Steven Hawkins commented on TEIID-4213:
---------------------------------------

So then we need a method to manually set the server version for Cassandra, cut off support for versions older than 2.2, or push this change to 9.2 as well.

> Cassandra supports basic aggregate functions:
> MIN(),MAX(),SUM() and AVG()
> Currently Teiid doesn't push such queries.
> NOTE:In case of AVG() there is difference between the values returned from Teiid vs. Cassandra for an integer column. Cassandra returns only whole part of the number as integer, Teiid returns bigdecimal.
