At last week’s Data@Scale event, Facebook announced support for RocksDB, a high-performance, embedded key-value store database optimized for flash storage.
Facebook said RocksDB builds on LevelDB to be scalable to run on servers with many CPU cores, to efficiently use fast storage, to support IO-bound, in-memory and write-once workloads, and to be flexible to allow for innovation.
