Contributing to TiDB's codebase is not easy, especially for newbies. As a distributed database, TiDB has multiple components and numerous tools, written in multiple languages, including Go and Rust. Getting started with such a complicated system takes quite an effort.
So, in order to welcome newcomers to TiDB and make it easier for them to contribute to our community, we've developed a TiDB integrated development environment: TiDE. Created during TiDB Hackathon 2020, TiDE is a Visual Studio Code extension that makes developing TiDB a breeze. With this extension, developing a distributed system can be as easy as developing a local one.
