Hi
I have some queries which are as below:
1) I have daily orders files lying in one single folder in S3. Each day txn is a separate file. How do I see a consolidated data of all the individual transaction file.
2) I have kept modifying the transaction file in the past. So the column headers will differ. But certain key columns will always be there in the file. How do I see the key data once the problem number 1 is resolved and I have to analyse certain fields of the consolidated file (and files will have different number and arrangement of headers)
3) I want to understand if it can continuously update the file and analysis when we add files to the folder for future days.
The error I get when I modify the data is
