Usage

$3

To make sure each message handled by pubsub creates a new process span, and propagates to any internal operation, do as follow:

`ts
import { pubsubPropagation } from '@opentelemetry/propagation-utils';
import { Span, propagation, trace, Context } from '@opentelemetry/api';

const patch = (message: Message[], rootSpan: Span) => {
const tracer = trace.getTracer('my-tracer');
pubsubPropagation.patchArrayForProcessSpans(messages, tracer);

pubsubPropagation.patchMessagesArrayToStartProcessSpans({
messages,
tracer,
parentSpan: rootSpan,
messageToSpanDetails: (message) => ({
attributes: { ... },
name: 'some-name',
parentContext: propagation.extract(....) as Context
}),
});
}
``
