How One Engineer Cut Database Load by 90 Percent with Read Replicas
from The Software Engineering Podcast with Fexingo: Code, Architecture, and Engineering Best Practices Hosted by Fexingo
In this episode of The Software Engineering Podcast, Lucas and Luna dive into a real-world case where a simple architectural change—adding read replicas—cut database load by 90 percent. They break down the decision-making process, the trade-offs, and the engineering mindset behind scaling reads without breaking the bank. Along the way, they discuss connection pooling, replication lag, and how to know when read replicas are the right tool versus when they're just a band-aid. If you've ever wondered how to scale a database without a forklift upgrade, this episode gives you a concrete playbook. Plus, the hosts share why they keep this show ad-free and how listener support makes that possible. #DatabaseScaling #ReadReplicas #PostgreSQL #PerformanceEngineering #TechPodcast #SoftwareEngineering #CloudArchitecture #BackendDevelopment #SystemDesign #ScalingReads #ReplicationLag #ConnectionPooling #DatabaseOptimization #FexingoBusiness #BusinessPodcast #Technology #EngineeringBestPractices #Infrastructure Keep every episode free: buymeacoffee.com/fexingo
