Wow, this is great stuff. I'll have to spend some time trying it out.
My big question, though, is how to interact with this stored query

I went off on a different track where I would store a list of filter

OK, with Beaker, if you are caching things on a dynamically generated
key, such as a key constructed from arbitrary parameters, I strongly

Hi!
I have people_table:

sa.ForeignKey('streets.id'), nullable=False),

OK, thank you.
But one last thought: Is storing the query rather than the result
really the way?
I mean, after a couple dozen complex, expensive change operations, the
user could end up with only 4 records. It would be more efficient to
just store the indexes rather than redo all the queries

I am having trouble writing a sqlalchemy query which selects all rows
where a field equals the max for that field, eg
q =
session.query(Snapshot).filter(Snapshot.totalqty==func.max(Snapshot.totalqty))
When I try and get the results of the query, I get the error below.
How should I use
