> 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.
