Fetching 1,000,000 Rows in Minutes with PostgreSQL
Most people blame PostgreSQL when large queries are slow. In reality, performance at scale is about strategy.
Now follow me and learn!
1. Index the Filter Column
2.Use Cursor-Based Pagination (Not OFFSET)
3. Stream Results Instead of Loading Everything Into Memory
4. Select Only the Columns You Actually Need
5. Use Native Bulk Export (COPY) for Large Data Transfers
Just a tip on how you should fetch 1 million in minutes and less drama!
PostgreSQL isn’t slow.
Na Your design slow.
