Spark & Databricks - Spark Architecture |Memory Management |Application Workflow (Theory) - Part 2

Welcome to DataToCrunch! 🚀 In this tutorial, we dive deep into Apache Spark's Architecture and its core components. Whether you're new to Spark or looking to strengthen your understanding, this video will guide you through Spark's inner workings, helping you grasp concepts critical for distributed data processing. What you'll learn in this video: ✅ An overview of Apache Spark's architecture ✅ Driver Node and Worker Node architecture in detail ✅ Memory management concepts: On-Heap vs Off-Heap Memory ✅ How garbage collection affects performance ✅ The complete Spark application workflow: From DAG creation to execution With structured explanations and visual aids, you'll gain a comprehensive understanding of how Spark processes large-scale data efficiently. By the end of this session, you'll be equipped to leverage Spark's architecture for scalable and optimized big data analytics.
