Subject Re: Any practical limits to the number of znodes?

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.
