I think Spark should explicitly block DELETE / UPDATE / MERGE on merge-engine = first-row tables. Allowing these operations violates first-row semantics and can lead to silent data correctness issues due to CoW rewrites producing L0 files that shadow valid records. Failing fast here would align Spark behavior with Flink and protect users from unexpected results. -- This is an automated message from the Apache Git Service.
