Options
set at the session level only apply to queries that you run during the current Drill connection. Session level
settings override system level settings.
NOTE that currently, the effects of deleting a short lived option (see <a href="../../../../../../org/apache/drill/exec/server/options/OptionValidator.html#isShortLived--"><code>OptionValidator.isShortLived()</code></a>) are
undefined. For example, we inject an exception (passed through an option), then try to delete the option, depending
on where the exception was injected, the reset query could either succeed or the exception could actually be thrown
in the reset query itself.</div>
