Description: 

To save 5+ extra redis operations on most requests, redis can now treat invalidateAll() like a deleteAll(), this is an optimization in anticipation of the deprecation of this API in Drupal core.

To opt in to this, add $settings['redis_invalidate_all_as_delete'] = TRUE; to your settings.php.
