Interested to hear what others are experiencing performance-wise with large volumes of data in Tableau:
What is the largest amount of data (how many rows) that you have extracted into Tableau, then used in a workbook?
Have you hit any performance issues on Tableau Server for users interacting with filters when you have a large amount of data?
Do you have any suggested guidelines for a max amount of data to use?
It's a lot less to do with row count but rather what you do with that data - want to show 100,000 points on a map - it's going to be slow. Desktop can handle 70m rows without blinking, but with complex table calcs will shudder after 10s of thousands.
As you're designing a dashboard, careful design and aggregation should be no problem.
