isInputConsumable

boolean isInputConsumable(SchedulingExecutionVertex executionVertex,
                          Set<ExecutionVertexID> verticesToSchedule,
                          Map<ConsumedPartitionGroup,Boolean> consumableStatusCache)

Determining whether the input of an execution vertex is consumable.

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.
