If not I would expect it to live in the exporter helper instead of its own config package.

I was following configretry, which appears to be exporterhelper-specific but resides in /config. For one thing, I would like to be able to experiment with completely replacing exporterhelper. I should be able to replace exporterhelper w/ exporterhelper2 and re-use its configuration.

Say you're sure, and I'll move it to /exporter/exporterhelper!

I am not sure. configretry is a good example of this type of functionality existing in its own package.

The "config" package is a more generic, why would I experiment in a more generic package than in a more specific. You are incorrect about configretry, we use that in few other places in contrib, and that was the reason to "promote" it to a generic config, and not for experimentation.

@jmacd the configuration in TimeoutConfig is used in both exporters and receivers in contrib, can the first step to make it more usable generally be to move the existing functionality into configtimeout and then add the new setting? The first step would allow the packages that depend on it to move to using configtimeout

then the follow up PR can be to add short_timeout_policy

[jmacd]

If a processor -- say batch processor -- wants to respect timeouts, won't it need a configuration? I will submit an RFC.
