Question is related to https://social.msdn.microsoft.com/Forums/azure/en-US/0192e371-b596-45ba-be4c-64d6b1ca5d41/iot-hub-routing-messages-to-only-one-partition-of-event-hub?forum=azureiothub

Assume: I have 2 devices in my IoT hub. Using the iot hub routing feature, messages are send to event hub.

Question: Does the device id based partition is maintained when it reached event hub? Not talking about inbuilt event hub, but the one that is configured as a custom endpoint. Also, if you can point to the documentation link that explains about this, would be helpful.

    @Gopikrishnan Bahuleyan Pillai We can confirm that, when routing to Event Hub, the partition key stays deviceid.
    Regarding the documentation, We have informed docs team to update the documentation.

    To understand more about the partitions, please see Partition key and Partitions

    Do let us know if you have any further queries.
