Hi Jon, We do not have any limit on the number of znodes in Zookeeper. Its mainly limited by memory, since it keeps the whole namespace in memory.
Also the lock mechanism is a good use case for zookeeper. It is listed as one of the recipes for zookeeper. http://hadoop.apache.org/zookeeper/docs/r3.0.1/recipes.html#sc_recipes_Locks mahadev On 12/29/08 5:54 PM, "Jon Stefansson" <jonstef1...@gmail.com> wrote: > I am considering using ZooKeeper as a Lock mechanism in an application that > eventually could produce several hundred thousand znodes per day.

Is this a good use case for ZooKeeper?
