This is a sql relational database implemented in rust. Here you will find a from scratch implementation of a RDBMS with a Buffer Pool Manager (like PostgreSQL). You will find a LRU-K implementation of the cache (MRU implementation is under investigation for OLAP) since we do OLTP at present. You will find an MVCC implemention (in-progress), and Query Planner (in-progress).
If you are interested in how this project has evolved and how it is envisioned to grow, along with graphics, please see the blogs at Concurrency Corner, my personal blog about concurrent systems.
Please feel free to contribute should you desire to.
