How to Install Redis Database on Ubuntu 22.04 & Linux Mint

Redis (Remote Dictionary Server) is an open-source key-value data store that allows users to use this database as a cache on top of other databases to improve the performance of the applications. It serves as server-client architecture, which means that it can run as a service in the background so that the client can query it. It has two columns, one for the key and the other for the value. In terms of performance, it runs better than other databases such as MySQL, MariaDB or PostgreSQL.
