iredis/iredis/data/commands/setex.md

Set key to hold the string value and set key to timeout after a given number of seconds. This command is equivalent to executing the following commands:

SET mykey value
EXPIRE mykey seconds

SETEX is atomic, and can be reproduced by using the previous two commands inside an MULTI / EXEC block. It is provided as a faster alternative to the given sequence of operations, because this operation is very common when Redis is used as a cache.

An error is returned when seconds is invalid.
