Just wondering if you played with the hStore column in the postgres ways/nodes tables before diving into ArangoDB?
I see hStore as nosql-on-demand within a relational schema:

Nope we didn't, as I said in the post, it was one of the things we decided up front to use ArangoDB.
It is developed locally and we wanted to try if it scales up and assists us, or if we should go the "traditional" Postgres way that everybody else goes.
