High-performance SQL isn’t about clever queries—it’s about helping the optimizer minimize data movement. Use predicate pushdown, maintain table statistics, avoid Cartesian joins, and choose GROUP BY over heavy window functions when possible. For complex workloads, use materialization. The key to scalable data systems is writing SQL that’s efficient, predictable, and cost-aware.
