Available since: 2.6.0
Time complexity: O(1)
This command works exactly like
EXPIRE but the time to live of the key is
specified in milliseconds instead of seconds.
PEXPIRE command supports a set of options since Redis 7.0:
NX-- Set expiry only when the key has no expiry
XX-- Set expiry only when the key has an existing expiry
GT-- Set expiry only when the new expiry is greater than current one
LT-- Set expiry only when the new expiry is less than current one
A non-volatile key is treated as an infinite TTL for the purpose of
NX options are mutually exclusive.
Integer reply, specifically:
1if the timeout was set.
0if the timeout was not set. e.g. key doesn't exist, or operation skipped due to the provided arguments.
