Sets expiry time on hash object.
HPEXPIRE key milliseconds [NX | XX | GT | LT] FIELDS numfields field [field…]
This command works exactly like HEXPIRE but the time to live of the key is specified in milliseconds instead of seconds. Note, that providing a millisecond time of ‘0’ will cause immediate expiration and reclamation of the field(s).
The HPXPIRE command supports a set of options that modify its behavior:
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 HASH, or key does not exist.
0: The specified NX | XX | GT | LT condition has not been met.
1: The expiration time was applied.
2: When called with 0 seconds.
O(N) where N is the number of specified fields.
