First, Nathan Hurst’s excellent Visual Guide to NoSQL Systems. There are the expected quibbles in the comments about CAP definitions and where particular projects belong, but I’m just going to say that even if some of the details were wrong – and I’m not saying they are – it’s great to have such a handy map of the territory. I particularly like the use of color to represent orthogonal distinctions. Thanks, Nathan!

Second, Joe Landman’s “New” File systems worth watching. Joe’s take on Lustre vs. GlusterFS is pretty similar to my own, which I guess is not too surprising since Joe is one of the few people I’ve met who has real knowledge and experience with both. (Disclosure: I’ve been working with GlusterFS quite a bit at my day job, too.) Bit of a shame that he didn’t include PVFS2, though, since it’s also a worthy contender in this space. On the newer systems, he’s also spot on. Ceph is great stuff, and I look forward to playing with it more in the not-so-distant future. Tahoe-LAFS is the only thing out there addressing very high levels of security/confidentiality in a usable way, and Twisted Storage is a great data integration/consolidation platform. I’m not sure either of them really play in quite the same space as the others, so much as that they complement each other, but both are still worth looking into. I hope Zooko (who certainly reads here) and Chuck Wegrzyn (who probably does) don’t object to that characterization.

Lastly, something from me on Twitter.

First rule of distributed computing: split happens.

That got retweeted quite a bit, and one person even suggested a T-shirt. I’m rather proud of it, in a “still wouldn’t want it to be my claim to fame” kind of way.
