PostgreSQL BRIN Indexes: When & How to Use Block Range Indexes

📰 Medium · Programming

Learn how to use PostgreSQL BRIN indexes to reduce storage space while maintaining query performance for time-series and append-only workloads

intermediate Published 18 Apr 2026
Action Steps
  1. Create a sample table with time-series or append-only data to test BRIN indexes
  2. Run the command `CREATE INDEX ON table_name USING BRIN (column_name)` to create a BRIN index
  3. Compare the storage space used by the BRIN index versus a traditional B-tree index using `pg_relation_size`
  4. Test query performance using range scans with the BRIN index and compare to traditional indexing methods
  5. Evaluate the physical correlation requirement for your data to determine if BRIN indexes are suitable
Who Needs to Know This

Database administrators and developers can benefit from using BRIN indexes to optimize storage and improve query performance, especially for large tables with specific physical properties

Key Insight

💡 BRIN indexes can significantly reduce storage space while maintaining query performance, but require a specific physical property of the data to be effective
