How to start trace with custom trace-id and parent-id?

Bắt đầu với các điểm vào Java được nêu trong ví dụ—GlobalTracer.get(), buildSpan(...).asChildOf() và CustomSpanContext—và so sánh cách các Kafka header đã lưu được sử dụng trong outbox container. Xác định API được hỗ trợ nào, nếu có, chấp nhận trace-id và parent-id trong khi vẫn duy trì distributed tracing. Hoàn tất khi một span từ publishFromOutbox xuất hiện trong trace hiện có cùng với các log tương quan.

Describe the feature you'd like

Hi,

We are storing outbox events for Kafka in the database with current span context headers:

headers={
x-datadog-parent-id=1425649086485655485,
x-datadog-sampling-priority=1,
tracestate=dd=s:1;
o:rum;
p:13c8ec4a6e566fbd,
x-datadog-origin=rum,
traceparent=00-000000000000000024fefac4c68ae928-13c8ec4a6e566fbd-01,
x-datadog-trace-id=2665843752501438760
}

and when these outbox events are picked (by a different container), we want to trace that operation but attach those spans to an already existing trace so that we can have support for:

• distributed tracing
• distributed logs

Describe alternatives you've considered

This is what we tried

  void publishFromOutbox(final Outbox outboxEvent) {
    final var tracer = GlobalTracer.get();
    final Span span = tracer.buildSpan(JOBS)
      .withTag(DDTags.RESOURCE_NAME, OUTBOX_SCHEDULER_PUBLISH)
      .ignoreActiveSpan()
      .asChildOf(new CustomSpanContext(
        outboxEvent.headers().get(X_DATADOG_TRACE_ID), outboxEvent.headers().get(X_DATADOG_PARENT_ID)))
      .start();
    tracer.activateSpan(span);
    publish(outboxEvent);
    tracer.activeSpan().finish();
  }

but we can see this doesn't work. Trace is not created or attached to any existing trace.

How can we accomplish starting trace with custom trace-id and parent-id? For PHP services we are using this handy method that you provide

    /**
     * Apply the distributed tracing information on the current and future spans. That API can be called if there is no
     * other currently active span.
     *
     * The distributed tracing context can be reset by calling 'set_distributed_tracing_context("0", "0")'
     *
     * @param string $traceId The unique integer (128-bit unsigned) ID of the trace containing this span
     * @param string $parentId The span integer ID of the parent span
     * @param string|null $origin The distributed tracing origin
     * @param array|string|null $propagated_tags If provided, propagated tags from the root span will be cleared and
     * replaced by the given tags and applied to existing spans
     * @return bool 'true' if the distributed tracing context was properly set, else 'false' if an error occurred
     */
    function set_distributed_tracing_context(
        string $traceId,
        string $parentId,
        ?string $origin = null,
        array|string|null $propagated_tags = null
    ): bool {}
