Summary: Exchange SWO table/algorithm strategy
Key: HIVE-24357
URL: https://issues.apache.org/jira/browse/HIVE-24357
Project: Hive
Issue Type: Improvement
Reporter: Zoltan Haindrich
SWO right now runs like:
{code}
for every strategy s: for every table t: try s for t
{code}
this results in that an earlier startegy may create a more entangled operator
tree behind - in case its able to merge for a less prioritized table
it would probably make more sense to do:
{code}
for every table t: for every strategy s: try s for t
{code}
