Logic Apps of type event hub listener process one message per instance

Question

Hi,

I am sending 100 messages every minute to an event hub. In my logic apps, I have a “when events available in Event Hub” trigger whose time interval is 1 minute. Instead of 1 execution every minute, I see 100 executions and each process 1 single message. Is that expected? Is that how Logic Apps scale scale?

Thanks,
Jianying

@Jianying Huang If you want to consume all the events on the same workflow instance then you need to disable the "Split On" property. Enable split-on to start an instance of the workflow per item in the selected array. Each instance can also have a distinct tracking id.
