Kitex [kaɪt'eks] is a high-performance and strong-extensibility Golang RPC framework that helps developers build microservices. If the performance and extensibility are the main concerns when you develop microservices, Kitex can be a good choice.

Basic Features

  • High Performance

Kitex integrates Netpoll, a high-performance network library, which offers significant performance advantage over go net.

  • Extensibility

Kitex provides many interfaces with default implementation for users to customize. You can extend or inject them into Kitex to fulfill your needs (please refer to the framework extension section below).

  • Multi-message Protocol

Kitex is designed to be extensible to support multiple RPC messaging protocols. The initial release contains support for Thrift, Kitex Protobuf and gRPC, in which Kitex Protobuf is a Kitex custom Protobuf messaging protocol with a protocol format similar to Thrift. Kitex also supports developers extending their own messaging protocols.

  • Multi-transport Protocol

For service governance, Kitex supports TTHeader and HTTP2. TTHeader can be used in conjunction with Thrift and Kitex Protobuf.

  • Multi-message Type

Kitex supports PingPong, One-way, and Bidirectional Streaming. Among them, One-way currently only supports Thrift protocol.

  • Service Governance

Kitex integrates service governance modules such as service registry, service discovery, load balancing, circuit breaker, rate limiting, retry, monitoring, tracing, logging, diagnosis, etc. Most of these have been provided with default extensions, giving users the option to integrate them as desired.

  • Code Generation

Kitex has built-in code generation tools that support generating Thrift, Protobuf, and scaffold code.

Performance

Performance benchmark can only provide limited reference. In production, there are many factors can affect actual performance.

We provide the kitex-benchmark project to track and compare the performance of Kitex and other frameworks under different conditions for reference.

  • Netpoll: A high-performance network library.
  • kitex-contrib: A partial extension library of Kitex, which users can integrate into Kitex through options according to their needs.
  • kitex-examples: Examples of Kitex showcasing various features.
  • biz-demo: Business demos using Kitex.
