Hi, It does not matter that a slabs contain several pages, as it dump all the keys in the LRU list in the slab. But the maximum dump memory is 2M, so it is possible that not all the keys in the slab are dump. (Of course you can change this limitation in function do_item_cachedump).
Another approach I heard it is that save the keys in a database when setting it to the cache. So you can easily remove keys as any pattern. That is a good idea if there are not so many keys adding and deleting operation. Hope it help u.

For example we want to remove all the key as "my_key_ *?" We try to parse all the slabs with the command "stats cachedump" but our slabs contain several pages and it is impossible to recover all the elements!
