With respect to your 2nd question (in case it didn't get answered) nothing
happens to the ephemeral nodes. as long as the client is able to talk to any

One potential problem with solution 2 is that a naive implementation
may cause what we call a "herd effect": once there is a new message,
zookeeper generates a large number of notifications and all these
clients generate a request to receive the message. Depending on the

If I understand it correctly, you propose two mechanisms:
1- Have one single node, and modify the data of that znode;
2- Have a znode, say "/broadcast", and have clients creating a new
