I have several Go and C++ services, that act as servers and clients, i.e. those are long-living services, that from time-to-time talk to other services.
I cannot find anywhere in gRPC docs whether the client channels and stubs should be long-lasting reusable objects or they should be created on every call. Or, maybe, I should create some kind of a channel/stub pool, where a pair of a channel and a stub exists, for example, for each thread and gets updated, refreshed on some interval or condition.
