[omaha] best python web framwork

[James Harr]

I share this sentiment about Zope.

On the other hand (and slightly OT), ZODB is a pretty interesting
database for light use.
- Pretty good at repeat reads.
- Terrible at writes (you'll only get about 60-80TPS on a standard
system, no matter how many threads you run).
- Super light weight modeling. With a 1 line decoration, and object
can now be shoved in ZODB.
- Transactions are serializable and it has a really cool way to
resolve conflicts without completely retrying a transaction. This is
optional, and is more interesting than it is useful.
- Handles cyclical object graphs
- Really easy to mess up transactions if you use threading. Get a DB
connection per thread and never share objects between threads (I
learned this the hard way -- oops).
- A year ago, docs were kind of sparse, but they've improved since then.
- You can basically think of it as a fancy "pickle these objects to
disk". There's no way to do aggregate queries without maintaining your
own indices/structures.

I've never used it for a full application because it seemed like a
risky time investment, but it might come in handy some day and is
worth toying with if you're bored. I ended up using
http://www.sqlalchemy.org/ for that project and love it. A lot of
frameworks give you a choice as to which model framework you use and
this is a good one.
