Creates a new Event Hub. When creating an Event Hub, you can specify the following properties. If a property is not specified, Event Hubs uses the default value for this property. See EventHubDescription Properties.

Properties

In addition to the properties listed as follows, you can specify additional properties that appear in the Event Hub description, but are ignored by the service.

You must specify the properties in the order given below. Any property that is specified out of order is interpreted as a user property. This property will appear twice in the Event Hub description: once with the value that is set by the user, and once with the default value that is used by Event Hubs.
