[~William Song] Not sure if IoTDb uses stateMachineCache. If so, yeah, I'm working on fixing a known problem from Zero-Copy, related to high off-heap memory occupation. RATIS-2093

> As GRPC has stabilized the API for zero-copy for protobuf ([https://github.com/grpc/grpc-java/issues/7387]), it's possible to have such memory efficiency feature in Ratis GRPC.
