- Usage:
-
DEL key [ key ... ]
- 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).
- Since:
- 1.0.0
Removes the specified keys. A key is ignored if it does not exist.
Examples
127.0.0.1:6379> SET key1 "Hello"
OK
127.0.0.1:6379> SET key2 "World"
OK
127.0.0.1:6379> DEL key1 key2 key3
