AFAICT this would mean introducing and maintaining a layer that
abstracts over RDBMSes and Cassandra. That's a big abstraction, over two
quite different systems, and it would be hard to write code that
performs well in both cases. If performance in this layer is critical,
then pick whichever DB architecture handles the expected query load
better and use that.
