If you would just want to limit it to a max of 1000 regardless of their being no limit. I believe hash tables always add more items to the "end" so you could just remove the first item in the table. Which you can get the name by using $hget(tablename,1).item
No a hash table is an unsorted structure, there is no beginning or end. $hget(tablename, 1).item will return an arbitrary item completely unrelated to the order it was added.
