Funny I've been developing an adaption layer that implements the functionality that I use in

over tables in Postgres that has a PRIMARY _key and a JSONB document field. The issue is that I have a number of prototypes I've developed with arangodb but the license is awful and I don't feel like I can either open source or commercialize any of them until I'm running on an open source database.

It's a fun project because I don't need to support everything in python-arango, in fact I don't even need to support 100% of the features I use because I am free to change my applications. Also it's a chance to make the library that I really want to use so already it has real integer and UUID primary keys.

I just added a feature to have the library manage _created and _updated fields not just because I thought it was good in general but it was a feature I needed for a particular application, a crawler that fetches headlines from the HN API. I want to fetch headlines right away so I can avoid submitting duplicates but I also want accurate counts of how many votes and comments articles got and that involves recrawling again in two weeks. Of course _created and _updated are helpful for that.
