方法详细资料

applyJobResourceRequirements

public static Optional<VertexParallelismStore> applyJobResourceRequirements(VertexParallelismStore oldVertexParallelismStore,
                                                                            JobResourceRequirements jobResourceRequirements)

Create a new VertexParallelismStore that reflects given JobResourceRequirements.

参数:

oldVertexParallelismStore - old vertex parallelism store that serves as a base for the new one

jobResourceRequirements - to apply over the old vertex parallelism store

返回:

new vertex parallelism store iff it was updated

setParallelismInfo

public void setParallelismInfo(JobVertexID vertexId,
                               VertexParallelismInformation info)

从接口复制的说明: MutableVertexParallelismStore

Sets the parallelism properties for the given vertex.

指定者:

setParallelismInfo 在接口中 MutableVertexParallelismStore

参数:

vertexId - vertex to set parallelism for

info - parallelism information for the given vertex

getParallelismInfo

public VertexParallelismInformation getParallelismInfo(JobVertexID vertexId)

从接口复制的说明: VertexParallelismStore

Returns a given vertex's parallelism information.

指定者:

getParallelismInfo 在接口中 VertexParallelismStore

参数:

vertexId - vertex for which the parallelism information should be returned

返回:

a parallelism information for the given vertex
