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.MapPartitionFunction<IN,TaggedOperatorSubtaskState>, org.apache.flink.api.common.functions.RichFunction

@Internal
public class BoundedOneInputStreamTaskRunner<IN>
extends org.apache.flink.api.common.functions.RichMapPartitionFunction<IN,TaggedOperatorSubtaskState>

A RichMapPartitionFunction that serves as the runtime for a BoundedStreamTask.

The task is executed processing the data in a particular partition instead of the pulling from the network stack. After all data has been processed the runner will output the OperatorSubtaskState from the snapshot of the bounded task.
