[2026] The COMPLETE Apache Spark 4.0 Hands-On Guide - Master PySpark, Spark SQL, Structured Streaming, and Optimization

What you'll learn

✓ Understand Spark Architecture and its components - Driver, Executors, Cluster Manager, and how they interact.
✓ Learn about Spark's lazy evaluation model, DAG execution, Catalyst optimizer, Stage and Task execution, and how to monitor Spark applications using the Spark UI
✓ Master PySpark DataFrames and Manipulation techniques including filtering, grouping, exploding arrays, window functions, and advanced aggregations.
✓ Perform joins (inner, left, broadcast, multi-key, anti), unions, and complex transformations such as pivoting, handling nested JSON data, & nested arrays,.
✓ Create Broadcast Variables, Accumulators & User Defined Functions (UDFs & Pandas UDFs).
✓ Execute SQL queries directly on files (CSV, JSON, PARQUET, DELTA & more) and understand all Spark save modes (append, overwrite, and partitioning by column).
✓ Learn how to register DataFrames as temporary views, and work confidently with Date & Time functions including Unix epoch conversions.
✓ Tune Spark performance using partitioning, repartition, coalesce, AQE, shuffle optimization and Salting.
✓ Understand Driver OOM and Executor OOM errors, how executor memory pool works.
✓ Gain insights into Spark Garbage Collection, storage levels like MEMORY_ONLY, DISK_ONLY, caching strategies.
✓ Explore the window operations in streaming data such as tumbling, sliding, and session.
✓ Spark Connect and Deployment modes (local, cluster, client), and how to choose the right one for your application.
✓ Pandas API on Spark and how to use vectorized UDFs for performance optimization.
✓ Delta Lake Optimizations including Z-ordering, data skipping, Liquid Clustering for faster queries.
✓ Build real-time pipelines using Structured Streaming with watermarking & exactly-once guarantees, along with Trigger Types and ForEachBatch operations.

Requirements

● Basic Python knowledge will be required.
● Basic SQL knowledge will be required.
● No prior knowledge in Apache Spark is required (Will cover everything from SCRATCH)

Description

This is a COMPLETE Apache Spark 4.0 Bootcamp you need in 2026 to become a PRO Spark Developer.
Whether you're a beginner or a working professional looking to upskill, this course will guide step by step with a hands-on, practical, and engaging lectures (doodle illustrations).
GAIN STRONG HANDS-ON WITH
• Spark Architecture & Components - Understand how Driver, Executors, and Cluster Manager work together behind the scenes. Learn DAG execution, lazy evaluation, Catalyst optimizer, stages, tasks & how to monitor everything using Spark UI.
• PySpark DataFrames & Manipulation - Master filtering, grouping, joins, window functions, exploding arrays, nested JSON handling, pivoting, advanced aggregations and complex transformations.
• SparkSQL - Run SQL queries directly on CSV, JSON, Parquet, Delta & more. Work with temp views, save modes, partitioning, date-time functions & Unix epoch conversions like a pro.
• Memory Management & Garbage Collection - Understand how executor memory pool works and why Driver/Executor OOM errors happen. Learn storage levels (MEMORY_ONLY, DISK_ONLY), caching strategies & Spark Garbage Collection in depth.
• Performance Tuning & Optimization - Learn partitioning, repartition, coalesce, AQE, broadcast joins, bucketing, shuffle optimization and Salting techniques to boost your Spark application's performance.
• Structured Streaming - Build real-time pipelines with watermarking & exactly-once guarantees. Implement tumbling, sliding & session windows along with triggers and ForEachBatch operations.
• Spark Connect & Deployment Modes - Understand Spark Connect and how it changes client-server communication. Learn local, client & cluster deployment modes and how to choose the right one for real-world projects.
