In this episode of Database Tech with Fexingo, Lucas and Luna dig into a hidden performance trap in modern databases: JSON schema validation. When you store semi-structured data in columns like PostgreSQL's JSONB or MongoDB, every write triggers a schema check against your defined rules. Lucas breaks down the cost using a real-world example from a logistics company that hit 50-millisecond write latencies after adding a 15-field JSON schema. They discuss why the validation overhead scales with document complexity, not size, and how a simple change—moving validation to the application layer—cut their p99 write latency by 80 percent. Luna pushes back on whether that trade-off is always safe, and they explore where schema validation belongs in your data pipeline. If you're using JSON columns with constraints, this episode will change how you think about write performance. No fluff, just a deep, practical dive into a specific query-engine behavior that most teams discover the hard way. #DatabaseTechWithFexingo #TechPodcast #JSON #SchemaValidation #PostgreSQL #MongoDB #Performance #WriteLatency #DataEngineering #QueryOptimization #NoSQL #SQL #DatabasePerformance #BackendEngineering #SoftwareArchitecture #FexingoBusiness #BusinessPodcast #DataStorage Keep every episode free: buymeacoffee.com/fexingo
