Summary: Vector processing in coprocessor
Key: KYLIN-1167
URL: https://issues.apache.org/jira/browse/KYLIN-1167
Project: Kylin
Issue Type: Bug
Reporter: liyang
Assignee: Dong Li
Some use has experience slow HBase processing when the scan range is over 20+
million records.
To improve coprocessor, one way is to process records in vector (instead of one
by one). Previous works by Power Drill (Google) and Tungsten (Spark) all
mentioned this technique. Said it can improve processing speed by 4 times or so.
