Module: Datadog::Tracing::OTelThreadContext

Defined in:
lib/datadog/tracing/otel_thread_context.rb,
ext/libdatadog_api/otel_thread_context.c

Overview

Publishes a per-thread OpenTelemetry context record into a thread-local slot, so an out-of-process reader (e.g. the eBPF profiler) can discover it.

See the "OTel Thread Context" OTEP: https://github.com/open-telemetry/opentelemetry-specification/blob/main/oteps/profiles/4947-thread-ctx.md

Native functions are implemented in ext/libdatadog_api/otel_thread_context.c
