Leveraging Feature Toggles for your Microservices
summary
Shows how to add FF4J to a Spring Boot app to get runtime feature flags plus config and usage metrics in minutes, using a Consul key-value store for shared flag state and Cassandra audit logging for monitoring. Demonstrates automatic flag creation when a service queries a missing flag, web UI and lightweight starter (no UI in every service), AOP/annotation-based flipping, CLI/REST endpoints, caching to avoid DB overhead, and targeted rollout strategies (by region, time, or user).
