KVS

KVS, or Key-Value Store, is a type of database that stores data as pairs: a unique key and its associated value. Think of it like an advanced dictionary where each word (key) maps directly to its definition (value). This structure allows for very fast data retrieval and updates because you can access any item directly with its key. KVS systems are widely used in applications needing quick access to large amounts of data, such as caching, session management, and real-time analytics, due to their simplicity and high performance.
