Spark and Big Data Batch Processing for Beginners

Modern organizations generate massive volumes of data that traditional databases simply cannot handle. To make sense of this information, you need to understand how distributed computing works and how to process datasets at scale. This text-based course guides you through the foundational concepts of big data, explaining how to partition, process, and analyze large datasets efficiently. You will transition from a beginner to a confident practitioner, learning how to write optimized batch jobs and manage distributed data workflows. This course emphasizes modern best practices, including structured APIs, type-safe operations, and performance tuning strategies that keep your data pipelines running smoothly. What you'll learn: - Understand the core principles of distributed systems, cluster resources, and partition strategies - Configure Spark sessions and work with the structured DataFrame API for data manipulation - Build robust batch processing pipelines to clean, transform, and aggregate large datasets - Apply optimization techniques such as caching, broadcasting, and minimizing data shuffling - Read and write data across common big data storage formats, including Parquet and JSON - Implement modern data practices by structuring your batch code with clear type hints and modular design We begin with essential terminology, exploring the architectural differences between single-node and distributed computing. From there, you will progress through structured text-based lessons that cover data transformations, aggregation techniques, and practical optimization strategies. This course is designed for aspiring data engineers, data analysts, and software developers who are new to big data. No prior experience with distributed systems is required, though a basic understanding of programming concepts will help you get the most out of the material.
