Thank you for your response. I'm trying to understand the main concept, please correct me if I am wrong.
For example, there are many users of an application and each represented as "Node". And each User has a "UserId" in RDBMS. I have checked "Node" class and saw that there is a method called as " getId() " but I could not see "setId()" for mapping the User in the RDBMS to neo4j. Sample data: (UserId / Friends Ids) 1 - [2, 4] 2 - [1, 3] 3 - [10] 4 - [1, 3, 5] 5 - [3] And I need to query " What are the all shortest paths from 1 to 10 for max length 4 " And results should be, 1 -> 2 -> 3 -> 10 1 -> 4 -> 3 -> 10 * 1 -> 4 -> 5 -> 3 -> 10 (It will not be shown because it exceeds the length 4). You mean that it can be handled with neo4j, but how can I map each User in RDBMS, to Nodes by their original Ids?
