> Currently, the serilization of ShuffleDescriptorGroup would happen in the RPC
> main thread even for light jobs. 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.
