set key with expire time

[Christopher Gokey]

I'm really liking redis the more that I get into it.    

Question.

Right now, I'm using:

connection.set(key, value);

I noticed that a third argument can be added, SetArgs....

Trying to find documentation that will allow me to set an expire timestamp at the time of the set, my guess is it is SetArgs, how would i use this?   

SetArgs args = SetArgs.ex(60*60)); // set for 60 minutes

It isn't possible to auto expire keys at a certain value is there?

Thanks,

Chris

Hi Chris, 

glad to hear that.

lettuce is a low-level Redis driver that uses the same command terminology as Redis does. The set command in particular is documented here [0] and you can use [1] px (milliseconds) or ex(seconds) as expiry values. You can find a lot of details on your questions within the Redis docs [2].

There are also Redis clients which provide an API on a higher abstraction level [3] [4] [5]. Those libraries allow object mapping or annotation-driven expiry configuration.

Cheers, Mark
