I've 2 separate questions regarding zookeeper: 1. Group Messaging: Is it possible to do group messaging with zookeeper 3.0.1 ? If not, are there any plans to add group messaging (say w/ casual ordering or even better total ordering) to future releases ? What would be the best approach if I need to do group messaging using zookeeper right now, should I use a separate group messaging or messaging broker service ?
2. What happens to Empheral Nodes when a zookeeper server (not client) dies or is separated from the group ? Supposing there are 5 zookeeper servers: server_1, ..., server_5 And a client c_1 connects to server_1 and creates an empheral node /nd_1 2a: What happens if server_1 dies/crashes (and c_1 is disconnected from server_1) ? Is /nd_1 automatically deleted ? 2b: What happens if server_1 is disconnected from the rest of the group (server_2 to server_5, but client c_1 still remains connected to server_1 ? Is /nd_1 automatically deleted ? What happens if server_1 regions the rest of the group ? what happens to /nd_1 then ? Thanks.
