RocksDB is a high performance[2][3][4][5][6] embedded database for key-value data. It is a fork of Google's LevelDB optimized to exploit multi-core processors (CPUs), and make efficient use of fast storage, such as solid-state drives (SSD), for input/output (I/O) bound workloads. It is based on a log-structured merge-tree (LSM tree) data structure. It is written in C++ and provides official language bindings for C++, C, and Java. Many third-party language bindings exist. RocksDB is free and open-source software, released originally under a BSD 3-clause license.[7][8][9] However, in July 2017 the project was migrated to a dual license of both Apache 2.0 and GPLv2 license.[10] This change helped its adoption in Apache Software Foundation's projects after blacklist of the previous BSD+Patents license clause.[11][12]

RocksDB is used in production systems at various web-scale enterprises[13] including Facebook, Yahoo!,[14] and LinkedIn.[15]
