Azure Digital Twins
Azure Digital Twins is a platform that provides organizations with the foundation they need to create the next generation of IoT solutions. With Azure Digital Twins, you can virtually replicate the physical world by modeling the relationships between people, places, and devices in a special intelligence graph. You can use predefined data schema that are aligned to a solution’s domain-specific needs and that can accelerate and simplify it’s creation. You can query data in the context of a space rather than from disparate sensors. And you can build solutions that scale and replicate across multiple tenants.
More details are available in the Azure Digital Twins documentation. If you have a technical issue, please open a post on the developer forums through Stack Overflow.

Making a graph viewer available in the Azure portal
To easily get a clear overview of the Digital Twins hierarchy of spaces, it would be great to add a (readonly) graph viewer for Digital Twins. A graph viewer has already been build and published to GitHub. Why not add this option to the Azure portal as the Digital Twins Explorer. (https://github.com/Azure/azure-digital-twins-graph-viewer)
Optionaly the explorer could be used to add, modify of delete spaces, devices or sensors in a non-readonly mode.15 votesThanks for the suggestion! Though this was for the previous version of Azure Digital Twins, this is still relevant with the latest version’s sample – the ADT Explorer. This is a great idea and we’d love to see more feedback on this, but we have not planned this yet

Add support for direct export to Time Series Insights
Please add support for providing parameters for a Time Series Insights instance to which the Digital Twin resource can export all of its historical device data.

Add paging support
Since a max node limit now exists on API GET calls, it would be helpful to have support for the ODATA $count feature.

Postman Collection for download
It save a lot of time if there was a downloadable Postman collection with the API calls already defined (as with Swagger). It is simple to export/import a collection and environments can be used to ensure that credentials are kept separate.
7 votesThis is a great idea! We’re working on a bunch of improvements to our documentation, and a Postman collection is in the works. In the meantime you can use our OpenAPI definition to get started quickly in Postman
Thanks!

Enhance the current space graph model of digital twin to define store to persist historical sensor data to Cosmos or HD Insight..
Current Space graph model of digital twin does not store historical information, such as sensor data. Model should have capability to define the store and attached to Sensor(s) and other model

Add previous state in Digital Twin Property Change Events
In the new public preview, change events can be routed to external compute. In this event, the updated values of Digital Twin properties are included. I think it would be valuable to also include the previous state. This would also be valuable for relationship changes, when an item moves through the graph it can be important to know where it came from.
5 votesThis is a great idea! We’ll update the item once it’s on the near term roadmap.
Keep the votes coming!

Integrate Elastic/AzureSearch to add full text index and searching functionality
It would be really helpful to be able to search for values within the content of the Digital Twins, e.g. searching in the names, properties, keys and attachments of the nodes within the Azure Twin tree.

PUT /management/api/v1.0/endpoints/{id}
Hello,
I am trying to replace an already existing endpoint to make it point to a different Events Hub instance. Checking the swagger documentation for my Digital Twins, I saw the PUT /endpoints/{id} which should do just that.
But, I am currently getting a surprising error:
{"error": {
"code": "400.600.000.000",
"message": "An eventhub endpoint with DeviceMessage eventType has already been created. Only one endpoint of this combination can be created."
}}
This is a similar body to the one that I am using:
{
"type": "EventHub",
"eventTypes": ["DeviceMessage"],
"connectionString": "Endpoint=sb://my-namespace.servicebus.windows.net/;SharedAccessKeyName=full-permissions;SharedAccessKey=someKey;EntityPath=my-entity",
"secondaryConnectionString": "Endpoint=sb://my-namespace.servicebus.windows.net/;SharedAccessKeyName=full-permissions;SharedAccessKey=someKey;EntityPath=my-instance",
"path": "my-instance"
}Is…

Chunked Blob Upload & Custom Storage Container
Would be nice to be able to upload blobs using chunked API that Azure Blob Storage already uses. Also, would be nice to be able to associate a Storage Container with Space, so that all the blobs in that Space hierarchy would be stored there. Thanks!

Does all data have to reside on Azure for Digital Twin - are API "pull" calls avaliable
We are looking to create a digital twin based on the key asset attributes after it has undergone post processing from a device and is on an enterprise system. Rather that extract all the data continuously “Push” we would like to perform a pull on the data as required so that it is performed in a method that can substantiate the Digital twin when it is called upon “Pull” rather than continuous?
