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.
- High Performance
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; HTTP2 is currently mainly used with the gRPC protocol, and it will support Thrift in the future.
- Multi-message Type
Kitex supports PingPong, One-way, and Bidirectional Streaming. Among them, One-way currently only supports Thrift protocol, two-way Streaming only supports gRPC, and Kitex will support Thrift’s two-way Streaming in the future.
- 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, and users can choose to integrate.
- Code Generation
Kitex has built-in code generation tools that support generating Thrift, Protobuf, and scaffold code.
Note: The performance benchmarks obtained from the experiment are for reference only, because there are many factors that can affect the actual performance in application scenarios.
