> I propose and plan to develop a ZK-tree utility for managing cluster data (ZK
> tree) quickly and efficiently. The utility operates on free-form ZK-tree and
> hence can be used for any cluster managed by Zookeeper. Here are the basic
> functionalities -
> Export ZK-tree: The whole ZK-tree is exported into a XML file. This helps in
> capturing a current snapshot of the data for backup/analysis. In addition,
> the data can be dumped as tree-like text format which is easily readable.
> Import ZK-tree: The ZK-tree can be imported from XML into ZK cluster. This
> helps in priming the new ZK cluster with static configuration. The import can
> be non-intrusive by making only the additions in the existing data.
> Diff ZK-tree: Creates a diff between live ZK data vs data saved in XML file.
> Diff can ignore some ZK-tree branches (possibly dynamic data) on reading the
> flag from XML file.
> Update ZK-tree: Make the incremental changes into the live ZK-tree from saved
> XML, essentially after running the diff.
