BIG DATA load time
Hello friends.
I have the following situation:
I imported some .XML files into PowerQuery and transformed the data into the layout I need. I did this procedure with around a thousand files.
However, I have a folder with 70GB of .XML files that I need to import, transform and cross-reference with another table.
As you may have already noticed, this is a very high volume of files.
Yesterday I did a test with around 1 million files and after 10 hours of loading, the procedure still hadn't finished.
How can I work with this volume of data? I don't understand anything about MySQL or PostgreSQL.
Hi jeanrozin ,
Please try to filter and aggregate the data before loading it into Power Query, This will help you reduce the size of the dataset and improve performance.
