How about Akka-grpc with flatbuffers, thoughts/possibility?

Though AkkaGRPC works seamlessly with ProtoBuffers, GRPC has stated out of box support for FlatBuffers any chance it will be possible to use FlatBuffers instead of ProtoBuffers in AkkaGrpc?

p.s I understand ProtoBuffers give quite a good performance but as stated FlatBuffers are still slightly better, food for thought?

It’s not currently possible as far as I can see, Akka gRPC is quite tightly coupled with Protobuf to make that really convenient (since that is the de-facto way gRPC is used).

Making it possible to switch between Protobuf and other formats would probably require quite an effort, work wise.

What about that topic in this days? akka grpc becomes better and better, whats about flatbuffers?
