 *Method 2*: In order to get the desired query performance on a massive 
dataset, we recommend creating a Top-N measure for the target column and 
pre-calculating it when building the index. Please add a measure in the model 
editing page as follows. Fill in the measure **Name** for example 
`TOTAL_AMOUNT`, select **Function** as **TOP_N**, select **Function Parameter** 
as **Top 100**, and finally select the target column from the dropdown list.
