    Apache Spark Architecture RDDs to AQE

    The difference between a Junior Data Engineer and a Senior Architect isn't just syntax—it's understanding the Physical Plan. In this episode, we explore the architecture of Apache Spark to answer the questions that come up in every high-level interview and every complex production issue: • "When should I use RDDs vs DataFrames?" • "How does Spark handle Skew Joins automatically?" • "What exactly is AQE doing behind the scenes?" We cover the complete timeline from the raw flexibility of RDDs to the intelligent optimization of Adaptive Query Execution (AQE). Tune in to upgrade your mental model of distributed computing. 👇 Join the conversation: What’s the hardest Spark optimization issue you've faced? Let me know!
