---------------------------------
Summary: SortedIteratorMergerWithLimit could be slower when number
of total merge rows is small
Key: KYLIN-2483
URL: https://issues.apache.org/jira/browse/KYLIN-2483
Project: Kylin
Issue Type: Improvement
Reporter: hongbin ma
Assignee: hongbin ma
if the pushed down limit is small enough (say less than 100),
SortedIteratorMergerWithLimit will bring RELATIVELY significant costs. I'm
adding a new configuration entry called
kylin.query.merge-sort-partition-results.min-limit (default 100) to fix this
issue
