Advanced indexing techniques and partitioning strategies for high-velocity transactional databases.
As systems scale towards a billion rows, standard indexing and query patterns begin to degrade. This deep dive explores the shift from monolithic database architectures to partitioned, horizontally scalable strategies.
Key areas explored include:
- Native Declarative Partitioning in PostgreSQL 12+.
- BRIN Indexing for massive datasets where traditional B-Trees become too large for memory.
- The role of Citus for distributed PostgreSQL workloads.
We provide benchmarks comparing sequential scans vs. partitioned lookups, demonstrating a 40x improvement in query latency for time-series data clusters.
