i did a benchmark a while back to see the effect of turning off the
disk. (it wasn't as big as you would think.) i had to modify the code.
there is an option to turn off the sync in the config that will get you
most of the performance you would get by turning off the disk entirely.

My own experiments in my own environment where ZK is being used purely for
coordination at a fairly low transaction rate (tens to hundreds of ops per
second, mostly status updates) made me feel that disk throughput would only
be detectable as an issue for pretty massively abused ZK applications.
Hi Ashwin,
We have seen people wanting to have something like ZooKeeper without the
reliability of permanent storage and are willing to work with loosened
guarantees of current Zookeeper. What you mention on log files is certainly
a valid use case.
It would be great to see how much throughput

Hi, I've been reading the docs and trying out some basic Zookeeper examples.
I have a few simple questions related to recovery.
It would be good to have questions like these on the Wiki/docs to avoid
noobs like me asking the same thing over and over.

Just start it and it will download a snapshot from the other servers.
