Labels: pull-request-available (was: )
> Support BHJ to shuffle join fallback in AQE
> -------------------------------------------
>
> Key: SPARK-56065
> URL: https://issues.apache.org/jira/browse/SPARK-56065
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.1.1
> Reporter: Chao Sun
> Priority: Major
> Labels: pull-request-available
>
> Currently in AQE, the BHJ to shuffle join replanning only has limited
> coverage and in many cases a BHJ can still fail with errors such as
> {code:java}
> Cannot broadcast the table that is larger than <maxBroadcastTableBytes>:
> <dataSize> {code}
> In AQE, we can detect the failed broadcast query stage and dynamically
> generate a new plan and fallback to shuffle join.
