This is a design document describing the mechanics of joins in Druid. It is related to the initial join support proposal (apache/druid#8728) but covers different things: the proposal is more about motivation, design considerations, scope, and direction. This document is more about implementation.

Most active GitHub users (git.io/top)
The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.
Only first 1000 GitHub users according to the count of followers are taken. This is because of limitations of GitHub search. Sorting algo in pseudocode:
githubUsers
.filter(user => user.followers > 1000)
