From 	赵天烁 <zh...@meizu.com>

you can try to add a filter on a colum of some big fact table,before you try to pick some colum value as filter, tableau will send a select * query without any limit clause to list all the column value for you to choose from.and that is where it cause this problem.

forgot to mention that we do have some dimension table with 10x million records,add a filter on that will also cause the same issue
