What is Redis?

Redis is a key-value database, primarily used as an in-memory database, cache and message broker.

Designed for fast performance, Redis is capable of handling large amounts of data, making it a popular choice for applications requiring very fast response times. In fact, unlike traditional disk-based databases, Redis stores data directly in memory, making it extremely fast for reads and writes.

Redis and Memcached are similar and both allow cache flushing, but Redis offers better memory management.
Enabling them does not change anything as such, unless a use is made of them, in a CMS or in a client-created application.

How to Activate Redis

From the context menu account, choose Performance -> Redis, to open the dialog box of the same name:

The Path shows the user the complete network socket. When queried, statistics are displayed.
