JSONiq - The JSON Query Language
Decades of Lessons Learnt JSONiq is a query language specifically designed for the popular JSON data model.

RocksDB | A persistent key-value store
High Performance RocksDB uses a log structured database engine, written entirely in C++, for maximum performance. Keys and values are just arbitrarily-sized byte streams. Optimized for Fast Storage RocksDB is optimized for fast, low latency storage such as flash drives and high-speed disk drives. RocksDB exploits the full potential of high read/write rates offered by flash or RAM. Adaptable RocksD
