I saw aws glue does not support binary type. But my situation is I have to do ETL job from mongodb which some of column's type is UUID by binary. is there any chance that i can change to useable type in glue?

Interesting video, thanks! I was under the impression that resolveChoice could only be used on the "ChoiceType" schema in AWS Glue? I've been using applyMapping to resolve this issue (which requires generating a mapping for all columns you wish to keep, not just the ones you want to change... tedious for frames with lots of columns!)
