Cloud-to-Cloud Interoperability multiple property types

Hi,

I'm working on setting up a connection between AWS an SAP Leonardo IoT, and currently in the documentation it says that,

"Currently, you can assign only one property set type of measured values for a thing type."

Do you now when multiple property sets will be available, or know a workaround for doing this?

The problem is that I have a device which is sending data with different frequencies, this means that the device shadow on AWS will be updated on different times with different data. I can't figure out how this will be handled in SAP Leonardo IoT?

Br,

Kasper

    Hi Kasper,

    Currently, Cloud-to-cloud interoperability ingestion only supports single timeseries PST with name based mapping. The support for multiple-psts is in the roadmap for cloud-to-cloud interoperability.

    A possible work-around would to be create a Property Set Type with all properties that will be sent at various point in time to the device-shadow. Also in AWS IoT Core, a given device has one shadow with properties that can be updated at different time instants

    You can use Snapshot API to read last non-null values for all properties with their corresponding ingestion time (thus returning the latest device-shadow state as in AWS). One disadvantage with this approach is that we’ll have null values for the other properties at that given time when querying using Thing Timeseries API. Hope this helps.
