Acquia’s require line sets a per-environment temporary directory location for compiled Twig templates.

Cloud Platform stores all Twig caches for all websites hosted in an environment in the following directory:

/mnt/tmp/[SITENAME]/php_storage/twig/[GITREF]/[DATABASE_ROLE]

• [SITENAME]: Your application’s sitename.
• [GITREF]: The Git reference of the branch or tag deployed to an environment.
• [DATABASE_ROLE]: A website-specific identifier, based on the database.

Separating Twig caches by commit and website allows Cloud Platform to purge unused Twig cache directories, preventing them from filling up ephemeral storage on busy infrastructure that frequently deploy code requiring many Twig cache files.

Cloud Platform limits maximum request time to 600 seconds. Outdated Twig cache directories are removed 700 seconds after a code deployment completes, ensuring no active processes still need access to older Twig cache directories.

Altering Twig cache directories

To alter the Twig cache storage directory, overwrite the value for $settings['php_storage']['twig']['directory'] in your application’s sites/default/settings.php file after the Acquia settings require line, as shown in the following example:

// On Cloud Platform, this include file configures Drupal to use the correct
// database in each site environment (Dev, Stage, or Prod).
if (file_exists('/var/www/site-php')) {
   require('/var/www/site-php/mysite/mysite-settings.inc');
}
// Alter the Twig cache storage directory.
$settings['php_storage']['twig']['directory'] = '/mnt/tmp/mysite/php_storage/twig';

Twig caches with Site Factory-hosted sites

Twig caches for the websites hosted by Site Factory are stored in an environment in the following directory:

/mnt/tmp/[SITENAME]/php_storage/twig/[GITREF]/[DATABASE_ROLE]
