Is there a way to save and restore neo4j graph database states (other than by using transactions)? Of course, I know that there is a backup mechanism, but I am looking for something faster, something that can be used programmatically. Flat nested transactions (as provided by neo4j) do not

*RESOLVED* 1. Tutorial ( http://neo4j.com/docs/3.0.1/ha-setup-tutorial.html ) is somewhat misleading. Thanks to Dave from the neo4j's team for the info: you NEED to set ha.host.coordination and ha.host.data I'm in AWS. In my config these values are set to Internal instance IP, with 5001 port

[Neo4j] Anybody currently using Neo4j with Django?

I don't see much fresh data here or on SO. I tried to set up a new project in Django (my preference) and ended up moving over to Flask. I miss the robust Django ecosystem for everything else, but using Django without the ORM is also a pain. Advice? -- You received this message because you

Re: [Neo4j] Shortest path using query

If you want the shortest path to interpret the length of the path based on a cost function (for example shortest route on the map where the length of the roads is the cost), then the 'shortestPath()' function is not the right one. It can only consider all relationships as having the same weight

Re: [Neo4j] Shortest path using query

What if I would like to get all shortest paths with the lowest cost without knowing how much this could be. I think by adding the query rel.cost < x will not work in this case? Op dinsdag 17 mei 2016 22:23:37 UTC+2 schreef Michael Hunger: > > Just add a WHERE clause (at least in Neo4j 3.x) > >
