> the open source version of HBase has much lower adoption than Cassandra so that was a big factor

Is this due to the availability of experienced developers or another factor?

PostgreSQL has a lower adoption rate than MySQL, but we chose it due to its suitability to the tasks at hand. As long as the adoption rate is not low enough to give concern about the longevity of a tool, I'm less concerned about it than other factors.

Well, relatively speaking Postgre might have lower adoption than MySQL, although I am not too sure about it. However, if you look at the absolute numbers, Postgre has huge adoption, even if it is smaller than MySQL's. So it doesn't really matter as chances are, you will able to find an experienced developer. Can't say the same about HBase, etc since there are significantly fewer projects requiring it compared to MySQL/Postgre.
