Where is the Thrift format specification?

Thrift is a software framework for scalable cross-language service development. It integrates a software stack with a code generation engine to facilitate the development of services that efficiently transmit data across programming languages such as C++, Java, and Python.

For the Thrift format specification, you can find relevant documentation and guides on the official Apache Thrift website. The Thrift format specification is primarily defined in its IDL (Interface Definition Language), which is used to define data types and service interfaces for Thrift services.

Specifically, you can access the latest specification documentation for the Thrift IDL by visiting the Apache Thrift GitHub repository or its official website. These documents provide detailed descriptions of how to define data structures, services, and exceptions, among others.

For example, if you need to define a simple user information service, you can write it in the Thrift IDL as follows:

thrift
struct User {
  1: string name,
  2: i32 age,
  3: string email
}

service UserService {
  User getUser(1: string email),
  void createUser(1: User user)
}

In this example, User is a struct that contains the user's name, age, and email. UserService is a service that includes methods for retrieving user information and creating new users.

In this way, Thrift enables seamless communication and data exchange between applications written in different languages. We hope this example helps you better understand the Thrift format specification and its practical applications.
