SOFABolt Project

1. Introduction

SOFABolt is a network communication framework based on Netty developed by Ant Financial Services Group.

• In order to allow Java programmers to focus more on the implementation of business logic based on network communication, instead of being too entangled in the implementation of NIO at the bottom of the network and dealing with network problems that are difficult to debug, Netty came into being.
• In order to allow middleware developers to focus more on the implementation of product features instead of repeatedly manufacturing the wheels of communication frameworks over and over again, SOFABolt came into being.

Bolt is named after the Disney animation - Bolt. It is a lightweight, easy-to-use, high-performance, and easy-to-extend communication framework based on Netty best practices. Over the years, we have solved many problems in network communication with microservices and message middleware, accumulated a lot of experience, and continue to optimize and improve. We hope to integrate the summarized solutions into the basic component SOFABolt. Allowing more scenarios using network communication to benefit uniformly. At present, this product has been used in many products such as Ant middleware's microservices (SOFARPC), message center, distributed transactions, distributed switches, and configuration centers.

2. Function introduction

SOFABolt’s basic functions include:

• Basic communication functions (remoting-core)
  • Efficient network IO and thread model application based on Netty
  • Connection management (lock-free connection establishment, scheduled link disconnection, automatic reconnection)
  • Basic communication model (oneway, sync, future, callback)
  • Timeout control
  • Batch unpacking and batch submission processor
  • Heartbeat and IDLE event handling
• Protocol skeleton (protocol-skeleton)
  • Commands and command processors
  • Codec processor
  • heartbeat trigger
• Customized implementation of private protocol - RPC communication protocol (protocol-implementation)
  • Design of RPC communication protocol
  • Flexible deserialization timing control
  • Request processing timeout FailFast mechanism
  • User request processor (UserProcessor)
  • duplex communication

Usage 1

Using SOFABolt as a remote communication framework, users can directly use our built-in RPC communication protocol without worrying about the details of how to implement a private protocol. It is very simple to start the client and server, and register a user request handler at the same time to complete the remote call. At the same time, basic features such as connection management and heartbeat are available by default. The currently supported call types are shown in the figure below:

• For sample Demo, please refer to our user manual

Usage 2

Using SOFABolt as a protocol framework, users can reuse basic functions such as the basic communication model and the interface definitions included in the protocol. Then customize the Command type, Command processor, codec processor, etc. according to the private protocol you designed. As shown in the figure below, the Command definition structure of RPC and messages:
