HOW TO CONFIGURE REDIS IN DRUPAL AND IMPROVE PERFORMANCE

Honestly, I had pending to do an article telling what Redis is, why you should use it in your Drupal, and how easy it is to install it.

But today I have seen that escueladrupal.com has published a video and an article explaining it much better than I could do it. I leave them below the intro.

My case and experience using Redis

Briefly, Redis serves to move the entire Drupal cache system from Mysql to a better optimized and 100% in RAM.

That is, it improves the reading/writing of caches, decongests the database and as a result, the web is faster and can support more concurrent traffic.

I don't want to get long, so I'll make a summary.

I've been using Redis for several years in conjunction with Drupal, it works great and is very easy to install/configure.

Before that, I recommended using Memcache, but Redis seems to me to be a bit faster.

You probably can't use Redis if you use cheap shared hosting. But for me it's not a problem, I don't have any project that doesn't have its server.

Seriously, it is very noticeable to have Redis vs using the default Mysql caches.

Especially when you have a lot of caches and a lot of visits to the site.

For any other doubt, I recommend watching the article and video of https://escueladrupal.com/articulos/configurar-redis-drupal
