             Summary: Parallelized heavy serialization operations in StreamingJobGraphGenerator
                 Key: FLINK-26675
                 URL: https://issues.apache.org/jira/browse/FLINK-26675
             Project: Flink
          Issue Type: Sub-task
          Components: Client / Job Submission
            Reporter: Yangze Guo
            Assignee: Yangze Guo
             Fix For: 1.16.0


For some complex jobs, the compilation time of the job graph may exceed one second, which is unaffordable for short queries in the OLAP scenario. After a deeper investigation, we found that the hot path is the serialization of `OperatorCoordinator` and `StreamOperatorFactory`.

We proposed to parallelized these heavy serialization operations to accelerate the compilation of job graphs.
