[jira] [Created] (FLINK-26641) Optimize the time of fetching job status in the job submission of session cluster

----------------------------------

             Summary: Optimize the time of fetching job status in the job submission of session cluster
                 Key: FLINK-26641
                 URL: https://issues.apache.org/jira/browse/FLINK-26641
             Project: Flink
          Issue Type: Sub-task
          Components: Client / Job Submission, Runtime / REST
            Reporter: Yangze Guo
            Assignee: Yangze Guo
             Fix For: 1.16.0


Currently, in the session cluster, the client will wait until the job initialization is finished in the job submission period. However, it will first get the job details from the `ExecutionGraphCache`. For short queries in OLAP scenarios, the job might have been finished before the cache refreshed, which increase the e2e time of fetching the result.

We proposed to introduce a REST API for the job status to replace it.
