Your API is fast… until your database isn’t. Everything works fine in development. Then data grows. Suddenly: • Queries slow down • APIs take seconds • CPU usage spikes I faced this while scaling a backend system. The issue wasn’t the code. 👉 It was missing indexes. Most developers: - Add indexes blindly - Or don’t add them at all Both are dangerous. In real systems: 👉 Every query must be designed with indexing in mind. What worked for me: • Identifying slow queries first • Adding indexes based on query patterns • Using compound indexes for real use cases • Avoiding over-indexing One small index reduced a query from seconds to milliseconds. That’s the difference indexing makes. I’ve broken down real examples and optimization strategies here below, How do you approach query optimization in your system?
