Top-notch cache invalidation on Acquia Cloud!

The acquia_purge module invalidates your Varnish caches on your Acquia Cloud site. When combined with setting Drupal's time to live (TTL) very high, your stack requires less servers, becomes much more resilient against DDOS attacks and performance dramatically improves!

When do I need this?

Although we recommend every Acquia Cloud customer to use this module, you will absolutely need to start using it when any of these things sound familiar:

  • You're often getting the infamous Temporary Unavailable error.
  • Pages are often slow and take more than 2-3 seconds to load.
  • Traffic peaks quickly take down your site.
  • You have many web servers and would like to reduce costs.
  • Heavy processing (e.g. slow queries, cron imports) take your site down.

What time does it take?

Drupal 8 site owners have a true turn-key experience as the module integrates heavily with the purge cache invalidation framework and should be finished within minutes, get started with the installation instructions.

Drupal 8 testing program!

The Drupal 8 version is currently being tested by a select group of Acquia Clients, so that we learn what it does to hardware requirements and find potential bugs and quirks. Everyone with a production environment is more than welcome to join our program, just file a support ticket or ask your Acquia representative!

We're currently in private beta, which means you can't just download and enable the module just yet... Once we're through this phase, the public beta will follow, leading up to release candidates and a stable version for all.

Drupal 7

Owners of Drupal 7 sites are advised to schedule at least one day of testing and tuning to ensure that every section of their site is covered, as the expire module won't cover everything and requires them to set up rules. See its README, installation instructions and especially its domains documentation.
