If anyone is interested in a Rust-based on-disk KV store, I've come across sled[0] a few times, seems interesting. The author's also built a lot of other cool concurrency primitives for Rust as well.

See my previous comment. Sled was considered, and it was the main KV storage in early implementation.

I kept the adapter approach in the code, so switching back to sled should be pretty easy (or even converting it to full in-memory)
