A pure scala exporter

[christiankjaer]

Maybe it's a lot of work, but I would love to get rid of all the java stuff for small services that I deploy.

It would be cool to have a HTTP exporter implementation using Ember with generated types from the spec.

Is it too much work to maintain, or would it be within scope at some point?

Yes! This is one of our proposed Google Summer of Code projects and we've received a proposal to work on it from a candidate :) If anyone would like to help mentor this project, please let me know!

Btw, the plan is to use gRPC.

Here is an absolute minimal example that exports a single span.

We have a pure Scala OTLP HTTP exporter now:

1. sdk-exporter module
2. OTLP HTTP client
3. OTLP HTTP traces exporter

There is a doc: https://typelevel.org/otel4s/sdk/overview.html.

gRPC exporter is also supported since https://github.com/typelevel/otel4s/releases/tag/v0.10.0.
