I investigated the Spark 4.1 compatibility surface. A full Spark 4.1 profile looks significantly broader because it would also affect mixed-format Spark integration, Paimon, AMS embedded Spark usage, Scala 2.13/JDK 17 requirements, and the version-specific Spark modules. However I think there is a smaller first step that could address the Iceberg optimizer use case in this issue: - Add Spark 4.1 support specifically for `amoro-optimizer-spark` - Target Spark 4.1 / Scala 2.13 / JDK 17 - Keep the existing Spark 3.5 optimizer build unchanged - Limit support initially to native Iceberg optimization - Add a Spark 4.1 runtime smoke/integration test - Avoid enabling Spark 4.1 globally for mixed-format/Paimon modules I have already checked that the Spark-facing optimizer classes compile against Spark 4.1, but runtime compatibility still needs to be verified. If so, I'm happy to work on it on the pr. -- This is an automated message from the Apache Git Service.
