There was a problem hiding this comment.
I would love that, but as we discussed on our sync - we need a bigger decision if we want to follow this path.
If we do, we likely need some rough uncomplex inlined format explained that is not meant to be used for scraping and can be surfaced with promtool etc.

dismissed stale reviews from bwplotka and dashpole
this is a draft, changes incoming, also I made a mistake with the quantile values

This change is for demo purposes, exploring the benefits (and downsides) for the complex type format for OM2 captured in prometheus/docs#2679. This assumes Prometheus stores NS and NHCB (and NH) going forward (for best case efficiency), but is expected to work for classic mode too with little overhead (benchmarks will tell us). Part of the PromCon talk we do with @krajorama Signed-off-by: bwplotka <[email protected]>

Results are (expectedly) impressive: prometheus/prometheus#17293 One observation is that buckets are a bit dense (readability). However we don't have spaces in any other place (e.g. labels) |

It isn't hard to come up with a representation, based on previous work in https://github.com/prometheus/proposals/blob/main/proposals/2024-01-29_native_histograms_text_format.md .
