Firstly: Thanks a lot for sharing the dev summit notes, they are greatly appreciated. Also thank you for a great PromCon!
In regards to prometheus remote write metadata propagation consensus, is there any plans/projects/collaborations that can be done to perhaps plan work on a protocol that might help others in the ecosystem offer the same benefits to Prometheus ecosystem projects that operate on a per write request basis (i.e. stateless processing of a write request)? I understand https://github.com/prometheus/prometheus/pull/6815 unblocks feature development on top of Prometheus for users with specific architectures, however it is a non-starter for a lot of other projects, especially for third party exporters to systems that are unowned by end users (i.e. writing a StackDriver remote write endpoint that targeted StackDriver, the community is unable to change the implementation of StackDriver itself to cache/statefully make metrics metadata available at ingestion time to StackDriver). Obviously I have a vested interest since as a remote write target, M3 has several stateless components before TSDB ingestion and flowing the entire metadata to a distributed set of DB nodes that own a different set of the metrics space from each other node this has implications on M3 itself of course too (i.e. it is non-trivial to map metric name -> DB node without some messy stateful cache sitting somewhere in the architecture which adds operational burdens to end users). I suppose what I'm asking is, are maintainers open to a community request that duplicates some of https://github.com/prometheus/prometheus/pull/6815 but sends just metric TYPE and UNIT per datapoint (which would need to be captured by the WAL if feature is enabled) to a backend so it can statefully be processed correctly without needing a sync of a global set of metadata to a backend? And if not, what are the plans here and how can we collaborate to make this data useful to other consumers in the Prometheus ecosystem.
