I agree! In order to leverage the power of NoSQL databases you have to
write your code accordingly and apply patterns that are fundamentally
different from the ones adopted with relational databases; also, NoSQL is a
rather large group that contains different families of products that
require different handling.
For all of these reasons I don't think that porting the entity engine to a
NoSQL database, while technically possible, would be actually useful.

Hi,
There are several TLPs which are *more or less* leveraging NoSQL databases with
SQL, at least: Apache Drill, Apache Hive, Apache Impala
They have JDBC drivers, but I don't know how much of SQL they support.
Of course there are also other not Apache solutions: Presto (Facebook), Dremel
(Google), ...
One of them, Trafodion (initially from HP), is in incubation for 2+ years:
http://trafodion.apache.org/
Here is a simple, clear answer about its possible usage

There are JDBC and ODBC drivers for Trafodion which is based on HBase
