> Project: Flink
> Issue Type: Sub-task

> 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.
