Have the option with streaming views to only send updated values to the target
In PI Integrator for Business Analytics 2020 Patch 1 (188.8.131.526) streaming views has the option to send messages when any selected key values are updated, but this publishes the complete message to the target, including attributes which have not updated.
It should be possible with the "any" message trigger to only send the updated values to the publish target. This option to only send updated data could be listed as one of the Value Options when configuring the message content.
