Hello @Sangeetha Priya S ,
if you use the Azure Data Explorer database data connection, IoT Hub messages can be ingested.
This is done using the IoT Hub 'event-hub-compatible-endpoint'.
Although the IoT Hub is not a database, it can store incoming messages for up to 7 seven days:
This way, consuming resources like Azure Data Explorer can be halted for a certain time.
If messages are not picked up, the IoT Hub will forget them after the specific time span.
If your ADX is started again, all stored messages in the IoT Hub will be released.
Be aware this can produce a certain ingestion load on your cluster, based on the number of stored messages.
