Database Performance Tuning for Scalable Apps
Database Performance Tuning for Scalable Apps Databases are the backbone of scalable apps. To keep performance steady as traffic grows, tuning must be practical and measurable. Start with observability: collect latency distributions, query counts, cache hit rate, and resource use such as CPU, memory, and disk I/O. A clear baseline helps you see if a change truly helps. Understanding bottlenecks is the first step. Common culprits include slow queries, missing or poor indexes, and operations that scan many rows. Lock contention, high I/O waits, and heavy joins can also bite. Use production or staging data to identify where users feel slower. ...
