del.3valkey - Man Page

DEL key [key...]

Removes the specified keys. A key is ignored if it does not exist.

valkey-protocol(7) Integer reply: the number of keys that were removed.

O(N) where N is the number of keys that will be removed. When a key to remove holds a value other than a string, the individual complexity for this key is O(M) where M is the number of elements in the list, set, sorted set or hash. Removing a single key that holds a string value is O(1).
