I use Tableau Desktop 2023.3 to create a dashboard with multiple charts; the data source is a plain text file containing over 100 million rows. The process of generating the necessary extract (Hyper file) completes successfully.
I have a free Tableau Public account, and the dashboard publishes without any issues.
I would like to understand what is happening or how Tableau works, because recently, the data from the text file (the original source) was loaded into a SQL Server 2022 table and aggregated so that it now contains just over 20 million records. I created the corresponding new extract (Hyper file), but when attempting to publish it to Tableau Public, I receive an error message stating that the extract exceeds the maximum limit of 15 million rows.

@Roberto Barranco technically, you should not have been able to publish the original dashboard to Tableau Public with a file size greater than 15 million rows of data, to begin with; regardless of data source type.
So, I'm not sure how that was accomplished, perhaps a fluke? Tableau Public has had that 15M row limitation for a very long time.
As we know, things change over the years and Tableau Public is no exception. It's possible that when it was originally published, the version when it was published somehow allowed it to happen. But now, with newer versioning, tighter controls are likely reinforcing the limitation better.
