How to write an asynchronous Histogram using the otel go packages?

[thediveo]

In an eBPF program I'm collecting information about certain Linux kernel tracepoint events into a map-based histogram. As these are high-count tracepoints it most probably doesn't make sense to do the histogram calculations in user space as this would require sending large numbers of events from kernel to user space.

After reading the OTel documentation, and https://opentelemetry.io/docs/specs/otel/metrics/api/#asynchronous-instrument-api and https://opentelemetry.io/docs/specs/otel/metrics/api/#histogram in particular, there doesn't seem to be an async version provided. It appears as if the assumption was that normally histograms only appear as aggregating other instrument measures, but not as "proxies" for already calculated histograms.

How do I implement an "async" histogram using the otel Go SDK?
