Ace your DP-600 certification exam with our detailed guide on using PySpark for time Series Analysis. Learn how to transform and visualize large datasets with Parallel Processing, minimize data duplication, and reduce load times.

Question

You have a Fabric tenant that contains JSON files in OneLake. The files have one billion items.

You plan to perform time series analysis of the items.

You need to transform the data, visualize the data to find insights, perform anomaly detection, and share the insights with other business users. The solution must meet the following requirements:

• Use parallel processing.
• Minimize the duplication of data.
• Minimize how long it takes to load the data.

What should you use to transform and visualize the data?

A. the PySpark library in a Fabric notebook
B. the pandas library in a Fabric notebook
C. a Microsoft Power BI report that uses core visuals

Answer

A. the PySpark library in a Fabric notebook

Explanation

PySpark is the Python library for Apache Spark, which is a powerful open-source data processing engine built around speed, ease of use, and sophisticated analytics. It supports parallel processing, which can significantly reduce the time it takes to load and process large datasets like the one billion items in your JSON files. PySpark also minimizes data duplication by using Resilient Distributed Datasets (RDDs), which are fault-tolerant collections of elements that can be processed in parallel.

While the pandas library is a powerful tool for data manipulation and analysis, it does not inherently support parallel processing. This could be a limitation when dealing with such a large dataset.

Microsoft Power BI is a business analytics tool that provides interactive visualizations and business intelligence capabilities. However, it is not designed to handle the transformation and processing of large datasets in the way that PySpark can.
