Package org.apache.flink.state.api.output

Class 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.
