Julian Hyde commented on DRILL-105:
-----------------------------------
Consider using Optiq's JDBC adapter. There is quite a lot of complexity: how to
flatten the algebra tree into a small number of query blocks, how to map data
types, how to know which built-in functions are supported in the target
database.

> We should allow query pushdown into JDBC. Note that this is very different
> from JDBC support that allows a Java program to send a query to Drill.
> Instead, it is a way for Drill to push down a query into a JDBC driver.
