We built our own tool using zookeeper. We need to manage clusters of nodes, clearly property files were not scalable enough to be of any help here.
All the configuration values are written using Clojure expressions, not just EDN like stuff, we do eval code loaded in the configuration to provide extensibility. We wrote a DSL to maintain the configuration. You can then implement versioning, rollbacks, .... whatever features you may need. When a node boots, it needs a 4 lines property file to find its root in the cluster configuration. Any process on the node pulls it's configuration from this root. This approach might be too heavy for your needs however. Luc P. > After suffer xml or properties configuration for long time, I'm looking for > a new configuration solution for Clojure or Java.
