What's needed?

The ReceiveComponentDataStream rpc returns a stream of responses each of which containing a list of metric_samples in the data. The only parameter that can be passed is the component_id which implies that the returned stream contains all metrics that are streamable by this components.

From a user perspective not all of these metrics are used and thus are ignored. Still the user has to iterate over the full list.

Proposed solution

Instead the users could provide a filter with only the metrics that they need.

message ReceiveSensorDataStreamRequest {
  // The sensor ID to subscribe to.
  uint64 sensor_id = 1;
  repeated metric filter 
}

Use cases

Creating high level objects in the SDK that stream composed data but aren't interested in the full data stream. Among the metrics that might not be of interest are all kinds of harmonics, (re)active energy, power factor, total harmonic distortion.
