An industrial-grade RPC framework used throughout Baidu, with 1,000,000+ instances(not counting clients) and thousands kinds of services. "brpc" means "better RPC".

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/gRPC. using http/h2 in brpc is much more friendly than libcurl. Access protobuf-based protocols with HTTP/h2+json, probably from another language.
- redis and memcached, thread-safe, more friendly and performant than the official clients.
- rtmp/flv/hls, for building streaming services.
- hadoop_rpc (may be opensourced)
- rdma support (will be opensourced)
- thrift support, thread-safe, more friendly and performant than the official clients.
- all sorts of protocols used in Baidu: baidu_std, streaming_rpc, hulu_pbrpc, sofa_pbrpc, nova_pbrpc, public_pbrpc, ubrpc and nshead-based ones.
- Build HA distributed services using an industrial-grade implementation of RAFT consensus algorithm which is opensourced at braft
Servers can handle requests synchronously or asynchronously.
Clients can access servers synchronously, asynchronously, semi-synchronously, or use combo channels to simplify sharded or parallel accesses declaratively.
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)
