> Priority: Major
> Time Spent: 40m
> Remaining Estimate: 0h
>
> Performance tests are flaky due to transient errors that happened during data
> processing (eg. SocketTimeoutException while connecting to DB). Currently
> exceptions that happen on Dataflow runner but are retried successfully, fail
> the test regardless of the final job state (giving a false-negative result).
> Possible solution for batch scenarios:
> We could "rethrow" exceptions that happened due to transient errors *only* if
> the job status is other than DONE.
> Possible solution for streaming scenarios:
> (don't know yet)
