    Hi @Kunam, Umakanth , I understand that you're using Azure Event Hubs and you experienced the same event being delivered more than once.

    Azure Event Hubs is a big data streaming platform and event ingestion service. It has the following characteristics:

    • Low latency
    • Can receive and process millions of events per second
    • At least once delivery of an event

    If your process dictates processing an event exactly once, you need to build a checking mechanism, for example unique ID or something else to uniquely identify the event.
