---------------------------------
Summary: Determine when dynamic runtime filtering should be
disabled
Key: HIVE-16154
URL: https://issues.apache.org/jira/browse/HIVE-16154
Project: Hive
Issue Type: Bug
Components: Query Planning
Reporter: Jason Dere
Assignee: Jason Dere
Currently dynamic min/max/bloom optimization is always enabled. However there
are times where it may not be beneficial, such as if the semijoin has a PK-FK
relation and there are no filters on the semijoin table. Try to devise a way to
do a cost/benefit calculation to see if there is enough benefit to adding the
runtime filter.
