I could not reproduce this duplication, but I have an assumption Updates are broken down into 2 separate Delete>Insert operations. The iceberg format does not enforce unique primary keys... Perhaps there could be an edge case where a record is inserted and in the next commit interval it is updated immediately after the previous snapshot is written, somehow leading the engine to miss the delete operation, leading to 2 consecutive inserts. Again, this is just an assumption. There are many moving parts. I couldn't reproduce this issue in my integration tests.. -- This is an automated message from the Apache Git Service.
