PySpark & Python: Hands-On Guide to Data Processing

Overview

This beginner-level course is designed to introduce learners to the powerful combination of Python and Apache Spark (PySpark) for distributed data processing and analysis. Through structured lessons and real-world examples, learners will recall foundational Python syntax, identify key elements of PySpark, and demonstrate the use of core Spark transformations and actions using Resilient Distributed Datasets (RDDs). As the course progresses, learners will apply advanced data handling techniques such as joins and data integration using JDBC with MySQL, and construct scalable data pipelines like word count using transformation chains. Each module emphasizes a blend of conceptual understanding and practical coding experience, enabling learners to analyze, debug, and evaluate their PySpark applications efficiently. By the end of the course, learners will have gained hands-on proficiency in building distributed data workflows and be prepared to advance toward more complex data engineering and big data analytics challenges.

Syllabus

Fundamentals of PySpark and Python

This module introduces learners to the foundational concepts required for working with PySpark, beginning with the evolution of data and the relevance of distributed computing frameworks. It establishes the basics of Python programming, emphasizing syntax, structures, and control flow needed for developing PySpark applications. By the end of this module, learners will be equipped with essential programming knowledge and a clear understanding of how to initiate PySpark-based data processing.

Advanced Data Handling and Joins in PySpark

This module builds on the foundational knowledge of PySpark by introducing learners to advanced operations including DataFrame manipulation, join operations, and external data integration with MySQL. Through hands-on examples, students will explore how to process, combine, and analyze distributed datasets effectively. The module culminates with practical application through the classic Word Count problem, reinforcing transformation pipelines and aggregation techniques in a distributed environment.
