[bRPC](https://brpc.apache.org/) is an Industrial-grade RPC framework using C++ Language, which is often used in high performance system such as Search, Storage, Machine learning, Advertisement, Recommendation etc.
### "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](https://httpwg.org/specs/rfc9113.html)/[gRPC](https://grpc.io). using http/h2 in bRPC is much more friendly than [libcurl](https://curl.haxx.se/libcurl/). Access protobuf-based protocols with HTTP/h2+json, probably from another language.
* [redis](docs/en/redis_client.md) and [memcached](docs/en/memcache_client.md), thread-safe, more friendly and performant than the official clients.
* [rtmp](https://github.com/apache/brpc/blob/master/src/brpc/rtmp.h)/[flv](https://en.wikipedia.org/wiki/Flash_Video)/[hls](https://en.wikipedia.org/wiki/HTTP_Live_Streaming), for building [streaming services](https://github.com/brpc/media-server).
* hadoop_rpc (may be opensourced)
* [rdma](https://en.wikipedia.org/wiki/Remote_direct_memory_access) support
* [thrift](docs/en/thrift.md) support, thread-safe, more friendly and performant than the official clients.
* all sorts of protocols used in Baidu: [baidu_std](docs/en/baidu_std.md), [streaming_rpc](docs/en/streaming_rpc.md), hulu_pbrpc, [sofa_pbrpc](https://github.com/baidu/sofa-pbrpc), nova_pbrpc, public_pbrpc, ubrpc and nshead-based ones.
* Build [HA](https://en.wikipedia.org/wiki/High_availability) distributed services using an industrial-grade implementation of [RAFT consensus algorithm](https://raft.github.io) which is opensourced at [braft](https://github.com/brpc/braft)
* Servers can handle requests [synchronously](docs/en/server.md) or [asynchronously](docs/en/server.md#asynchronous-service).
* Clients can access servers [synchronously](docs/en/client.md#synchronus-call), [asynchronously](docs/en/client.md#asynchronous-call), [semi-synchronously](docs/en/client.md#semi-synchronous-call), or use [combo channels](docs/en/combo_channel.md) to simplify sharded or parallel accesses declaratively.
* Debug services [via http](docs/en/builtin_service.md), and run [cpu](docs/en/cpu_profiler.md), [heap](docs/en/heap_profiler.md) and [contention](docs/en/contention_profiler.md) profilers.
* Get [better latency and throughput](docs/en/overview.md#better-latency-and-throughput).
* [Extend bRPC](docs/en/new_protocol.md) with the protocols used in your organization quickly, or customize components, including [naming services](docs/en/load_balancing.md) (dns, zk, etcd), [load balancers](docs/en/load_balancing.md) (rr, random, consistent hashing)
