what if the history data volume of parquet file is in TBs and there is an update event of 2-3 records of historical data. Does it make sense to purge entire set of parquet files and then repopulate it? Do we have any other efficient way to handle updates?

Replacing entire target parquet files after deleting will be very expensive.Basicaly its like truncate and reload every time

Do we really need to delete the parquet file?

Good video, nicely explained, one constructive feedback, too much use of the word "essentially"
