SparkSQL : RDD vs DataFrame vs Dataset Explained (2025 Edition)

Curious about SparkSQL and how RDDs, DataFrames, and Datasets compare? This video dives into:
What SparkSQL is and why it matters for structured data analytics (spark.apache.org, sparkbyexamples.com)
RDD (Resilient Distributed Dataset): low-level, unstructured, fault-tolerant collection; ideal for complex, custom transformations (analyticsvidhya.com)
DataFrame: a structured, columnar, table-like API optimized by Spark’s Catalyst engine (databricks.com)
Dataset: combines RDD control + DataFrame optimizations + compile-time type safety (Scala/Java only) (databricks.com)
Side-by-side comparison: schema, performance, optimization, language support & use cases (analyticsvidhya.com)
Real-world scenarios: choose RDD for low-level, DataFrame for SQL-like, Dataset for type-safe Java/Scala apps
🎯 Walk away with a crystal-clear understanding of when and why to use each Spark abstraction — perfect for data engineers, analysts, and anyone diving into big data with SparkSQL.
