If your communication is limited to simple collaborative signal passing or sharing some data between two processes you can safely use NamedPipeClientStream and NamedPipeServerStream on local system or local network but if you plan for the same on different systems then I would suggest using TcpClient and TcpListener. my proto: rpc call (google. Client-server coupling. I will address the issue of performance later but from that point of view alone your statement "the latency of zmq is better" is plainly wrong. the engines’ perspective: every time a new engine gets “elected” as leader, it starts a gRPC server. com Sep 15, 2020 · Popular frameworks like gRPC, Thrift or GraphQL do have bindings for almost every commonly used language.

Multi-language performance tests run every few hours against the master branch, and these numbers are reported to a dashboard for visualization. The TCP-socket approach will work in multi-host container setups (Kubernetes, Docker Swarm, Amazon ECS) but you intrinsically cannot share a Unix socket in these environments. It creates a lot of context switching because you create a message via dbus, send it to the kernel, then send it back out to dbus. The code generated by Qt GRPC enables the client-side Aug 11, 2017 · In any case gRPC largely follows HTTP semantics (over HTTP/2) but explicitly allow for full-duplex streaming, diverging from typical REST conventions as it uses static paths for performance reasons during call dispatch as parsing call parameters from paths ― query parameters and payload body adds latency and complexity.
