Are expired caches automatically removed if no cache regeneration is set?

    Hi @telsenome

    We use the WordPress transient API to save the caches. By default these transient are saved to the database and WordPress clears expired transients on (I believe) a daily interval.
    Now if you are using some sort of external object cache (like Redis or Memcached) the transients are stored outside of the database and WordPress doesn’t clear them. However most external object cache implementations do have some sort of garbage collection.
