Method Details

getConsumersParallelism

public int getConsumersParallelism(Function<JobVertexID,Integer> executionJobVertexParallelismRetriever,
 IntermediateDataSet intermediateDataSet)

Description copied from interface: ExecutionPlanSchedulingContext

Retrieves the parallelism of consumers connected to the specified intermediate data set.

Specified by:

getConsumersParallelism in interface ExecutionPlanSchedulingContext

Parameters:

executionJobVertexParallelismRetriever - A function that retrieves the parallelism of a job vertex.

intermediateDataSet - The intermediate data set whose consumer parallelism is queried.

Returns:

The parallelism of the consumers.

getConsumersMaxParallelism

public int getConsumersMaxParallelism(Function<JobVertexID,Integer> executionJobVertexMaxParallelismRetriever,
 IntermediateDataSet intermediateDataSet)

Description copied from interface: ExecutionPlanSchedulingContext

Retrieves the maximum parallelism of consumers connected to the specified intermediate data set.

Specified by:

getConsumersMaxParallelism in interface ExecutionPlanSchedulingContext

Parameters:

executionJobVertexMaxParallelismRetriever - A function that retrieves the maximum parallelism of a job vertex.

intermediateDataSet - The intermediate data set whose consumer maximum parallelism is queried.

Returns:

The maximum parallelism of the consumers.

getPendingOperatorCount

public int getPendingOperatorCount()

Description copied from interface: ExecutionPlanSchedulingContext

Retrieves the count of pending operators waiting to be transferred to job vertices.

Specified by:

getPendingOperatorCount in interface ExecutionPlanSchedulingContext

Returns:

the number of pending operators.

getStreamGraphJson

public String getStreamGraphJson()

Description copied from interface: ExecutionPlanSchedulingContext

Retrieves the JSON representation of the stream graph for the original job.

Specified by:

getStreamGraphJson in interface ExecutionPlanSchedulingContext

Returns:

the JSON representation of the stream graph, or null if the stream graph is not available.
