SQL Query Optimization: Cutting a 9M‑Row Scan from 17 s to 300 ms

The article analyzes why a MySQL LIMIT OFFSET query on a 9.5 million‑row table takes 16 seconds, demonstrates how moving the filter into a sub‑query that returns only primary‑key IDs and joining back reduces execution to 0.35 seconds, and validates the theory by measuring InnoDB buffer‑pool page accesses.
