I am trying to build a distributed AI. It works on graph and most of its problem relies on the database. I need an SQL database that supports graphs ( or I can make it support) I need node locking or atomic increment support Most importantly I need persistant keys for every node and link in the graph. Most graph databases don't give a persistant key. I have tried some of the databases like Neo4j but it lacks persistant key and also I can't change a link's first or seconds node. My writes and reads are nearly equal and I am adding more node and links during runtime so Pregel like graph processing don't work for me. Do you have any suggestion?

by persistent you mean that the database is append-only? or something like that? – amirouche Nov 08 '16 at 20:33
