Facebook released RocksDB

Even Facebook Open Source stands upon the shoulders of giants. The Facebook Database Engineering Team just released RocksDB, a persistent key-value store for flash storage, based on LevelDB by Sanjay Ghemawat and Jeff Dean at Google.

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.
