> Today, the only way to run a query in distributed way in Drill is to manually insert
exchange operators into a physical plan, and submit the physical plan to Drill.  
> We will add a set of  new optiq rules to insert exchange operators to the physical plan
automatically.  The end user can submit a SQL statement directly to Drill, and the Drill optiq
rules will insert the exchange operators when certain conditions are met. The resulting physical
plan will be executed in distributed way on multiple Drillbits.
