DRILL-5080 is the umbrella ticket. Attached to that = ticket is a design document that details both the issues we wish to = address and how we propose to address them. Please have a look at the design and offer suggestions. In particular, = if any of you have experience with this operator, your insight into the = revised design would be very helpful. Thanks, - Paul Jira link: https://issues.apache.org/jira/browse/DRILL-5080=
