aws neo4j replication across regions

Question

Does anyone have any idea how to do a master to master replication of neo4j on AWS in different regions? I need to have one neo4j DB in USA, Asia, and Europe and I would like that my apache application connects from Europe to Europe Neo4j, USA to USA Neo4j and Asia to Asia Neo4j. For that, I would need that all 3 Neo4j be constantly synchronized.

Neo4j supports multiple datacenters. You basically organize your instances in groups indicating their location. The client then uses eg bolt+routing://someneo4jhost.com?policy=europe to indicate it want's to use servers of a specific group.
