While this is a viable work around, and a great way to access the entirety of your large report datasets, it seems like extra work to rebuild something that is already build in another module. Would Product consider adding the current "export to S3" piece to Report Builder? I think the current functionality would be helpful, but have additional suggestion:
- In Report preview - give the size of the total dataset (both physical size and # of rows) - this could guide users into which export method would work best for them.
