WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
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.
Born off of that, came LevelDB (2011) by the same authors which uses LSM Tree as its underlying data structure. This gave rise to pluggable storage engines and embedded databases. Around the same time in 2007, Amazon came up with DynamoDB which uses the same underlying LSM Tree structure along with a masterless distributed database design.
