interface CacheOptionalInterface

Indicates that caching is optional.

This interface can be used to suggest that certain implementations are fast enough that they do not require additional caching.

If and how exactly this is implemented and used depends on the specific system.

Examples:

• If all active access policies implement this interface, \Drupal\Core\Session\AccessPolicyProcessor will skip the persistent cache.
