Need advice: keeping graph data segmented by user

[Henry Hwangbo]

I have an interesting situation. I am allowing users to provide their own data sources to be imported into neo4j. The data sources could be the same across different users, but I would like cypher queries to only query nodes and relations specified by a particular user's sources.

I can think of several ways to do this:

1 separate neo4j instances for each user
2 tag nodes and relationships by user

Currently node duplicates are prevented by indexes so I would have to alter that approach since nodes which already exist simply cause a new relationship to that node. Number of relationships to a node are used in my analysis so separating relationships by user are important.

Perhaps just tag relationships?

Thoughts appreciated.
