BRIN Indexes for Large Partitioned Tables
Learn when Block Range Indexes outperform B-trees on huge, naturally ordered partitioned tables.
The Scale Problem
On tables with billions of rows, a B-tree index can grow huge and consume a lot of memory. BRIN (Block Range Index) offers a tiny alternative for naturally ordered data.
How BRIN Works
BRIN stores the min and max value per block range instead of one entry per row. A query checks which ranges could contain matching rows and scans only those blocks.
