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.

History

[edit]

The predecessor Redis 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 Redis company suddenly switched the licensing for the Redis core code repository from the BSD license to proprietary licenses.[25] This prompted a large portion of the user and developer community, led by the Linux Foundation,[26] to fork the code under the new name Valkey, retaining the BSD license, [3] Valkey's candidates for release 8.0, five months after the fork, improved its threading and significantly improved its performance.[27][28]
