Upgrade dd-trace-go v2

[xrn]

Is there a chance that datadog-lambda-go would upgrade dd-trace-go dependency to v2? https://github.com/DataDog/dd-trace-go/releases

Hi @xrn We're currently working on this and will update this issue once its upgraded!

@happynancee can you provide guidance on whether or not this package can be used with v2 of dd-trace-go? I've followed the migration instructions here but haven't been able to get things to work, and I suspect it's because the datadog-lambda-go package is not using v2.

Hi, we are actively working on this. Currently datadog-lambda-go doesn't support dd-trace-go v2. Please use dd-trace-go <= 1.73.1

@joeyzhao2018 do you have a target date for when this will be available? just so we can plan to make the upgrade on our side

Would also like to have the team look at this issue - the new tracer's internal telemetry code is posting incorrectly within AWS Lambda environments.

Hi @acoover, I have created the PR above. We'll be doing some testing in the following weeks. Although we don't have a specific date, we will try to get this merged and released before September.

Thanks @joeyzhao2018 for the update 👍 I wonder if this might help our issue at DataDog/dd-trace-go/issues/3808 - keen to try this out once released.

Would bumping to 1.74.0 help in the meantime? I migrated my codebase to v2 and now traces are broken in my lambda with this log:

2025/08/12 14:06:03 Datadog Tracer v1.73.0 WARN: Detected "v1.73.0" non-transitional version of dd-trace-go. This version is not compatible with v2 - please upgrade to v1.74.0 or later

[epot]

@joeyzhao2018 is the ETA you gave above still valid? we are a bit blind in our lambdas since we bumped our project golang dependencies to the tracer v2 library, so we are anxious to get this change :)

I noticed that the way to add v2 support is still actively being discussed. Is there anything I can do (like use an experimental release or whatever) to unblock us?

[jcarugati]

Is there something blocking this from being implemented ?

[joeyzhao2018]

For a transitional workaround, we released datadog-lambda-go v1.27.0 which uses dd-trace-go v1.74.6. You should be able to use dd-trace-go v2 along with this version.
