Thanks for pointing this out. I’ve updated the Spark concat implementation to add planner-level nullability inference using ReturnFieldArgs, marking the result nullable if any input is nullable, consistent with Spark SQL semantics. Runtime behavior is unchanged and all Spark tests pass. @kumarUjjawal @Jefffrey -- This is an automated message from the Apache Git Service.
