Tracks the timestamps of the most recent updates to particular tables. It is important that the cache timeout of the underlying cache implementation be set to a higher value than the timeouts of any of the query caches. In fact, we recommend that the the underlying cache not be configured for expiry at all. Note, in particular, that an LRU cache expiry policy is never appropriate.
