total # of zknodes

[Maarten Koopmans]

Hi,

I am mapping a filesystem to ZooKeeper, and use it for locking and mapping a 
filesystem namespace to a flat data object space (like S3). So assuming proper 
nesting and small ZooKeeper nodes (< 1KB), how many nodes could a cluster with 
a few GBs of memory per instance realistically hold totally?

Thanks, Maarten
