Hi Weide, 1. The old consumer is still depending on the ZK no matter if you use ZK for offsets or not, since it depends on ZK for group manage anyways. In the new consumer (0.9) we have completely the ZK dependance.
2. Yes, it queries the broker for leader info. 3. You can use a single consumer for multiple topics, but a single consumer can only talk to a single broker; if your topic spans across multiple brokers you would also need multiple simple consumers.
