u'll have documents, and then for each document a bunch of versions.

no idea, what this onupdate is expected to do here?
afaik these things are done with a mapper extension, but i'm not sure

what would be version field? something that counts the inserts for
that particular document_id?

yes, yourobj.document_id or whatever u named it as column.
