AgateDB is an embeddable, persistent and fast key-value (KV) database written in pure Rust. It is designed as an experimental engine for The TiKV project that will bring aggressive optimizations for TiKV specifically.
AgateDB is still under early heavily development, you can check the development progress at the Project.
The whole plan is to port badger in Rust first and then port the optimizations that have been made in unistore.
X is a great project! The motivation of this project is to land the optimizations we have been made to unistore in TiKV finally. Unistore is based on badger, so we start with badger.
Using Rust because it can bring memory safety out of box, which is important during rapid development. TiKV is also written in Rust, so it will be easier to integrate with each other like supporting async/await, sharing global thread pools, etc.
