> Currently, the serilization of ShuffleDescriptorGroup would happen in the RPC
> main thread even for light jobs. That would harm the QPS of OLAP session,
> e.g. the deserialization will take 3ms at TM side for each task of a 128*128
> wordcount job. We propose to move it out of the rpc main thread. For heavy
> jobs, it still worth to cache the serialized value for memory efficiency. At
> the same time we need to make the serialization thread pool configurable.
