Redis PEXPIRE Command

Redis Keys

The Redis PEXPIRE command works similarly to the EXPIRE command, but it sets the time-to-live of a key in milliseconds, rather than in seconds as the EXPIRE command does.

Syntax

The basic syntax of the Redis PEXPIRE command is as follows:

PEXPIRE key milliseconds

Available Versions

>= 2.6.0

Return Value

Returns 1 if set successfully.

Returns 0 if the key does not exist or the setting fails.

Example

First, create a key and assign a value:

redis> SET mykey "Hello"
"OK"
redis> PEXPIRE mykey 1500
(integer) 1
redis> TTL mykey
(integer) 1
redis> PTTL mykey
(integer) 1498
redis>
