Method Detail

isInputConsumable

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

Description copied from interface: InputConsumableDecider

Determining whether the input of an execution vertex is consumable.

Specified by:

isInputConsumable in interface InputConsumableDecider

Parameters:

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.

isConsumableBasedOnFinishedProducers

public boolean isConsumableBasedOnFinishedProducers(ConsumedPartitionGroup consumedPartitionGroup)

Description copied from interface: InputConsumableDecider

Determining whether the consumed partition group is consumable based on finished producers.

Specified by:

isConsumableBasedOnFinishedProducers in interface InputConsumableDecider

Parameters:

consumedPartitionGroup - to be determined whether it is consumable.
