Summary: Native Vector ReduceSink
Key: HIVE-12290
URL: https://issues.apache.org/jira/browse/HIVE-12290
Project: Hive
Issue Type: Improvement
Components: Hive
Reporter: Matt McCline
Assignee: Matt McCline
Priority: Critical
Currently, VectorReduceSinkOperator is a pass-thru to ReduceSinkOperator, so we
incur object inspector costs.
Native vectorization will not use object inspectors and allocate memory up
front that will be reused for each batch.
