What is special interest group?

The TiDB project is organized primarily into Special Interest Groups (SIG). Each SIG is comprised of members from multiple companies and organizations, with a common purpose of advancing the project with respect to a specific topic, such as Parser/Expression/Planner.

Goal

Our goal is to enable a distributed decision structure and code ownership, as well as providing focused forums for getting work done, making decisions, and onboarding new contributors.

Scope

Every identifiable subpart of the project (e.g., github org, repository, subdirectory, API, test, issue, PR) is intended to be owned by some SIG.

Goverance

For more details about sig governance, you can read this doc sig governance. And if you are new to tidb, and want to find a sig to start, this contribution mapfor sig may be helpful.
