[Django]-Is it possible to do asynchronous / parallel database query in a Django application?

This very recent blog entry seems to imply that it’s not built in to either the django or rails frameworks. I think it covers the issue well and is quite worth a read along with the comments.

I think I remember Cal Henderson mentioning this deficiency somewhere in his excellent speech http://www.youtube.com/watch?v=i6Fr65PFqfk

My naive guess is you might be able to hack something with separate python libraries but you would lose a lot of the ORM/template lazy evaluation stuff django gives to the point you might as well be using another stack. Then again if you are only optimizing a few views in a large django project it might be fine.

I had a similar problem and I solved it with javascript/ajax

Just load the template with basic markup and then do severl ajax requsts to execute the queries and load the data. You can even show loading animation. User will have a web 2.0 feel instead of just gloomy page loading. Ofcourse, this means several more HTTP requests per page, but it’s up to you to decide.

Here is how my example looks: http://artiox.lv/en/search?query=test&where_to_search=all (broken link)

Try Celery, there’s a bit of a overhead of having to run a ampq server, but it might do what you want. Not sure about concurrency of the DB tho. Also, if you want speed for your DB, I’d recommend MongoDB (but you’ll need django-nonrel for that).
