chore(writer): enable native writer by default #14952

VianneyRuhlmann · 2025-10-20T16:11:40Z

Description

Enables the native writer by default. The native writer can still be disabled through _DD_TRACE_WRITER_NATIVE.

Testing

All tests are run with the native writer. The native writer have also been enabled on some services internally for dogfooding purposes.

Risks

This changes the logic behind trace export and client-side stats computation (for customers who enabled it). We expect no change in behavior for trace exporting. Client-side stats behavior may show some differences as the current python implementation is not fully compliant with the client-side stats spec.
