--------------------------------
Summary: Insert Exchange operators automically in physical plan,
in order to execute query in distributed way.
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
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.
