Ingest OpenTelemetry metrics with Prometheus natively

The protobuf format supports native histograms. That’s the most straightforward way, if you have a client library for it. Go does, for instance.

OpenTelemetry is push, so if you need pull and no new daemons this PR doesn’t help you.

Yeah, I have been reading up a bit. Only it's not clear to me if the protobuf format and text format can be mixed?

Can one service A use text-format and service B use protobuf both scrapped by the same Prometheus sidecar?

Yes. Scraping is done over http, and the format is negotiated via the ‘accept:’ header.
