Replace string literals with constants for worker table column names #308
Description
This issue tracks the fix to address the code review comment in #226.
I know you said you didn't use constants because of code readability, but I don't like the potential risk of regression here by having these values be separate. So I'd strongly prefer that we make constants for each of these - even if it does decrease the readability of the query slightly.
