> The failure message is kinda unreadable... I guess the problem is we do not wait enough time as the completion of the span can be executed concurrently with normal scan operation.
> And also I saw this in the test code
> {code}
>     // RawAsyncTableImpl never invokes the callback to `onScanMetricsCreated` -- bug?
> {code}
> This is not a bug as you need to manually enable scan metrics by calling Scan.setScanMetricsEnabled(true).
> Let me also fix this.
