As feature flags move from simple toggles to core infrastructure, engineers face complex technical challenges that aren't covered in basic tutorials. This technical session dives deep into 3 critical problems in feature flag architecture at scale: maintaining consistency across regional deployments, handling circular dependencies between flags, and managing flag evaluation performance under heavy load.
The presentation walks through specific architectural patterns, including:
* Implementing consistent hashing for user targeting across distributed services * Using dependency graphs to detect and prevent circular feature flag references * Building efficient caching layers that handle rapid flag updates without sacrificing evaluation performance * Managing flag cleanup through automated detection of stale references
Each pattern will be demonstrated with code examples showing both naive implementations and production-ready solutions.
