> Key: DRILL-450
> URL: https://issues.apache.org/jira/browse/DRILL-450
> Project: Apache Drill
> Issue Type: Bug
> Reporter: Jinfeng Ni
> Assignee: Jinfeng Ni
> Priority: Critical
> Attachments: DRILL-450-exchange.patch, DRILL-450-opt1.patch
>
>
> 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.
