Is it possible to add attributes to "instrumentation scope"?

[tigrannajaryan]

This OTEP proposed to add attributes to instrumentation scope.

This issue is a question for the maintainers of this repo: are we able to do this in a non-breaking manner and without significant performance impact?

I think that it's likely possible, yes - if I understand that OTEP correctly, the attributes would be added to the instrumentation scope when obtaining a tracer. Since that happens infrequently, I suspect it will not be a huge problem.

However, if any other @open-telemetry/ruby-approvers or @open-telemetry/ruby-maintainers want to chime in, that would be excellent.

We would need to add an optional parameter to the API here:

opentelemetry-ruby/api/lib/opentelemetry/trace/tracer_provider.rb

Line 17 in 113e513

def tracer(name = nil, version = nil)

and to the SDK here:

opentelemetry-ruby/sdk/lib/opentelemetry/sdk/trace/tracer_provider.rb

Line 51 in 113e513

def tracer(name = nil, version = nil)

The SDK Tracer initializer is marked API-private, so any changes there are backwards compatible. We will need to add the attributes to Scope (which is still InstrumentationLibrary for us), but that will be backwards compatible as well.

Thank you @ahayworth @fbogsany
I will close this, since all I needed for now was a confirmation.
