From Days to Seconds — Reducing Query Times on Large Geospatial Datasets by 99%
Summary
The Global Water Security Center reduced geospatial query times from days to seconds by implementing Databricks medallion architecture with H3 spatial indexing and autoloader data ingestion on 30-billion-row datasets. This achieved a 99% query time reduction, saving approximately $1 million annually in labor costs and enabling analysts to self-serve analysis workflows through automated notebook orchestration.
