db shardning

Hi,

I have recently came to the point when I need to use more then one DB in my usecase.

I had to deal with storing and getting data from multiple DB, based on how old the data is.

I have an archive database to store all logs and data from models to which access will be occasionally.

My application has a customer and contract list, which one per year became obsolete, because of season ends.

Then I move those data to an archive db. However once a while I need to get those data.

Usecase:

DB shardnig would be a great use for me, to save models to DB based on season selected from list (I have a model for that).

If contract belongs to season 2010-2011, save to contracts_2010-2011, else save to contracts_2011-2012.

There is a large number of those contracts (and some of them will not be needed, in next year), therefore having those in one db (counting logs, payments, and django_admin actions and history) is a bad idea.

logs, actions and contracts could be stored in db, based on selection of season.

I hope this description would direct you on what I mean by this question.

Could MultiDB https://docs.djangoproject.com/en/dev/topics/db/multi-db/ an answer to my question?
