Matt McCline created HIVE-7537: ---------------------------------- Summary: Output vectorized GROUP BY with only primitive aggregate fields as columns so downstream operators will be vectorized Key: HIVE-7537 URL: https://issues.apache.org/jira/browse/HIVE-7537 Project: Hive Issue Type: Sub-task Reporter: Matt McCline Assignee: Matt McCline
When under Tez engine, see if the VectorGroupByOperator aggregrates are all primitive (e.g. sum) and batch the output rows into a VectorizedRowBatch. And, vectorize downstream operators. -- This message was sent by Atlassian JIRA (v6.2#6252)
