What is it?

SRPC is an RPC framework written in C++ on top of Sogou's Workflow library. It serves multiple wire protocols (SRPC, bRPC, Thrift and tRPC) and accepts Protobuf or Thrift IDL definitions, with code generated for both client and server stubs.

Beyond basic calls, it supports JSON, Protobuf and Thrift binary data formats, gzip, zlib, snappy and lz4 compression, and tcp, udp, sctp and TLS transports. HTTP+JSON access lets clients in any language call a service over plain HTTP. Requests can be combined with Workflow's series and parallel primitives, and the framework includes AOP modules that report tracing to OpenTelemetry and metrics to OpenTelemetry or Prometheus.

Key features

  • 01Supports SRPC, bRPC, Thrift and tRPC protocols.
  • 02Accepts Protobuf and Thrift IDL with generated stubs.
  • 03Serves HTTP+JSON so any language can call services.
  • 04Compresses payloads with gzip, zlib, snappy or lz4.
  • 05Reports tracing to OpenTelemetry and metrics to Prometheus.

Use cases

  • Building high-throughput internal microservices in C++.
  • Letting bRPC or tRPC services interoperate with a Workflow-based codebase.
  • Exposing an RPC service over HTTP+JSON for clients in other languages.
  • Adding OpenTelemetry tracing and Prometheus metrics to C++ services.

Quick start

  1. 1

    Install srpc from source or the system package, following the installation guide

  2. 2

    Generate C++ code from example.proto

    protoc example.proto --cpp_out=./ --proto_path=./
  3. 3

    Compile the server (Linux)

    g++ -o server server.cc example.pb.cc -std=c++11 -lsrpc
  4. 4

    Start the server and run the client in another terminal

    ./server

Things to know

  • The quick start compile commands only cover Linux; other systems need the cmake setup from the tutorial.
  • The README gives no package-manager install command, so you must build from source or use a system package.
