Export to Excel Funcitionality

Our system is hosted on Appian 16.2

We have a requirement to implement a report that would fetch and display ~30000 records from the database.
The source data set will have total 40 fields and user can select reporting fields to display in the grid using a checkbox.
They would also like to have the ability to export this data to excel.

Since user controls what fields to export, we were planning to use the Download Data Subset plugin.

Would it be feasible to download a large data subset(40 fields X 30000 records) using this plugin? Could we land into performance issues?

If yes, can any of you suggest a workaround to implement the export to excel functionality considering that a static base template cannot be used, as user controls what fields to export in the excel?
