1) JDBC Storage Plugin Issues

We discussed DRILL-4696.  Parth and Sudheesh suggested that even with the
change suggested in DRILL-4177, this particular problem may still result in
out of memory because the MySQL fetch size needs to be set at the statement
level instead of in the connect string.  Parth added a comment with this
suggestion in DRILL-4177.

Aside from the memory problem, the fact that the 4-way join isn't being
pushed completely to MySQL may be a limitation in the JDBC storage plugin.
The plugin doesn't seem to be taking into consideration the actual
underlying row count of the table.  Aman suggested possibly tweaking one of
the optimizer parameters as a short-term workaround to force all plans to
be fully pushed down.

2) 1.7 has been released in open source Apache!
