--------------------------------------------
Summary: Use percentage for join conversion size thresholds
Key: HIVE-20713
URL: https://issues.apache.org/jira/browse/HIVE-20713
Project: Hive
Issue Type: Improvement
Affects Versions: 4.0.0
Reporter: Prasanth Jayachandran
There are many places in join conversion that rely on absolute byte sizes for
join conversions (mapjoin, dynamic hashjoin etc.). When container sizes change,
these join conversion thresholds have to be tuned accordingly according to the
new container size. Instead, make the join conversions byte sizes a
percentage/fraction of container size.
