Every znode in ZooKeeper's namespace has a stat structure associated with it, which is analogous to the stat structure of files in a Unix/Linux filesystem. The fields in the stat structure of a znode are shown as follows with their respective meanings:
cZxid: This is the transaction ID of the change that caused this znode to be created.mZxid: This is the transaction ID of the change that last modified this znode.pZxid: This is the transaction ID for a znode change that pertains to adding or removing children.ctime: This denotes the creation time of a znode in milliseconds from epoch.mtime: This denotes the last modification time of a znode in milliseconds from epoch.dataVersion: This denotes the number of changes made to the data of this znode.cversion: This denotes the number of changes made to the children of this znode.aclVersion: This denotes the number of changes made to the ACL of this znode.
