org.apache.flink.runtime.scheduler.strategy.DefaultInputConsumableDecider

所有已实现的接口:

InputConsumableDecider

public class DefaultInputConsumableDecider
extends Object
implements InputConsumableDecider

Default implementation of InputConsumableDecider. This decider will judge whether the executionVertex's inputs are consumable as follows:

For blocking consumed partition group: Whether all result partitions in the group are finished.

For canBePipelined consumed partition group: whether all result partitions in the group are scheduled.

从接口复制的说明: InputConsumableDecider

Determining whether the input of an execution vertex is consumable.

指定者:

isInputConsumable 在接口中 InputConsumableDecider

参数:

executionVertex - to be determined whether it's input is consumable.

verticesToSchedule - vertices that are not yet scheduled but already decided to be scheduled.

consumableStatusCache - a cache for ConsumedPartitionGroup consumable status. This is to avoid repetitive computation.
