- Usage:
-
HPTTL key FIELDS numfields field [ field ... ]
- Complexity:
- O(1) for each field assigned with TTL, 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 milliseconds.
Like HTTL this command returns the remaining time to live of hash field(s) that has an associated expiration time,
with the sole difference that HTTL returns the amount of remaining
time in seconds while HPTTL returns it in milliseconds.
See also the HTTL command that returns the same information with seconds resolution.
Examples
127.0.0.1:6379> HSET myhash f1 v1 f2 v2 f3 v3
(integer) 3
27.0.0.1:6379> HPEXPIRE myhash 10000 FIELDS 2 f2 f3
1) (integer) 1
2) (integer) 1
127.0.0.1:6379> HPTTL myhash FIELDS 3 f1 f2 f3
1) (integer) -1
2) (integer) 9597
3) (integer) 9597
RESP2/RESP3 Reply
Array reply: a list of values associated with the result of getting the remaining time-to-live of the specific fields, in the same order as they are requested.
