How to link distributed tracing through x-datadog-trace-id and x-datadog-parent-id?

[gabrielleandro0801]

Hi,

I'm using sqs-consumer-v3 to consume a queue on AWS, not inside a Lambda function, but on AWS EKS.
Datadog attributes are coming on the message attributes as x-datadog-trace-id and x-datadog-parent-id. but I don't know how to link this parent span to the span I'm creating when I'm processing the message.

My code looks like this one

import { MessageAttributeValue, SQSClient } from "@aws-sdk/client-sqs";
import ddTrace, { Span, TraceOptions, Tracer } from "dd-trace";
import { Consumer, Message } from "sqs-consumer-v3";

const tracer = ddTrace.init({
  plugins: true,
  logInjection: true,
  service: "my_service",
});

const queue: string = "";
const handler = (message: Message) => {
// Do something with the message here
}

Consumer.create({
  attributeNames: ["All"],
  handleMessage: async (message: Message): Promise<void> => {
    try {
     const traceId = ""; // Extracted from Message Attributes
     const parentId = ""; // Extracted from Message Attributes

      tracer.trace(
        "my_service",
       {
         resource: "my_resource",
         service: "my_service"
       },
       async () => await handler(message));
    } catch (error) {
      console.log(error.message);

      throw error;
    }
  },
  messageAttributeNames: ["All"],
  queueUrl: queue,
  sqs: new SQSClient(),
});

So, how can I use these two variables traceId and parentId to link both spans?

Thanks in advance!
