I don't think "all you hear" is accurate. Mongo and Cassandra have some truly huge deployments and the "horror stories" are a function of the number of deployments. Search "MySQL sucks" or "Oracle sucks" and you'll find much the same thing. It is a result of being (successfully) deployed so many places. As an aside, if you want confidence in your NoSQL solution, reading either the Mongo or Cassandra mailing lists is an excellent way to realize how focused, efficient and powerful those companies and communities are. Of all the NoSQL db lists I read, Cassandra is one of the lowest incident levels and when there is, no matter how esoteric, it seems like one of the Datastax guys or someone from the community is able to help them out. As for Mongo, the fact that Eliot and team still replies 100s of times a day to all the questions, even complex reports, is beyond impressive to me. I am just trying to frame your comment a bit; these projects have left the "cool, large-scale toy" category a long time ago and have many companies better their existence on them. Netflix currently has one of the largest global Cassandra deployments (US east-west and UK) and continue to move out of SimpleDB and move more and more into their own custom deployment.

Fair enough, they may have come along way. I worked on that project with a chap who happend to also be a cassandra contributor, but we still didn't dare go with cassandra back then. And mongodb feels more squid than varnish; its just an uneasy feeling I get when I follow their crazy technical journeys ;)

  Just to clarify; I am not saying you are wrong and trying to talk you into it, just didn't want other readers to come across that comment and throw them out the window especially if they are a good fit. That being said, I am a big believer in gut feelings and if yours is telling you the answer is elsewhere then it is probably right.
