Add support for "Transient" messages #52

Closed it-hms closed 10 months ago

it-hms commented 1 year ago

Please add the ability to toggle measurement data transmitted to Cumulocity as "Transient" though the addition of a header text in each message: X-Cumulocity-Processing-Mode: TRANSIENT This will allow for processing of data as it enters Cumulocity but prevent automatic storage of the measurement data

I see this in the HTTP documentation as an optional header. I'm not sure about the MQTT equivalent.

Adding detail:

MQTT equivalent involves changing the target topic(s). Typically, this just means instead of s/, we use t/, but in the case of aggregated data payloads, we simply append t/ at the beginning since it does not use s/ by default.
