Neo4j: possible to create an alternative to node ids based on integer increments?

Neo4j's nodes tend to be set on the basis of integer increments. I can see this having issues in an application that needs to merge multiple two databases. Is it possible to configure the database to 开发者_C百科use another format, such as UUIDs to identify each node?

What I have done before is set a property on each node to store a GUID and created an index using the IndexService that creates a GUID index. I have then worked with that index to retrieve nodes based on GUID rather than the internal Neo4J generated ids.

No, it's not.

Here is a neo4j extension that adds uuid properties to each node.

Quote from the author why you should use uuid if you are dealing with multiple database:

... node.getId() is a bad choice since after deletion of a node its id might be recycled.
