Valkey

Valkey is an open-source in-memory key–value database, used as a distributed 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 a fork of Redis, the most popular NoSQL database and one of the most popular databases overall.[9][10][11][12] Valkey and Redis have been used by companies including Twitter,[13][14] Airbnb,[15] Tinder,[16] Yahoo,[17] Adobe,[18] Hulu,[19][20] Amazon[21] and OpenAI,[22] and Valkey is supported by Alibaba Cloud, AWS, Ericsson, Google Cloud, Heroku, Oracle, Percona, and Verizon.[23]

History

edit

Redis was developed and maintained by Salvatore Sanfilippo, starting in 2009.[24] From 2015 until 2020, he led a project core team sponsored by Redis Labs.[25]

In 2018, Redis Ltd., the company managing Redis development, licensed some modules under a modified Apache 2.0 with a Commons Clause.[26][27]

In 2024, the Redis company switched the licensing for the Redis core code repository from the BSD license to dual SSPL and proprietary licensing.[28] This prompted a large portion of the user and developer community, including contributors from Alibaba Group, Amazon, Ericsson, Google, Huawei and Tencent, to fork the code of Redis 7.2.4 as a project of the Linux Foundation under the new name Valkey,[4] retaining the BSD license.[3] Valkey 8.0, released six months after the fork, featured improved threading and significantly improved performance.[29][30]
