SETEX

Syntax

1. SETEX key seconds value

Time complexity: O(1)

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:

1. SET mykey value
2. 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.

Return

Simple string reply

Examples

1. dragonfly> SETEX mykey 10 "Hello"
2. "OK"
3. dragonfly> TTL mykey
4. (integer) 10
5. dragonfly> GET mykey
6. "Hello"
