This seems like a nice addition. I would love to see conditional writes eventually as well. I wonder if cassandra ends up evolving into something that looks kind of like a database. It's definitely taken some steps in that direction before this. I haven't read the paper yet, but Google's spanner gives me hope that at some point in the near? future I won't have to worry about the details of consistency myself anymore.

That's a pretty concise way of expressing why we started building our product here at FoundationDB (http://foundationdb.com/). We're building a distributed key-value store with ACID transactions precisely so that developers building cool projects can stop worrying about all of the ins and outs of maintaining consistency by hand. If you'd like to give it a try, please feel free to sign up for our alpha -- it's just a quick form on our website (http://foundationdb.com/#get) and then you're welcome to download the software and check it out.
