That makes sense,
Thanks,

The hybrid attribute is a Python function that invokes when it's called. So
it doesn't make sense for it to be a column property since there is no
attribute to be populated. Undeferred also doesn't make any sense because
the hybrid already calls a local in-Python function when accessed at the
instance level, not a database call.
A traditional column_property() can be deferred or undeterred, and when
called at the instance level will emit SQL to the database.
If you have an attribute that should only populate via SQL, then you need to
just use a column_property().

I suppose what I'm really after is a column_property (for class level) and
plain descriptor (for instance level), which is exactly what Hybrid
attributes are meant to be, but I wanted them to be part of the mapper and
undeferred in some cases.

I notice that Hybrid Attributes don't show up as mapper properties (since
they are class wide instead of mapper specific, I suppose). I couldn't
find documentation on whether I can undefer these? Or can I create a
synonym or column_property from a hybrid attribute in the mapper?
