A industrial-grade RPC framework used throughout Baidu, with 600,000+ instances(not counting clients) and 500+ kinds of services, called "baidu-rpc" inside Baidu. Only C++ implementation is opensourced right now.

You can use it to:

• Build a server that can talk in multiple protocols (on same port), or access all sorts of services
  • restful http/https, h2/h2c (compatible with grpc, will be opensourced). using http in brpc is much more friendly than libcurl.
  • redis and memcached, thread-safe, more friendly and performant than the official clients
  • rtmp/flv/hls, for building live-streaming services.
  • hadoop_rpc (may be opensourced)
  • rdma support (will be opensourced)
  • all sorts of protocols used in Baidu: baidu_std, streaming_rpc, hulu_pbrpc, sofa_pbrpc, nova_pbrpc, public_pbrpc, ubrpc, and nshead-based ones.
  • Access protobuf-based protocols with HTTP+json, probably from another language.
  • Build HA distributed services using an industrial-grade implementation of RAFT consensus algorithm (will be opensourced at braft)
• Create rich processing patterns
  • Services can handle requests synchronously or asynchronously.
  • Access service synchronously or asynchronously, or even semi-synchronously.
  • Use combo channels to simplify complicated client patterns declaratively, including sharded and parallel accesses.
• Debug services via http, and run cpu, heap and contention profilers.
• Get better latency and throughput.
• Extend brpc with the protocols used in your organization quickly, or customize components, including naming services (dns, zk, etcd), load balancers (rr, random, consistent hashing)

Contribute code

brpc welcomes contributions, especially those on adapting different platforms and extending protocols.

Make sure the code meets following requirements before submitting your PR:

• The code conforms to google C++ coding style and is indented by 4 spaces.
• The code appears where it should be. For example the code to support an extra protocol should not be put in general classes like server.cpp, channel.cpp, while a general modification would better not be hidden inside a very specific protocol.
• Has unittests.

Check following items after submitting the PR:

• Compilations and unittests in travis-ci are passed.
