httl.3valkey - Man Page

HTTL key FIELDS numfields field [field​...]

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(3valkey) command that returns the same information with milliseconds resolution.

valkey-protocol(7) 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.

• -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.
• valkey-protocol(7) Integer: The expiration time associated with the hash key field, in seconds.

O(N) where N is the number of specified fields.
