> MERGE INTO/UPDATE/DELETE support join hint
> ------------------------------------------
>
> Key: SPARK-51519
> URL: https://issues.apache.org/jira/browse/SPARK-51519
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 4.1.0
> Reporter: Yuming Wang
> Priority: Major
> Attachments: Example.png, Oracle Merge into.png

>
> This feature request aims to enhance Spark SQL by adding support for join
> hints in MERGE INTO, UPDATE, and DELETE operations. Join hints can help
> optimize query execution by providing the Spark SQL engine with additional
> information about how to perform joins more efficiently. This improvement
> will allow users to specify join strategies (e.g., broadcast, shuffle)
> directly within these operations, leading to potentially significant
> performance gains in large-scale data processing scenarios.
