Create a filter that allows me to say 'Show the top N categories by value', e.g. 'Top 5 countries by sales'
Currently the only way to successfully develop against large data sets is hide them behind views. The within the view you use TOP N to limit the rows during development for speed. By comparison, Tableau has a feature that allows you to select ALL, TOP N or SAMPLE N when building the columnstore which is very useful.
