Good for Karma: Configuration at Runtime
summary
Defines runtime configuration with concrete tools and demos: Archaius polling once per second provides type-safe DynamicProperty objects and callbacks to reconfigure thread pools or timeouts without restart, etcd key-value with TTL and long-poll stores service URLs for service discovery and supports 3–5 node clusters, and confd rewrites nginx when keys change, while Togglz gradual rollout with consistent hashing exposes a web UI to toggle features by user, IP or percent so rollouts and rollbacks happen immediately in production.
