Hi, Could you please clarify expected behavior in the following case: 1. Client connects to zk and creates ephemeral nodes /n1 and /n2 (using session1). 2. Client dies. 3. Client connects with new session to zk before session1 expired. 4. Client checks if /n1 exists and waits till it dies. 5. Is it guaranteed that /n2 will also be dead at this point? Or /n2 could still be alive (waiting till zk server)?
In other words does zk invalidates ephemeral nodes for a session atomically or not? (If it is not atomic then during some short time client could see part of ephemeral nodes removed and part of them still present for expired session?) It is not clear from the documentation: "ZooKeeper also has the notion of ephemeral nodes. These znodes exists as long as the session that created the znode is active. When the session ends the znode is deleted. Because of this behavior ephemeral znodes are not allowed to have children." If this happens not atomically, what is the correct timeout client need to wait to ensure that all ephemeral nodes from its previous session are removed? (sessionTimeout which client sent in request when creating session? ) Thanks in advance, -Maksim
