Aggregate Query Optimization: Overview

Optimize GROUP BY queries from minutes to seconds with proper indexing

Use covering indexes to eliminate table lookups in aggregations

Apply WHERE filtering before GROUP BY to reduce data volume

Leverage partial aggregation and incremental computation strategies

Implement materialized views for expensive recurring aggregates

Choose between DISTINCT, GROUP BY, and window functions for performance
