> interest in NoSQL-style computation seemed to be on the wane<p>Well that's just ridiculous. With machine/deep learning and big data analytics unquestionably on the rise there is actually more demand for a heterogenous architecture. And since in these fields you are often doing lazy-schema application having tools that support this paradigm are important.<p>In fact what does seem to be on the rise is having SQL on top of NoSQL stores e.g. Phoenix/HBase, Spark SQL. And they support all of SQL 2003 which by the looks of it this doesn't.
