Description

There are a few possible improvements we could make to make debugging retried queries using the Web UI:

• The Web UI should age out queries + their retries together - e.g. there should not be a state where a retried query is tracked by the Web UI, but the original query attempt has already been aged out
• It would be nice if there was an easy way to view a retried query + the original query together - one way to do this would be to modify the runtime profile page of a query so that it includes tabs so users can quickly switch between the runtime profiles of the retried query and all prior query attempts - this has the benefit that it makes it even more obvious to the user that a query was retried
• Add a link from the original query page to the retired query page, so that users can easily find the profile of the retried query
