- 这是一个基于Sogou C++ Workflow的项目,兼具:
- 高性能
- 低开发和接入门槛
- 完美兼容workflow的串并联任务流
- 对于已有pb/thrift描述文件的项目,可以做到一键迁移
- 支持多种IDL格式,包括:
- Protobuf
- Thrift
- 支持多种数据布局,使用上完全透明,包括:
- Protobuffer serialize
- Thrift Binary serialize
- json serialize
- 支持多种压缩,使用上完全透明,包括:
- gzip
- zlib
- snappy
- lz4
- 支持多种通信协议,使用上完全透明,包括:
- tcp
- http
- sctp
- ssl
- https
- 用户可以通过http+json实现跨语言:
- 如果自己是server提供方,用任何语言的http server接受post请求,解析若干http header即可
- 如果自己是client调用方,用任何语言的http client发送post请求,添加若干http header即可
- 内置了可以与其他RPC框架的server/client无缝互通的client/server,包括:
- BPRC
GRPC- Thrift Framed Binary
- Thrift Http Binary
- 兼容workflow的使用方式:
- 提供创建任务的接口来创建一个rpc任务
- 可以把rpc任务放到任务流图中,回调函数里也可以拿到当前的任务流
- workflow所支持的其他功能,包括upstream、计算调度、异步文件IO等
- 更多功能和层次介绍
- srpc是一个静态库libsrpc.a,只有开发环境需要依赖libsrpc,编译后二进制发布不需要依赖libsrpc库
- srpc依赖workflow和protobuf3
- protobuf需要用户自行安装v3.0.0以上的版本
- workflow可以通过git的submodule形式进行依赖
- 压缩库snappy和lz4也以submodule的形式在third_party/中作源码依赖
