Rocksdb

RocksDB is a high-performance key-value store library developed at Facebook for use in their web servers, and later released as an open-source project. It's based on Google's LevelDB and optimized to exploit more recent hardware features. RocksDB uses a log-structured merge-tree (LSM) storage engine that enables fast random writes while supporting efficient read operations through background compactions. The database technology is written in C++ and provides a flexible API with support for various platforms, including Linux, Mac OS X, Windows, and Android. RocksDB has been designed to handle extreme scenarios where large amounts of data must be stored while maintaining low latency for both read and write operations. Its performance makes it suitable for managing stateful applications such as distributed systems or caching layers where fast access to data is necessary without sacrificing durability.
