org.apache.flink.runtime.scheduler.strategy.PartialFinishedInputConsumableDecider

所有已实现的接口:

InputConsumableDecider

public class PartialFinishedInputConsumableDecider
extends Object
implements InputConsumableDecider

PartialFinishedInputConsumableDecider is a special InputConsumableDecider. The input is considered to be consumable:

• for hybrid input: when partial producer partitions are finished.
• for blocking input: when all producer partitions are finished.

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.

verticesToDeploy - 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.
