RocksDB logo

RocksDB is a high performance embedded database for key-value data. It is a fork of LevelDB which was then optimized to exploit many central processing unit (CPU) cores, and make efficient use of fast storage, such as solid-state drives (SSD), for input/output (I/O) bound workloads.

RocksDB is used in production systems at various web-scale enterprises including Facebook, Yahoo!, and LinkedIn.
