Thank you for your pull request and welcome to our community. We could not parse the GitHub identity of the following contributors: Raunaq Morarka.
This is most likely caused by a git client misconfiguration; please make sure to:

1. check if your git client is configured with an email to sign commits git config --list | grep email
2. If not, set it up using git config --global user.email email@example.com
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails

Thanks for submitting this. We should also consider adding it to the QueryCompletedEvent so that event listener plugins can access it.

@martint I've added resource waiting time to QueryStatistics to make it accessible in QueryCompletedEvent

@martint Travis job seems to be stuck in queued state, is it possible to re-submit it ?
