Nice But I reached here for finding an answer -> what if job run multiple time a day - Date partition is same but as the job is running at append mode so for each date folder we get multiple files which are mostly duplicates. How to get 1 updated file only inside date folder all the time ( irrespective of this job run multiple time in a day )

This approach assumes that the source is sending incrementals. If it's a full file everyday, how do you identify the delta prior to load into spark warehouse
