AWS Distribution for OpenTelemetry Collector (as configured by Dwolla)

Custom OpenTelemetry Collector distribution with AWS components and Dwolla-specific processors.

Why a Custom Build?

This distribution builds upon the AWS Distro for OpenTelemetry (ADOT) by adding:

1. Transform Processor - Enables efficient pattern replacement in span attributes (e.g., replacing ! with : in peer.service)
2. Link Extractor Processor - Custom processor that extracts linked trace IDs from OpenTelemetry span links and copies them to span attributes

The Link Extractor Problem

AWS X-Ray does not natively support OpenTelemetry's span links concept. When traces reference other traces via links, this relationship is lost when exported to X-Ray.

The linkextractor processor solves this by:

• Extracting trace IDs from span.links
• Copying them to a linked_trace_ids attribute on the span
• Making these relationships visible in X-Ray as indexed attributes

This allows Dwolla to maintain trace relationships and query for linked traces in X-Ray.
