Summary: Execute single-node CTE plans
Key: IMPALA-13533
URL: https://issues.apache.org/jira/browse/IMPALA-13533
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Michael Smith
Assignee: Michael Smith
Add backend support for CTE plans.
* Add PlanNode/ExecNode for CTE producer, consumer, and sequence nodes.
* Implement backend node-local dataflow from CTE producers to consumers. Use
BufferedTupleStream to buffer CTE producer results until each consumer is ready
to process them; initially this will be a batch operation, where CTE producer
puts all results into the BufferedTupleStream, then consumers can start reading
them.
* Should be able to execute all TPC-DS queries.
