Premature Optimization and Functional Dependency Trade-Offs
Explore the risks of premature optimization and the practical trade-offs in breaking functional dependencies in PostgreSQL. Understand how to benchmark performance, rewrite SQL queries, and apply denormalization only when necessary to improve application speed while managing data quality through proper cache invalidation.

Premature optimization
The CSV-model anti-pattern database modeling makes it easy to fall into the trap of premature optimization. Only use denormalization techniques when you’ve made a strong case for needing them.
A strong case means we’ve benchmarked our application code against our real production data or a dataset that ...
