I’ve been diligently studying database internals, data structures, and more for almost two years now, writing many different things. This open-source key-value store is built on top of a log-structured merge tree, inspired by WiscKey and LevelDB. It's fairly fast, durable and rather efficient. It's meant to provide you a persistent embedded storage option for binary key value pairs.
