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.

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.

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.14 votes -
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!

Explain how to access the IoT Hub created by the sample Azure Digital Twins
I started using ADT with the samples provided, and the "occupancy-quickstart" project created an IoT Hub automatically. I can send events to it and redirect them to another location using endpoints, but I don't see the hub anywhere in our subscription, and as such, I cannot manage it. Also, it doesn't appear when I run the "az iot hub list" command in the Azure console.
So, how can we access that hub? Or maybe a best practice would be to create one hub beforehand and assign it to the root of the ADT space tree by hand?
Thanks for clarifying…25 votes -

Link arbitrary sensor data types to arbitrary data sub types/data unit types
Currently, if you'd add a new sensor, for instance a 'Gas' sensor, we'd like to provide the following types:
Type: Manufacturer
Data type: Gas
Data sub type: Delivery
Data unit type: CubicMeterGasHowever, the Data sub type has to be named 'DeliveryGas'. Even though we'd also like an Energy sensor with:
Type: Manufacturer
Data type: Energy
Data sub type: Delivery
Data unit type: KilowattHourEnergyNow we have to define two separate sub types. If this is by design, let us know :)

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.

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.
