static interface	PartitionGroupReleaseStrategy.Factory	Factory for PartitionGroupReleaseStrategy.

Method Summary

Modifier and Type	Method	Description
List<ConsumedPartitionGroup>	vertexFinished(ExecutionVertexID finishedVertex)	Calling this method informs the strategy that a vertex finished.
void	vertexUnfinished(ExecutionVertexID executionVertexID)	Calling this method informs the strategy that a vertex is no longer in finished state, e.g., when a vertex is re-executed.

Method Details

vertexFinished

List<ConsumedPartitionGroup> vertexFinished(ExecutionVertexID finishedVertex)

Calling this method informs the strategy that a vertex finished.

Parameters:

finishedVertex - Id of the vertex that finished the execution

Returns:

A list of ConsumedPartitionGroups that can be released

vertexUnfinished

void vertexUnfinished(ExecutionVertexID executionVertexID)

Calling this method informs the strategy that a vertex is no longer in finished state, e.g., when a vertex is re-executed.

Parameters:

executionVertexID - Id of the vertex that is no longer in finished state.
