There are many kinds of databases, I've used similar designs to [0] (Lisp warning, ymmv) successfully in several projects.

I have a fairly comprehensible left leaning rb tree implementation that I've been porting along my travels.
I keep it around for situations where a binary searched array isn't doable or good enough, but I still want ordered set functionality that isn't in the stdlib.

I recently implemented the Bitcask paper in Golang and shared my learnings [on this post](https://mrkaran.dev/posts/barreldb/).
[GitHub](https://github.com/mr-karan/barreldb/) repo if interested.
Bitcask is an excellent paper that is not overwhelming to understand and offers a great stepping stone in building your own data stores. The simple yet powerful design of an append only file is eloquent and performant.
I’d love to read about more such implementations, if anyone has any recommendations.
