chore: migrate span meta/metrics to native storage by brettlangdon · Pull Request #17493 · DataDog/dd-trace-py

brettlangdon · 2026-04-13T14:46:58Z

Description

Migrate the new Span attribute API off of the Span Python class and into the SpanData native class.

This moves the storage of meta/metrics into the libdatadog Span stored on SpanData instead of in Python dictionaries.

We also move set_tag/set_metric to using _set_attribute directly since the _meta/_metrics attributes are now gone, this allows us to simplify the branch paths in set_tag a bunch.

Depends on:

Testing

Risks

Additional Notes

Notable performance changes:

✅ add-metrics
Time: ✅ 79.730ms (SLO: <93.500ms 📉 -14.7%) vs baseline: 📉 -10.7%
✅ add-tags
Time: ✅ 106.026ms (SLO: <155.000ms 📉 -31.6%) vs baseline: 📉 -22.6%

Flask/Django simple are showing about same-same as baseline.
