dataflow - updateif --> true()

arkiboys 8,326 Reputation points

In dataflow I have source1, alter row, sink1
alter row setting is using : update if --> true()
This process is working fine.
Sink1 is .parquet file and on each load I can see that the lastmodified date column of this .parquet file has been updated.
I would like to find-out, whether the file is re-created or just updated.
How can I find out what is happening to the file? is it updated or is it re-created?

Thank you

    That is my question. How do I find out if the system is updating or re-creating the file?
