What is the most solid version of Cassandra? No secondary indexes needed.
Hello, we are acquiring new hardware for our cluster and will be installing it soon. It's likely that I won't need to rely on secondary index functionality, as data will be write-once read-many and I can get away with inverse index creation at load time, plus I have some more complex indexing in mind than comes packaged (too much to explain here). So, if I don't need indexes, what is the most stable, reliable version of Cassandra that I can put in production? I'm seeing bug reports here and some sound quite serious, I just want something that works day in, day out.

Re: What is the most solid version of Cassandra? No secondary indexes needed.
0.7.1 is what I would go with right now. It's likely you'll eventually have to upgrade that as well, but moving to other 0.7.x releases should be fairly painless. Most development is happening on the 0.7 releases, which already have lots of fixes over the 0.6 series (not to mention performance improvements and better logging in general).

Re: What is the most solid version of Cassandra? No secondary indexes needed.
Thank you! It's just that 7.1 seems the bleeding edge now (a serious bug fixed today). Would you still trust it as a production-level service? I'm just slightly concerned. I don't want to create a perception among our IT that the product is not ready for prime time. -- View this message in context: http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/What-is-the-most-solid-version-of-Cassandra-No-secondary-indexes-needed-tp6028966p6029047.html Sent from the cassandra-u...@incubator.apache.org mailing list archive at Nabble.com.
Re: What is the most solid version of Cassandra? No secondary indexes needed.
We have been running a 0.6.3 with some custom features for more than 1 month and it has been running fine. we are planning on moving to 0.7.1 in about 1 month from now if it past our stress tests. If you are really going from scratch to production environment, I would definetly go with 0.7.1 after some heavy stress test, it will give you a better migration process to any new version.

You are not going to want to go through the 6.X API to 7.0 API migration. I am still happily running 0.6.8 But I know I need the features in 0.7.X. If i were starting today I would go with the 0.7.X branch and be ready to do some minor updates in the next couple months.
Re: What is the most solid version of Cassandra? No secondary indexes needed.
0.6.8 is stable and production ready, the later versions of the 0.6 branch has issues. No offense, but the 0.7 branch is fairly unstable from my experience. I have reproduced all the open bugs with a production dataset, even when tried to rebuild it from scratch after a complete loss. If you have a few month before going to production your best bet is still 0.7.1 as it will stabilize but the switch between versions is painful. /Attila

Thank you Attila! We will indeed have a few months of breaking in. I suppose I'll keep my fingers crossed and see that 0.7.X is very stable.

I'm seeing bug reports here and some sound quite serious, I just want something that works day in, day out. Note : the following is my opinion only, and likely does not represent the view of the Apache Cassandra project. The most stable/production ready version of Cassandra is : 0.6.8 I have to say 0.6.8 instead of 0.6.6, because 0.6.8 contains the (0.6.7-era) patch from CASSANDRA-1676, without which streaming is broken. However.. 0.6.7 and 0.6.8 contain non-bugfix patches, and in 0.6.7's case there is a regression in that non-bugfix patch. Versions of the 0.6 branch above 0.6.9 contain still more non-bugfix patches and regressions. All extant 0.7 releases (0.7.0, 0.7.1) contain major bugs. The most stable/safe version is, therefore, likely to be 0.6.6+1676. If you are uncomfortable patching 1676 into 0.6.6 yourself, use 0.6.8. https://issues.apache.org/jira/browse/CASSANDRA-1676 =Rob
