HPERSIST key FIELDS numfields field [field...]

The HPERSIST remove the existing expiration on a hash key’s field(s), turning the field(s) from volatile (a field with expiration set) to persistent (a field that will never expire as no TTL (time to live) is associated).

valkey-protocol(7) Array reply: a list of integer codes indicating the result of setting expiry on each specified field, in the same order as the fields are requested.

• -2: Field does not exist in the provided hash key, or the hash key does not exist.
• -1: Field exists in the provided hash key, but has no expiration associated with it.
• 1: The expiration time was removed from the hash key field.

O(1) for each field assigned with TTL, so O(N) to persist N items when the command is called with multiple fields.
