Full-Stack Database Optimization: Indexing Strategies, Caching Layers, and Query Performance Tuning
In high-throughput web applications, the database is almost universally the primary performance bottleneck. While compute layers can be scaled horizontally with ease, database contention, lock waiting, and unindexed queries can degrade user experience and inflate infrastructure costs. Engineering high-speed applications requires deliberate database optimization across multiple tiers. 1. Precision Indexing Strategies Indexes are essential for
