Valkey is an open-source in-memory storage, used as a distributed, in-memory key–value database, cache and message broker, with optional durability.[8] Because it holds all data in memory and because of its design, Valkey offers low-latency reads and writes, making it particularly suitable for use cases that require a cache. Valkey is the successor to Redis, the most popular NoSQL database,[9][10][11] and one of the most popular databases overall.[12] Valkey or its predecessor Redis are used in companies like Twitter,[13][14] Airbnb,[15] Tinder,[16] Yahoo,[17] Adobe,[18] Hulu,[19] Amazon[20] and OpenAI.[21]
Valkey supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indices.
The project was developed and maintained by Salvatore Sanfilippo, starting in 2009.[22] From 2015 until 2020, he led a project core team sponsored by Redis Labs.[23]
In 2018, Redis Ltd., the company managing Redis development, licensed some modules under the proprietary SSPL.[24] In 2024, the company suddenly switched its main Redis code from the BSD license to proprietary licenses.[25] This prompted a large portion of the user and developer community to fork the code under the new name Valkey, retaining the BSD license.[3]
