Re: [RELEASE] 0.8.0
Is there anyone willing to upgrade the libcassandra for C++, to support new features in 0.8.0? Or has anyone started to work on it?

Re: [RELEASE] 0.8.0
Of course I talked too soon. I saw a corrupted commitlog some days back after killing cassandra and I just came across a committed hints file after a cluster restart for some config changes :( Will look into that. Otherwise, not defaults, but close. The dataset is fed from scratch so yes, memtable_total_space is there. Some option tuning here and there and a few extra GC options and a relatively large patch which makes more compact serialization (this may help a bit...) Most of the tuning dates back to cassandra 0.6/0.7. It could be an interesting experiment to see if things got worse without them on 0.8. Hopefully I can submit the serialization patch soon.

How did that typo happen... across a committed hints file should be across a corrupted hints file Seems like the last supercolumn in the hints file has 0 subcolumns.

Re: [RELEASE] 0.8.0
Yes, I am aware of it but it was not an alternative for this project which will face production soon. The patch I have is fairly non-intrusive (especially vs. 674) so I think it can be interesting depending on how quickly 674 will be integrated into cassandra releases. I plan to take a closer look at 674 soon to see if I can add something there.

So why am I resorting to hyperbole? Well, for one because this is the release that debuts the Cassandra Query Language (CQL). In one fell swoop Cassandra has become more than NoSQL, it's MoSQL. Cassandra also has distributed counters now. With counters, you can count stuff, and counting stuff rocks. A kickass use-case for Cassandra is spanning data-centers for fault-tolerance and locality, but doing so has always meant sending data in the clear, or tunneling over a VPN. New for 0.8.0, encryption of intranode traffic. If you're not motivated to go upgrade your clusters right now, you're either not easily impressed, or you're very lazy. If it's the latter, would it help knowing that rolling upgrades between releases is now supported? Yeah. You can upgrade your 0.7 cluster to 0.8 without shutting it down. You see what I mean? Then go read the release notes[1] to learn about the full range of awesomeness, then grab a copy[2] and become a (fashionably )early adopter. Drivers for CQL are available in Python[3], Java[3], and Node.js[4]. As usual, a Debian package is available from the project's APT repository[5]. Enjoy!
