Data Architect | Section 4 – How Spark Optimizes Your Query | Catalyst Optimizer | Apache Spark

Catalyst Optimizer in Apache Spark – Deep Dive In this video, we take a complete deep dive into the Catalyst Optimizer in Apache Spark — the intelligent query optimization engine behind Spark SQL, DataFrames, and Datasets. If you’ve ever wondered: How Spark converts logical plans into physical plans How joins are optimized automatically What is Rule-Based Optimization (RBO) What is Cost-Based Optimization (CBO) How Adaptive Query Execution (AQE) works How Spark reduces shuffle and improves performance This session will give you architect-level clarity. What You’ll Learn ✔ Catalyst Optimizer Architecture ✔ Logical Plan vs Physical Plan ✔ Analyzer & Optimizer Phases ✔ Predicate Pushdown & Column Pruning ✔ Join Reordering & Broadcast Join ✔ Cost-Based Optimization (CBO) ✔ Adaptive Query Execution (AQE) ✔ Real-world PySpark examples ✔ Production-level performance insights Catalyst Optimizer in Apache Spark Spark SQL Query Optimization Spark Logical Plan vs Physical Plan Spark Analyzer and Optimizer Spark Rule-Based Optimization Spark Cost-Based Optimization Adaptive Query Execution Spark Spark Join Strategy Optimization Broadcast Hash Join Spark Spark Performance Tuning Techniques Spark Query Execution Flow Spark Execution Plan Explained
