Hi all, We are using ZooKeeper internally and ran into same issue where we wanted Quotas to impose hard restrictions. We needed this primarily to protect ZooKeeper server against rogue client applications that may cause Zk server to use up the allocated memory thus affecting other clients as well.
We've changed ZooKeeper's (version 3.3) code to impose hard restrictions. Currently it's in testing. Once we are happy with how it we are planning to push changes back so it will be available for others as well. One thing to note our implementation is not configurable whether to impose quota or just warn if quota exceeded, it always enforces quotas if set on a znode.

It would be nice to change the quotas to impose that. This shouldnt be a big change but again given the Multitxn patch it might be a litte more complicated. thanks mahadev On Wed, Apr 27, 2011 at 2:13 PM, Fournier, Camille F.
