I was wondering if anyone knew the preferred upload file type is for CartoDB.I upload zipped .shp files for polygons, and sometimes .csv file for point data. I noticed that when I uploaded a zipped .shp file it hit the 50mb account limit even though the file only ended up being 9mb in cartodb when I upgraded accounts.
Is this becasue it is duplicating the table during processing? Is there a preferred file type for cartoDB? GeoJSON?
