The StorageImpl class and others use the EXCEPTION_HANDLER defined in the BaseService class when invoking runWithRetries.

The RetryParams and Clock can be set in the ServiceOptions and will be used when invoking runWithRetries, however the exception handler seems hardcoded.

Is that a definitive decision or would it be possible to have the exception handler also be passed through the options ?

Why

In order to be particularly resilient to transient errors it would be beneficial to be able to retry on a larger set of exceptions.
