Fallback for failed exports

[adriangb]

Is there any way to configure the collector to write somewhere "safe" if the downstream service that I'm exporting to becomes unavailable? E.g. retry an export 5 times then write it to disk or object storage.

Or is there even a way I could write an exporter or processor to handle this?

This might be the place to start: https://github.com/open-telemetry/opentelemetry-collector/blob/main/exporter/exporterhelper/README.md

If your needs go beyond what that provides, you can definitely write your own processor or exporter to do these kinds of tasks.
