Question 151/151

You're working with time series data in Snowflake, specifically website traffic data with timestamps and page views. You need to calculate the cumulative page views for each day. However, the data contains missing timestamps, and you want to fill those gaps with a default page view count of 0 before calculating the cumulative sum. Which of the following approaches, used in conjunction with a cumulative SUM aggregate function, is MOST efficient?

A. Use a stored procedure to iterate through the date range, inserting missing dates with a page view count of O before applying the cumulative SUM.

B. Create a separate table containing all dates in the range and LEFT JOIN it with the website traffic data, using COALESCE to fill missing page views with 0 before applying the cumulative SUM.

C. Use a recursive CTE (Common Table Expression) to generate the missing dates and then UNION ALL with the existing data, filling missing page views with 0 using NVL, prior to applying the cumulative SUM.

D. Use the 'GENERATE_SERIES' function (if available via UDF) to create a series of dates, LEFT JOIN with the website traffic data, and use COALESCE to fill missing page views with 0 before the cumulative SUM.

E. Use a LATERAL FLATTEN function to generate a list of dates, LEFT JOIN it with the website traffic data, and use ZEROIFNULL to fill missing page views with 0 before the cumulative SUM.

Correct Answer: B

Creating a separate date table and using a LEFT JOIN with COALESCE is the most efficient approach. Stored procedures (A) are generally slower for large datasets. Recursive CTEs (C) can be resource-intensive. Using UDFs or Lateral Flatten (D & E) may also increase complexity and overhead compared to a simple JOIN. The key is to leverage Snowflake's ability to handle joins efficiently.
