Use MongoDB?

[rrader]

Event schema can be different for different types of events or some additional fields can be required. PostgreSQL constrains us to use static model, and to change it we have to make migrations. Schemaless db will help to avoid it. + it will make possible to add custom fields for particular event.

On other hand, static schema prevents of making custom fields that are not used in template, because it's easier to write template when you know what fields you will have for sure.

Who have experience with django+mongo, please comment if it's good idea.

Discuss.
