Method Detail

vertexFinished

public List<IntermediateResultPartitionID> vertexFinished(ExecutionVertexID finishedVertex)

Description copied from interface: PartitionReleaseStrategy

Calling this method informs the strategy that a vertex finished.

Specified by:

vertexFinished in interface PartitionReleaseStrategy

Parameters:

finishedVertex - Id of the vertex that finished the execution

Returns:

A list of result partitions that can be released

vertexUnfinished

public void vertexUnfinished(ExecutionVertexID executionVertexId)

Description copied from interface: PartitionReleaseStrategy

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

Specified by:

vertexUnfinished in interface PartitionReleaseStrategy

Parameters:

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