:tada: I think this should be looked at by @codesome as the most qualified person. I'll have a detailed look ASAP, too, but if there is anything wrong with this,...

Good question. I guess for the least amount of surprise, there should be no visible change of behavior. I.e. if we only disable ingestion, we would still show histogram related...

Also, since "experimental" means that we do not have any stability guarantees, we might (need to) change the on-disk format of histograms further down the road. In that case, feature...

@Nexucis yes, you are right. The idea surely comes from those offering Prometheus as a service, as they use the code in a multi-tenant setup and don't want to restart...

What we have now is the absolute minimum: Gate the ingestion of histograms (and point out in the documentation, including tool tips etc., that histogram features are experimental and ingestion...

I had one more line of thought about this: * To scrape Native Histograms, Prometheus needs to content-negotiate the old protobuf format for now. * client_golang still supports that, even...

Bumped to P1 again, as we should really not merge before we have at least an informed decision to not gate protobuf scraping (or, what I think is more likely,...

Maybe we can now even close this? I will amend the autocomplete doc strings to mention that it is an experimental feature, and then I think we don't need to...

Closing for now, simply re-open if you disagree with my statement above.

Yeah, as said, that's probably the hardest nut to crack here… I'm not an expert for the PromQL test framework, but I would tend to not see the syntax of...
