Possibly not clear from the title: 2.4.0 final was just released. All the new users are strongly encouraged to use this instead of 2.2.x. Existing users should plan an upgrade to 2.4 if possible in order to take advantage of the new features. A list of improvements is available here: http://antirez.com/post/everything-about-redis-24.html http://antirez.com/post/everything-about-redis-24.html

  Great news. The 2.4 rc11 release has been stable in my experience, I'm looking forward to the update. Thank you for all your work on redis.
  - antirez 15y ago
    Thanks, it is quite a lot of time we don't have a bug report for 2.4 that is severe or not in common with the 2.2 code base, so we decided to release it as stable. We also have big users already using 2.4. However now that it is the default download I expect 2.4 to be more stressed :)

      when do we get support for lua/scripting in redis?
      - antirez 15y ago
        Either 2.6 that is the current unstable -cluster +scripting, or possibly 3.0 will ship directly with both cluster and scripting.
        aaronblohowiak 15y ago
        Please don't wait for 3.0 for scripting, using it in unstable has been very effective for me.
        antirez 15y ago
        Ok, I'll try to push forward the plan for 2.6 as hard as I can. I'm sure shipping 2.6 and 3.0 is a bit more time consuming than shipping everything into 3.0, but actually it can be worth it. Thanks for your feedback :)
        toisanji 15y ago
        will the scripting work in clustering mode the same way it would work with a single redis instance?

  Also possibly not clear from the title: that it's about redis. I was a bit confused (though it worked as click-bait)

  Definitely not clear from the title: This is Redis 2.4.0.

  Redis is one of the most stable components of our architecture -- thanks for the great work. We're probably going to run it as a slave for awhile w/ a 2.2 master -- will be interesting to see how much memory we save, especially with copy-on-write improvements.

    We have been running redis in production for months now and have never ever had a SINGLE problem with it. This, all while doing 17,000+ commands per second!
  - willbmoss 15y ago
    Just as a word of warning, Redis 2.2 cannot read rdb or aof files created by 2.4 (meaning I'm pretty sure 2.2 can't be a slave of 2.4. So, if you have a fail over scenario, you might be forced to upgrade your master to 2.4.
    - sehugg 15y ago
      Good point. Hopefully karma will shine upon us :)

  Is there an official Ubuntu PPA repo, that serves the latest redis version. I did find some here, but they look older?: https://launchpad.net/ubuntu/+ppas?name_filter=redis https://launchpad.net/ubuntu/+ppas?name_filter=redis
  - NyxWulf 15y ago
    The repos update too slowly for them to be up to date on Redis, at least at the current pace Redis is moving at. You can find the latest build here: http://redis.io/download http://redis.io/download it's pretty simple to build and install. Setting up a production environment takes a few more steps. Here are a couple of posts that will get you there: http://www.denofubiquity.com/nosql/412/ http://www.denofubiquity.com/nosql/412/ http://jramirez.tumblr.com/post/2589232577/prime-time-redis-101-set-up http://jramirez.tumblr.com/post/2589232577/prime-time-redis-... Those are both written for 2.2, but my config still works fine with 2.4 using settings derived from those posts.

2.4.0 release of what? might want to put something more in the title
- antirez 15y ago
  I think the author forgot "Redis" when editing the title to add "final".

I upgraded my production server to Redis 2.4 and saw a MASSIVE decrease in memory usage. 11.7GB to 3.6GB. I wrote up a blog post about it: http://cosmicrealms.com/blog/2011/10/03/massive-decrease-in-memory-usage-with-redis-2-dot-4/ http://cosmicrealms.com/blog/2011/10/03/massive-decrease-in-...

  One thing you don't note in your post (but made a big difference for us) is that 2.4 uses jemalloc. This reduced memory fragmentation for us by around 25%.

Yesterday I was working on getting redis setup on a windows box. First time I have ever used it. There was a service config error on my part but before I figured it out I posted to twitter with a little passive aggressive spot asking "redis, why can't we just be friends?" Almost immediately after posting the tweet I figured out what was going on, and made the correction. Less than 12 min later I get a reply on twitter from some guy named @antirez asking if he could help. I mentioned to him that I already figured out what was up but thanked him regardless. A few min later he replied that if I needed anything else to let him know. I have asked for and received help on topics before on twitter, but never really had anyone contact me after I was just kinda being an ass. http://twitter.theinfo.org/124568006838845440 http://twitter.theinfo.org/124568006838845440 last night I looked up @antirez and found he is (one of?) the authors of redis. I can see confirmation here with his notes on this post. Now that I know it was a day before a release his offer makes me smile even more. Kudos to he (and his team?). The overt gesture stuck with me since and made me much more willing to help out other people. Congrats on release and just being an all around nice guy yesterday to some guy whom you had never met and who was being a bit snarky.

  Redis has more than one contributors, but the founder and lead developer of Redis is Salvatore Sanfilippo aka @antirez. He is clearly a programming God.
- willbmoss 15y ago
  We (Bump) have found two bugs in Redis and both times we've worked closely with Salvatore and had them fixed in less than 48 hours. He's a great programmer who really cares about the product.
maushu 15y ago
It's a shame that Redis development is focused more on keeping the data on memory than using the hard drive. Really bad for people like me that use VPSes with low memory but decent hd space. (eg: 512MB RAM vs 20GB HD)
- gtuhl 15y ago
  I think the focus on in-memory only is what makes Redis great and I hope they never change. It lives on that requirement and is incredibly stable and fast. I don't want another half-baked data store that technically "works" on disk but only as long as your volume is completely trivial. There are plenty of those if capacity is a dominating concern.

@antirez and the Redis team. Thank you for the wonderful work you do. Redis is an integral part of our infrastructure, and we have truly enjoyed working with it.
