What I've done in the past for a highly scalable (across many teams of
users) is employed a resource-requester model. Where you have a generic
accessor wrapper that behaves like a transaction, but when you construct the
transaction you pass in the userId. Every resource record will reference a
table of who is allowed to access it and with which access level. So the
queried tables inside of the authTransaction will implicitly join across
that permission table.
This approach is great because its hard to screw up. The interface simply
won't let you request a resource without supplying who is requesting it. The
downside is that its an extra join for every query.
Though I employed this technique with mongoDB and had no speed problems
because I put the access list directly into each table. :)
Apologies if this hard to follow, I'm sitting at a camp fire tapping on my

specific issues that you're running into that seem like they could be
