Redis : expiration on sorted set

[Wahyd Mnémoi]

Hi, sorry for my english, i'm not very fluent. About Redis, i wonder if there is a clean solution to set an expire time to a member of sorted set ?

Best regards,

You can't do that. But if you insert a current timestamp as your score and the rest of your values as your key, you can call ZREMRANGEBYSCORE periodically to delete members based on the score. You can do something like this with LUA:

    call.redis("ZREMRANGEBYSCORE", "my:list", 0,  os.time()-ARGV[1])



Then set ARGV[1] to the number of seconds till something expires.

Hi Wahyd,

Regrettably, no - expiry can only be set for keys. Perhaps someone from the forum will be able to help to solve the problem you are facing if you provide more details on what you're trying to achieve.

Cheers,

Itamar
