----------------------------
Summary: Make conflict attributes resolution more scalable
Key: SPARK-30433
URL: https://issues.apache.org/jira/browse/SPARK-30433
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0
Reporter: wuyi
Currently, ResolveReferences rule only resolves conflict attributes of one
single conflict plan pair in one iteration, which can be inefficient when
there're many conflicts. We could make it more scalable by doing resolution in
batch.
