'While sampling data, no data was received from '1' partitions' Unable to access data from blob

Hello,

I am trying to implement ASA job on cloud and the complete pipeline is:

SimilatedTemperatureSensor on edge-> ASAjob on edge -> blob storage container (Access Tier Hot) on cloud-> ASA job on cloud -> blob storage (Access Tier cool) on cloud

I can see the data in a first blob storage container file (It means data from simulated module to first blob is transmitting correctly), but second ASA job unable to access it.

I cannot access the data from blob storage to ASA job on cloud. Am I missing any configuration here?
Any suggestion would be great, Thanks.

Hello @ankita m ,

can you share the path within the blob storage container? Can you also share the path as registered in the ASA blob stream input?

While testing the input (eg, for five minutes) are you sure new blob files were arriving?

Notice the date/time-related path within the container, as seen in the documentation.

Hello @Sander van de Velde | MVP ,

The blob storage container path:

I have not set any path for ASA blob stream input

Is EventHub works better for ASA input than Blob storage?

Thanks.

Hello @ankita m ,

with blob storage container path, I mean the sub folder structure within the blob storage container. Like:

You have to find a match between the blob container folder structure and the ASA settings.

I'm not sure why you have the blob storage in between...

Your data is coming from an ASA job on the edge. So sending the messages to the IoT Hub is the normal step. From there, the message can be picked up by the ASA job in the cloud.

Yes, connecting to an EventHub (eg. using the IoT Hub routing capabilities) or an IoT Hub (because it exposes an eventhub-compatible-endpoint) is easier.

Thank you for the details,

I have blob storage in between because output of ASA job on edge supports only following options,

I have edge modules as:

FROM /messages/modules/SimulatedTemperatureSensor/* INTO BrokeredEndpoint("/modules/DataStream/inputs/temperature")

FROM /messages/modules/DataStream/* INTO $upstream

ASA job on edge is:

SELECT
*
INTO
temperature1
FROM
temperature TIMESTAMP BY timeCreated
WHERE ambient.humidity > 23

How can I send data from ASA edge job to IoT Hub?

Check the types of outputs for an ASA edge job:

If you select edgeHub, the output messages are available to route to either other modules or $upstream (to the IoTHub).

I see:

FROM /messages/modules/DataStream/* INTO $upstream

So, just fix your edge ASA job, the route is already there.
