It's great that we're talking about tracing / OTEL (Open Telemetry) in the context of GraphQL. We've recently added OTEL support to WunderGraph, allowing our users to trace through the Gateway and their services. Some more info on our OSS implementation can be found here: https://docs.wundergraph.com/docs/guides/monitoring-and-obse...

In addition, we've deployed all the required infrastructure like an OTEL Collector and OTEL backend using Clickhouse to offer a managed end-to-end solution including dashboard for traces and a trace overview.
