[GitHub] [iceberg] bryanck commented on pull request #5783: [WIP] Build: Update Spark to 3.3.1

bryanck commented on PR #5783:
URL: https://github.com/apache/iceberg/pull/5783#issuecomment-1271705171

   I thought I'd mention that I uncovered a performance regression related to join distribution in Spark 3.3.0 vs Spark 3.2.x that impacts DSv2 sources like Iceberg. It would be nice if we could get a fix into Spark 3.3.1, but if not, we can work around it in the Iceberg Spark runtime. (The Spark ticket is [here](https://issues.apache.org/jira/browse/SPARK-40703) if interested.)
