Hi Tim, >>>> (1) Using PurgeTxnLog a utility exposed by ZooKeeper. Administrator can run 'cronjob' on the Zookeeper server machine.

Probably you can visit this section for more understanding. http://zookeeper.apache.org/doc/trunk/zookeeperAdmin.html#Ongoing+Data+Directory+Cleanup You will be able to achieve the desired functionality using both the options. Anyway internally both are doing the cleanups using PurgeTxnLog utility. Only the difference is, (1) is a kind of external scheduling and (2) is automatic way. IMHO, you can go for automatic purging and admins not required to take effort on making cronjob.
