Good news: experimental OpenTelemetry tracing support has been added to the latest Google Cloud SDK! With a dependency bump and an environment variable set, tracing through the gcs driver would Just Work!

Tracing through the azure driver will be almost as easy to enable with the support built into the Azure SDK.

As for S3, otel tracing support exists... for AWS SDK v2. At least the work already put into this PR won't go to waste.

Note for anyone willing to continue this work: see #3701 (review) which is all still relevant.

I had a look into this. distribution depends on cloud.google.com/go/storage and the latest available tag for that package seems to be: v1.35.1

And it'd appear v1.35.1 still depends on cloud.google.com/go v0.110.8 which is one minor version behind what we'd like which is (v0.111.0).

Correct me if I'm wrong though, please.

@milosgajdos you are wrong. We can raise the version floor of a transitive dependency in our own go.mod if we want, because all Go modules are semver by decree.

[milosgajdos]

Ah, right.

Ooof I completely missed

distribution/go.mod

Line 38 in 60e7e87

cloud.google.com/go v0.110.0 // indirect

Closing as outdated but more importantly the basics have been put in place in #4188
