java.lang.Object

org.apache.flink.runtime.operators.chaining.ChainedDriver<IN,OUT>

org.apache.flink.runtime.operators.chaining.SynchronousChainedCombineDriver<IN,OUT>

类型参数:

IN - The data type consumed by the combiner.

OUT - The data type produced by the combiner.

所有已实现的接口:

org.apache.flink.util.Collector<IN>

public class SynchronousChainedCombineDriver<IN,OUT>
extends ChainedDriver<IN,OUT>

The chained variant of the combine driver which is also implemented in GroupReduceCombineDriver. In contrast to the GroupReduceCombineDriver, this driver's purpose is only to combine the values received in the chain. It is used by the GroupReduce and the CombineGroup transformation.
