Thanks guys for the time and discussion (learning a lot on the side). If I understand correctly, it looks metrics-promotion on read is the way to go due to simplicity, esp in regards to alter table not having to alter auto-promoted metrics properties. But in this approach we have to manually pass in sortOrder in all places of write, and I missed it in the new SparkTableUtil and Flink, which I can add. I am wondering (being a better code aside), for this particular change what's the use-case covered by passing SortOrder instead of the latest table's sorted column names , auto-promotion of sorted columns would work given just the current sorted names, or no? I agree SortOrder is less hacky, but just to check my understanding, thanks, ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
