Import Distinct Data With Relationships

Import Distinct Data from a CSV file, and create relationships

Here is an example of importing distinct data from a CSV file, and creating relationships using that data.

This method is more efficient than just using MERGE. It never tries to match any duplicates from the csv file as they are filtered out beforehand. It still uses MERGE to ensure that duplicate nodes are not created, but in this situation this would only be required if the csv file was loaded more than once.
