Database 101: How to Model Leaderboards for 1M Player's Game.
Then I decided to talk to my boss and ask him if I could work with the YARG guys and the condition was to create something cool enough to implement ScyllaDB (NoSQL Wide-column Database) since I'm working as a Developer Advocate there. You won't believe how the simplicity and scalability brought by ScyllaDB perfectly fit the needs of YARG.in!

Take Advantage of Git Rebase
What you say is impossible, we pretty successfully apply at ScyllaDB (see https://github.com/scylladb/scylladb/commits/master).
I'm not sure 100% of the commits compile & pass all tests - there may be some mistakes - but generally we're in a pretty good state, and the clean git log is being successfully used for bisecting.
If you want even larger scale - if I understand correctly, the Linux kernel practices a similar thing, which is where we got this practice from (ScyllaDB founders came from kernel development). And since Git was originally created to help developing Linux - that's where you want to look for good practices.
