Upgrade to a different version?

2011-03-16 Thread Jake Maizel
We are running 0.6.6 and are considering upgrading to either 0.6.8 or one of the 0.7.x releases. What is the recommended version and procedure? What are the issues we face? Are there any specific storage gotchas we need to be aware of? Are there any docs around this process for review? Thanks,

Hi Jake, I'm sending this privately, because I wanted to tell you my opinion frankly. I don't know about the .6 series or .74, but so far, all of the .7 series of cassandra has been a disaster. I would think twice about switching to anything in .7 series to production until things stabilize and

Sorry guys, that was meant to be private. My opinion stands, but I didn't want to hurt any of the dev's feelings by being too frank. I think the progress has been good in new features, but I feel we have taken a step back in relability and scalability since so many features were added without ade

Paul, Don't feel like you have to hold back when it comes to feedback. There is a place to vote on releases. If you have something that could potentially be critical that you can isolate, by all means chime in. Even if your vote isn't binding if you are not a committer, votes with something

I'm at a crossroads right now. We built an application around .7 and the features in .7, so going back to .6 wasn't an option for us. Now, we are in the middle of setting up dual mysql and cassandra support so that we can "fallback" to mysql if Cassandra can't handle the workload properly. It's

As for the version, we will wait a few more days, and if nothing really bad shows up, move to 0.7.4. On Thu, Mar 17, 2011 at 10:40 PM, Thibaut Britz < thibaut.br...@trendiction.com> wrote: > Hi Paul, > > It's more of a scientific mining app. We crawl websites and extract > information from thes

Hi Paul, It's more of a scientific mining app. We crawl websites and extract information from these websites for our clients. For us, it doesn't really matter if one cassandra node replies after 1 second or a few ms, as long as the throughput over time stays high. And so far, this seems to be the

Do people have success stories with 0.7.4? It seems like the list only hears if there's a major problem with a release, which means that if you're trying to judge the stability of a release you're looking for silence. But maybe that means not many people have tried it yet. Is there a record of t
