Class BootstrapStreamTaskRunner<IN>

java.lang.Object
org.apache.flink.streaming.api.operators.AbstractStreamOperator<TaggedOperatorSubtaskState>
org.apache.flink.state.api.output.BootstrapStreamTaskRunner<IN>
Type Parameters:
IN - Type of the input to the partition
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<IN>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,TaggedOperatorSubtaskState>, org.apache.flink.streaming.api.operators.StreamOperator<TaggedOperatorSubtaskState>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, org.apache.flink.streaming.api.operators.YieldingOperator<TaggedOperatorSubtaskState>
@Internal public class BootstrapStreamTaskRunner<IN> extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<TaggedOperatorSubtaskState> implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,TaggedOperatorSubtaskState>, org.apache.flink.streaming.api.operators.BoundedOneInput
The runtime for a BootstrapStreamTask.

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.
