PERSIST

Remove the existing timeout on key, turning the key from volatile (a key with an expire set) to persistent (a key that will never expire as no timeout is associated).

Examples

127.0.0.1:6379> SET mykey "Hello"
OK
127.0.0.1:6379> EXPIRE mykey 10
(integer) 1
127.0.0.1:6379> TTL mykey
(integer) 10
127.0.0.1:6379> PERSIST mykey
(integer) 1
127.0.0.1:6379> TTL mykey
(integer) -1
