However, for simple queries on small tables, a dedicated RDBMS may still outperform due to lower overhead. These systems rely on a rigid schema, ACID-compliant transactions, and a structured storage layer designed for consistency.
Distributed processing across multiple nodes In-memory caching for iterative algorithms Cost-based optimization for query planning Compatibility with cluster managers like YARN and Kubernetes Use Cases and Practical Applications The choice between Spark SQL and traditional SQL often depends on the use case. If the priority is real-time transaction processing with strong consistency guarantees, traditional SQL is the clear choice.
