Centralized Application Configuration with Spring and Apache ZooKeeper
summary
Dealer.com moves application config out of files into a ZooKeeper-backed service that stores JSON, encrypts passwords per environment, and requires an audit/approve step before staging. A web UI edits configs and bindings, apps fetch and auto-create beans at startup via enable-remote-config, registering DataSources and RPC proxies into Spring; startup resolves inherited values in parallel and falls back to a cached last-known-good config. No live reload yet; tags and per-datacenter Observer nodes support overrides.
