version Id after create

[Jun Rao <ju...@gmail.com>]

Hi,

It seems that the create API doesn't return Stat. So, the client can't
figure out the initial version id of a path after it's created. Should the
client just assume that the initial version is always 0?

Also, what's the difference between getVersion and getCVersion?

Thanks,

Jun

Hi Jun,

Yes, the initial version is zero.

There are 3 versions in the Stat structure.

- version The number of changes to the data of this znode.
- cversion The number of changes to the children of this znode.
- aversion The number of changes to the ACL of this znode.

The stat structure is documented here:

http://zookeeper.apache.org/doc/r3.1.2/zookeeperProgrammers.html#sc_zkStatStructure

Thanks!
