Azure Event hub outgoing messages throttling
Hi All,
We have been stress-testing the event hub lately and found a very interesting observation, the outgoing events of the service bus throttles to zero otugoing periodically whereas the incoming events are coming through consistently. I have only one event hub in the namespace with 16 parititions and 14 T.U.s configured.
The event hub serves a processing application which does some heavy processing on incoming events to transform them to a different stream, I have 16 instances of this application running (1 for each partition). Periodically, the AMQP subscription stops sending any new events on all the instances which is later picked up again. I have attached the metrics graph for reference.
Any help is much appreciated,
Thanks!
