Configuring Redis caching in Magento
What is object caching?
An object cache stores the results of expensive and/or frequent database queries in a way that makes them easy to retrieve, and eliminates the need for repeated access to the database. Object caching greatly reduces the time it takes to retrieve query results.
What is Redis?
Redis (Remote Dictionary Server) is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker.
It supports data structures such as strings, hashes, lists, sets, range queries, bitmaps, hyper loglogs and geospatial indexes with radius queries.
In its simplest form, Redis is a caching system that can be combined with MySQL or MariaDB to optimize the application level speed.
How do I enable Redis?
We have a separate guide that covers enabling Redis on your Premium PCI-DSS compliant hosting account (Link opens in a new tab).
