  1. How to retrieve filename and file path from the trigger and consume in Databricks Notebook dynamically
  2. If the same file is being modified with no change in name but in data then will this trigger work? If not what is the walkaround?
  3. In landing we are getting file placed in with same name. That is same file is being overwritten. If we use allow Overwrites option to True will autoloader only takes care of the modified data as an incremental way or all the files are reprocessed? How to process incremental ingestion using Autoloader when same file is being modified. #Autoloader
