YOUR DATABASE DOESN’T READ EVERY ROW. 📖
This is a dev post classified by Jev as Databases (a tutorial), kept by the Dev Radar because it carries real work, not commentary.
YOUR DATABASE DOESN’T READ EVERY ROW. 📖 Imagine 10,000 users. You need to find user 7,731. Without an index: 10,000 rows → search → search → search → finally found With an index: Index → jump → lookup → done That’s the whole idea. A database index exists so your query doesn’t have to scan everything. Less searching. Faster queries. Same data.
