Elephant in the Room, Episode 2: Working with Feature Flags, Read Replicas, and Postgres Analytics

Welcome to Elephant in the Room – presented by Aiven, the live series where we explore the real-world challenges developers face when working with PostgreSQL, the database that everyone depends on but few fully leverage.
In Episode 2, Jay Miller, Staff Product Advocate at Aiven, is joined by Alexis Roberson, Senior Developer Educator and feature flag enthusiast, to break down how feature flags help teams ship faster, reduce risk and improve user experiences in PostgreSQL-backed applications.

What we’ll cover

• How feature flags fit into modern PostgreSQL-backed architectures
• Strategies for storing, evaluating and managing feature flags with Postgres
• Using read replicas and analytics safely alongside application workloads
• Techniques for rolling out features without destabilising production
