What is a LSM Tree 🪵?
Inspired from LevelDB, Facebook forked LevelDB and created RocksDB (2012), a more concurrent and efficient key value store that uses multi-threaded compaction to improve read and write performance. Recently Bytedance, the company behind TikTok has also released a key value store called terakdb that improves over RocksDB. Sled is another embedded key value store in Rust, that uses a hybrid architecture of B+ Trees and LSM Tree (Bw Trees). These fall under the category of embedded data stores.
