方法详细资料

vertexFinished

List<ConsumedPartitionGroup> vertexFinished(ExecutionVertexID finishedVertex)

Calling this method informs the strategy that a vertex finished.

参数:

finishedVertex - Id of the vertex that finished the execution

返回:

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.

参数:

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