---------------------------------
Summary: Remark the shuffle origin to ENSURE_REQUIREMENTS as far
as possible
Key: SPARK-35853
URL: https://issues.apache.org/jira/browse/SPARK-35853
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.2.0
Reporter: XiDuo You
In some queries, we might repartition by some column with a large partition
number manually to make parallelism big enough. However if the output
partitioning satisfies some other node (e.g. join/aggregate), this shuffle can
not be optimized by AQE due to the shuffle origin.
