- Usage:
-
HTTL key FIELDS numfields field [ field ... ]
- Complexity:
- O(1) for each field, so O(N) for N items when the command is called with multiple fields.
- Since:
- 9.0.0
- ACL Categories:
- @hash, @read, @fast
-
-2: Field does not exist in the provided hash key, or the hash key is empty.
-
-1: Field exists in the provided hash key, but has no expiration associated with it.
-
Integer: The expiration time associated with the hash key field, in seconds.
The HTTL command returns the remaining time to live of hash field(s) with associated expiration time(s).
This introspection capability allows a Valkey client to check how many seconds a
given hash field will continue to be part of the hash object.
See also the HPTTL command that returns the same information with milliseconds resolution.
Examples
127.0.0.1:6379> HSET myhash f1 v1 f2 v2 f3 v3
(integer) 3
27.0.0.1:6379> HEXPIRE myhash 10 FIELDS 2 f2 f3
1) (integer) 1
2) (integer) 1
127.0.0.1:6379> HTTL myhash FIELDS 4 f1 f2 f3 non-exist
1) (integer) -1
2) (integer) 8
3) (integer) 8
4) (integer) -2
RESP2/RESP3 Reply
