The input for this example is clickstream data from an online retail store. The goal is to find all sessions where the user visited the checkout page within 10 minutes of visiting the home page. Because there is no way to know in advance how many rows might appear between the home page and the checkout page, the example cannot use a LAG or LEAD expression. Therefore, it uses the Filter argument.
