 You may use any file naming convention, however you must use all listed tokens. IoT Hub will write to an empty blob if there is no data to write.
 
-We recommend listing the blobs or files and then iterating over them, to ensure all blobs or files are read without making any assumptions of partition. The partition range could potentially change during a [Microsoft-initiated failover](iot-hub-ha-dr.md#microsoft-initiated-failover) or IoT Hub [manual failover](iot-hub-ha-dr.md#manual-failover).

When receiving telemetry messages from the built-in endpoint using either the event hub client or event processor host, you should [use the IoT hub connection string](iot-hub-devguide-messages-read-builtin.md#read-from-the-built-in-endpoint) to establish the connection. This ensures that your back-end applications continue to work without requiring manual intervention post failover.
