Creating Relationships between graphs (Fabric, Shard, other?)

[dthusma]

Does anyone have any experience, documents they can point me to regarding creating relationships between graphs?

I have the following graphs: Trucks and Cargo. They are separate graphs due to internal policy, so merging into one graph is a no-go.

I need to assign a relationship between a cargo load to a truck. Is there an elegant way to do this with Relationships? Right now, I am using fabric and using the node IDs to make it work.

Hoping there is a barney-level answer out there I just missed.

Looking forward to the responses.

Hey @dthusma ,

You can't create a relationship across databases in Neo4j, so in this case you'll need a reference to the Trucks in the Cargo database or vice versa. It depends on your internal policies I would suggest having a Truck node inside the Cargo database holding only an ID property (eg. a UUID or the vehicle registration number). Then, if you need more information about the truck, you would then query across into the Trucks database using that ID
