DEL

DEL key [key ...]

Available since 1.0.0.

Time complexity: 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).

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

Return value

Integer reply: The number of keys that were removed.

Examples

redis> SET key1 "Hello" "OK" redis> SET key2 "World" "OK" redis> DEL key1 key2 key3 (integer) 2
