Send metric value on change

[DonDoff]

For our project we would like to send a high amount of periodic data using asynchronous gauges via OpenTelemetry.
However due to the amount of data we're sending, we're seeing a high cost in processing the data.

As a solution we would like to only send data when it has changed.
Doing this could be either using the opentelemetry-cpp library in our application, or via processors in the otel-collector.
Currently this seems not to be possible.

Do people here have a solution to this problem?
