I'm actually working on a similar problem right now so I appreciate your comments. What if the data is already in the Python process so I don't have the ability of doing a `group by` at the database level? Should I perform this functionality in the Python code itself, or should I write to another database table and do the `group by` there? Edit: upon further reflection I think my application is at the tipping point where it needs another database table.
