Javadoc

Create a Epoch based EventHub receiver with given partition id and start receiving from the beginning of the partition stream. The receiver is created for a specific EventHub Partition from the specific consumer group.

It is important to pay attention to the following when creating epoch based receiver:

Ownership enforcement - Once you created an epoch based receiver, you cannot create a non-epoch receiver to the same consumerGroup-Partition combo until all receivers to the combo are closed.
Ownership stealing - If a receiver with higher epoch value is created for a consumerGroup-Partition combo, any older epoch receiver to that combo will be force closed.
Any receiver closed due to lost of ownership to a consumerGroup-Partition combo will get ReceiverDisconnectedException for all operations from that receiver.
