SETEX key seconds value
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.
