I have an AWS Glue crawler that is set-up to crawl new folders only. I tried to see if deleting a partition would cause it to re-visit the corresponding S3 folder, and it doesn't. Is there a way I can force a re-visit of a folder, short of changing the crawler to crawl all folders?
If you just wish to 'notice' a deleted partition, you could run MSCK REPAIR TABLE tablename.
Not sure the best way to automate it (perhaps Lambda to Athena?).
