decideParallelismAndInputInfosForVertex

ParallelismAndInputInfos decideParallelismAndInputInfosForVertex(JobVertexID jobVertexId,
                                                                 List<BlockingResultInfo> consumedResults,
                                                                 int vertexInitialParallelism,
                                                                 int vertexMaxParallelism)

Decide the parallelism and JobVertexInputInfos for this job vertex.

参数:

jobVertexId - The job vertex id

consumedResults - The information of consumed blocking results

vertexInitialParallelism - The initial parallelism of the job vertex. If it's a positive number, it will be respected. If it's not set(equals to ExecutionConfig.PARALLELISM_DEFAULT), a parallelism will be automatically decided for the vertex.

vertexMaxParallelism - The max parallelism of the job vertex.

返回:

the parallelism and vertex input infos.
