Is it possible to combine asynchronous and synchronous services in one gRPC server?

Question

Or can I use a pair of server/client to handle synchronous requests and another pair to handle asynchronous request？ I'm just starting working on a distributed project which implements gRPC. I should have multiple database nodes and each should be able to send RPC to another. I have to allow both synchronous and asynchronous RPC here. One for general request and another one for 2 phase commit. But the gRPC tutorial does not mention if I should combine two services in one server and leave them separately. Thanks

Answer 1

It's not clear to me what exactly you want to achieve. If you want to have two gRPC services living in a single server, the answer is YES.

Define two sets of service definitions ServiceA.proto and ServiceB.proto and implement both in your server.
