Are the Zookeeper nodes created at Client Side or Server Side?
Hi,
I am newbee to Zookeeper. Sorry , If I am asking a silly and basic question.
I know that , when zookeeper client connects to the server and ask to
'create /test'. A zNode by name 'test' is created. Where is it created, at
client side or server side? What is the process to see it?
Thanks,
Raju.

A minor correction: The data is both stored in memory and written to a
transaction log, then snapshot to disk. There are tools for parsing the
transaction logs and snapshots but they're mostly useful only for server
debugging

The data is all stored in memory and then periodically snapshotted to disk
as far as I know. It will be under your data directory wherever you've
configured that to be, but it's not going to be human readable.

One question on this I have is, if I am running zookeeper locally on my
desktop, then where does the actual znode gets created? Can we see it in
some files at some location in Zookeeper directory path?

Server side.
You can use the zkCli.sh utility to see what's present on the server.
