This command works exactly like EXPIRE but the time to live of the key is specified in milliseconds instead of seconds.

Options #

The PEXPIRE command supports a set of options since Redict 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 GT and LT. The GT, LT and NX options are mutually exclusive.
