Lists
A list is an isolated subset of keys stored in the shared memory of the cache system that can be manipulated at once as a group. For example, you might want store all cached objects related to the user with id 214 in a list named user_214, like this:
$userId = 214;
$cacheListName = "user_".$userId;
$e->Cache->huge->listSet($cacheListName, "numberOfVisits", $numberOfVisits);
$e->Cache->huge->listSet($cacheListName, "numberOfFollowers", $numberOfFollowers);
$e->Cache->huge->listSet($cacheListName, "numberOfLikes", $numberOfLikes);
Now, when you want to clear the entire cache for a specific user, you don't have to remember all the cache keys you used for that user, you just clear the entire list:
foreach ($e->Cache->huge->listGetAll($cacheListName) as $listKey)
$e->Cache->huge->listDel($cacheListName, $listKey);
Check Lists methods to see more ways to interact with cache lists.
