In the ever-evolving landscape of data engineering and analytics, proficiency in distributed computing frameworks is paramount. Apache Spark has emerged as a leading force, and this Udemy course, ‘Apache Spark 3 for Data Engineering & Analytics with Python,’ is an exceptional resource for anyone looking to harness its power.
This comprehensive course meticulously guides you through the intricacies of Spark architecture and execution concepts. You’ll gain a deep understanding of both the Structured API (DataFrames) and the RDD (Resilient Distributed Datasets) API, learning to perform a wide array of transformations and actions. From setting up your local PySpark environment to interpreting the Spark Web UI and DAGs for execution analysis, the course covers all the foundational elements.
The curriculum delves into practical applications, teaching you how to read and write various data formats, including semi-structured data like JSON and the efficient Parquet format. You’ll master data manipulation techniques such as creating new columns, filtering, handling duplicates, augmenting DataFrames, and performing complex aggregations with Spark SQL functions. The ability to create user-defined functions (UDFs) adds another layer of flexibility to your data processing toolkit.
A significant portion of the course is dedicated to Databricks, a cloud-based platform built around Spark. You’ll learn to create Databricks accounts, clusters, and notebooks, and leverage Spark SQL for database and table management, including DML, DQL, and DDL operations. The practical project work, involving sales data analysis and research data manipulation, solidifies your learning by applying these concepts to real-world scenarios. You’ll create visualizations using Seaborn and Matplotlib, answering critical business questions.
