I'm working with neo4j version 3.1.3 neo4j import tool START_ID/END_ID is possible to pass another field and not the id of the Node ? make a match between another property the START_ID and END_ID I know that in cypher it's possible but i need to start the graph with import tool because there are large files and take too much time to insert the data to neo4j through cypher. Thanks in advance

The :START_ID and :END_ID in the relationship csv files have to be an :ID in the node csv files. These have to be unique, there's no other way that a correct match (read: a correct relationship) can be made.

You can read the exact specification (and reason why things are the way they are) in the first paragraph of https://neo4j.com/docs/operations-manual/current/tutorial/import-tool/.

Hope this helps.
