Quick Introduction To Valkey

Redis (Remote Dictionary Server) is a popular in-memory key-value pair database that is often used as a distributed cache. On 2024-03-20, Redis announced that future versions of Redis will be released under dual source-available licenses and not longer the three-clause Berkeley Software Distribution (BSD). Thus, Valkey began as a fork of Redis 7.2.4 as a project of the Linux Foundation.

Storing key-value pairs in RAM allows for faster database speeds than accessing from storage drives. Valkey has master-replica replication, clusters scaling up to 100 nodes, supports different abstract data structures, including strings, lists, maps, sets, sorted sets, hyperloglogs, bitmaps, streams, and geo-spatial indices.

This tutorial install Valkey and its subpackage script for Redis conversion and symlinks. The PHP Redis extension will also be installed on the server. Finally a WordPress plugin that allows Redis to be used a cache will be installed and activated.

Valkey is an open-source, in-memory data structure store that can be used as a database, cache, and message broker.
