TL;DR

AI summary of the plugin's readme

WP Redis is for high-traffic WordPress sites, including those on the Pantheon platform, that need speed for logged-in users and dynamic page loads. It solves the need for a fast, persistent object cache that scales across multiple application instances by backing the WP Object Cache with Redis.

Frequently Asked Questions

Common questions about WP Redis

If you are concerned with the speed of your site, backing it with a high-performance, persistent object cache can have a huge impact. It takes load off your database, and is faster for loading all the data objects WordPress needs to run.

This plugin is for the internal application object cache. It doesn't have anything to do with page caches. On Pantheon you do not need additional page caching, but if you are self-hosted you can use your favorite page cache plugins in conjunction with WP Redis.

A page load with 2,000 Redis calls can be 2 full seconds of object cache transactions. If a plugin you're using is erroneously creating a huge number of cache keys, you might be able to mitigate the problem by disabling cache persistency for the plugin's group: wp_cache_add_non_persistent_groups( array( 'bad-actor' ) ); This declaration means use of wp_cache_set( 'foo', 'bar', 'bad-actor' ); and wp_cache_get( 'foo', 'bad-actor' ); will not use Redis, and instead fall back to WordPress' default runtime object cache.

There's a known issue with WordPress alloptions cache design. Specifically, a race condition between two requests can cause the object cache to have stale values. If you think you might be impacted by this, review this GitHub issue for links to more context, including a workaround.
