What is Consumer Group in azure Event Hub?

Can anyone please figure out what is Consumer Group in Azure Event Hubs. And What is the use of it? I have surfed a lot of sites but I can't get a clear answer.

Solution

  • From the docs:

    Consumer groups: A view (state, position, or offset) of an entire event hub. Consumer groups enable consuming applications to each have a separate view of the event stream. They read the stream independently at their own pace and with their own offsets.

    According to this consumer groups are the way to logically separate your consumers, so they only see the events they are interested in.
