 Hello Guys,
 
 Do we have support for CouchDB with SQlAlchemy? Can't seem to find
 much information anywhere so I'm guessing not, just thought I would
 check.

The SQL in SQLAlchemy pretty much says it all. The whole way CouchDB and 
RDBMS operate differs in so many respects that a sensible abstraction for both 
of them makes no sense without it being leaky as the Deep Water Horizon oil 
well...

For example, views in couchdb have to be persistent to be effective, whereas 
the power of RDMBS is to be able to deal reasonably well with ad-hoc build 
queries. Transactions and normalization are other problematic topics...

There's a long term plan to allow plugins that would provide attribute 
instrumentation and Session persistence services to objects that are persisted 
by a non-SQL database.  Such a plugin would need to be written by a third party 
for each database backend and querying would also be an ad-hoc affair.   So 
there's a notion of it but nothing is happening on that front right now.



 
 Thanks,
 
 Robert

I guess at this point you'd need to drop 'SQL' from 'SQLAlchemy' ;-)
