feat: make instrumentors optional dependencies (#2803) - #4424
Conversation
📝 WalkthroughWalkthroughThe SDK now declares instrumentation packages as optional dependencies. Instrumentor initializers log package-specific warnings when optional integrations are not installed. ChangesOptional instrumentation support
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new optional-installation behavior currently gives SageMaker users an incorrect package extra and provides inaccurate, sometimes silent, SQLAlchemy guidance, which can leave expected instrumentation unavailable or make setup failures difficult to diagnose. Merge should wait for these messages to be corrected or for the owners to explicitly accept the bounded risk. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

tracing setup to recommend the `traceloop-sdk[sagemaker]` extra instead of the
Bedrock extra, preserving the existing warning behavior.
- Around line 996-997: Update the ModuleNotFoundError handling in the SQLAlchemy
tracing setup to warn users to install the separate SQLAlchemy package, rather
than the undeclared traceloop-sdk[pymysql] extra. Ensure the failed dependency
check emits the warning instead of returning silently, while preserving the
existing tracing behavior when the dependency is available.

Correct the SQLAlchemy dependency guidance.
traceloop-sdk[pymysql] is not declared. opentelemetry-instrumentation-sqlalchemy is already a base dependency. Direct users need the separate SQLAlchemy package, and the current package check returns silently when it is missing. Update the message and warn when that check fails.

Use the SageMaker extra in the SageMaker warning.
Change the warning to recommend traceloop-sdk[sagemaker]. The current bedrock extra does not install opentelemetry-instrumentation-sagemaker.

Description
This PR optimizes the SDK by extracting all 30+ OpenTelemetry instrumentors from the core
[project.dependencies]inpyproject.tomlinto individual groups in[project.optional-dependencies].Users can now granularly install what they need (e.g.,
pip install traceloop-sdk[openai]). I also added anallextra sopip install traceloop-sdk[all]restores the previous behavior.In
tracing.py, the dynamic loader logic was updated to explicitly catchModuleNotFoundError. If an instrumentor is missing, it now logs a helpfulWARNINGrather than throwing anERROR.testdependencies group)feat(instrumentation): ...orfix(instrumentation): ....Summary by CodeRabbit
