Optimize Spark Performance & Throughput

О курсе

In large-scale data engineering environments, performance issues such as slow transformations, excessive shuffle operations, and unbalanced workloads can impact analytics, reporting, and SLA commitments. This course teaches you how to analyze, diagnose, and optimize Apache Spark applications so they run faster, more efficiently, and more reliably. In this course, you’ll start by learning the fundamentals of Spark job execution, including how stages, tasks, shuffle operations, and execution plans reveal where bottlenecks occur. You’ll explore Spark’s built-in monitoring tools to interpret job behavior. From there, you’ll apply practical optimization techniques, including improving data partitioning, mitigating data skew, optimizing joins, configuring caching strategies, and choosing efficient file formats. You’ll also learn how to tune executors, memory, cores, and dynamic allocation to balance cost and performance across workloads. Learners should be familiar with basic knowledge of Python and Spark DataFrames; familiarity with JSON and SQL. This course is designed for data engineers and developers who need to diagnose and optimize Spark jobs running on large-scale distributed data pipelines. By the end, you’ll have the skills to confidently apply advanced tuning strategies, improve throughput, reduce shuffle overhead, and optimize resource usage.
