----------------------------------
Summary: More general skew Join pattern matching
Key: SPARK-32201
URL: https://issues.apache.org/jira/browse/SPARK-32201
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0, 3.1.0
Reporter: Lantao Jin
Current the AQE skew join handling logic is very specified.
It can only handle the pattern like this:
{code}
SMJ
Sort
Shuffle
Sort
Shuffle
{code}
We propose a more general skew Join pattern matching approach.
In this patch, we can handle 3-tablesjoin, join with aggregation, and so on.
