Hudson commented on ZOOKEEPER-496: ---------------------------------- Integrated in ZooKeeper-trunk #665 (See [http://hudson.zones.apache.org/hudson/job/ZooKeeper-trunk/665/]) > zookeeper-tree utility for export, import and incremental updates > ----------------------------------------------------------------- > > Key: ZOOKEEPER-496 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-496 > Project: Zookeeper > Issue Type: New Feature > Components: contrib > Environment: RHEL 4.6, libxml2 > Reporter: Anirban Roy > Assignee: Anirban Roy > Fix For: 3.3.0 > > Attachments: zktreeutil.patch, zktreeutil_2.patch > > Original Estimate: 168h > Remaining Estimate: 168h > > ========================================== > zktreeutil - Zookeeper Tree Data Utility > Author: Anirban Roy > Organization: Yahoo Inc. > ========================================== > zktreeutil program is intended to manage and manipulate zk-tree data quickly, > effi- > ciently and with ease. 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: The whole/partial ZK-tree is exported into a XML file. This helps in > capturing a current snapshot of the data for backup/analysis. For a subtree > export, one need to specify the path to the ZK-subtree with proper option. > IMPORT: 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. The import of subtree is also > possible by optionally providing the path to the ZK-subtree. > DIFF: 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 optional ignore > flag > from XML file. Diffing on a ZK-subtree achieved by providing path to > ZK-subtree with > diff command. > UPDATE: Make the incremental changes into the live ZK-tree from saved XML, > essentia- > lly after running the diff. > DUMP: Dumps the ZK-tree on the standard output device reading either from > live ZK > server or XML file. Like export, ZK-subtree can be dumped with optionaly > providing the path to the ZK-subtree, and till a certain depth of the > (sub)tree. > The exported ZK data into XML file can be shortened by only keeping the > static ZK > nodes which are required to prime a cluster. The dynamic zk nodes (created > on-the- > fly) can be ignored by setting a 'ignore' attribute at the root node of the > dynamic > subtree (see tests/zk_sample.xml), possibly deleting all inner ZK nodes under > that. > Once ignored, the whole subtree is ignored during DIFF, UPDATE and WRITE. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
