Kitex [kaɪt'eks] is a high-performance and strong-extensibility Go 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 a significant performance advantage over go net.

• Extensibility

Kitex provides many interfaces with default implementations 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.

High-performance IPC solution based on shared memory IPC.

基于共享内存 IPC 的高性能进程间通信解决方案。

Introduction

Shmipc is a high performance inter-process communication library developed by ByteDance. It is built on Linux's shared memory technology and uses unix or tcp connection to do process synchronization and finally implements zero copy communication across inter-processes. In IO-intensive or large-package scenarios, it has better performance.

Features

Zero copy

In an industrial production environment, the unix domain socket and tcp loopback are often used in inter-process communication.The read operation or the write operation need copy data between user space buffer and kernel space buffer.But shmipc directly store data to the share memory, so no copy compared to the former.

batch IO

An IO queue was mapped to share memory, which describe the metadata of communication data. so that a process could put many request to the IO queue, and other process could handle a batch IO per synchronization. It could effectively reduce the system calls which was brought by process synchronization.

简介

Shmipc是字节跳动开发的一款高性能进程间通信库。该库基于Linux共享内存技术构建，通过Unix或TCP连接实现进程同步，最终达成跨进程零拷贝通信。在IO密集型或大数据包传输场景下，其性能表现尤为突出。

特性

零拷贝

在工业生产环境中，Unix域套接字和TCP回环接口常被用于进程间通信。读写操作需要在用户空间缓冲区与内核空间缓冲区之间进行数据拷贝。而shmipc直接将数据存储于共享内存，相较前者实现了零拷贝。

批量IO

将IO队列映射至共享内存，该队列用于描述通信数据的元信息。因此一个进程可批量提交多个请求，另一进程则能在每次同步时处理批量IO操作。这种设计能有效减少进程同步带来的系统调用开销。
