OTEL Exporter endpoint unavailable makes worker itself unstable

[oskarm93]

I had an issue yesterday where the endpoint I used in the exporter configuration was slow or unavailable, throwing 503s.
During that time, P99 latency on my workers spiked to >15s without an obvious cause (because calls to the exporter aren't traced).

Is what I observed expected?

I checked the exporter code, and it uses a fetch call to send telemetry, but that means the worker cannot finish until that fetch call is completed?

otel-cf-workers/src/exporter.ts

Line 60 in effeb54

unwrap(fetch)(this.url, params)

This would impact latency and availability of the worker. I know you can schedule some calls to complete for after the worker returns to client, e.g. with waitUntil.
