I want to create a composite primary key named "ID" as
ID = emp_id + "_" + date_of_joining
I prepared my data by concatenating two columns and creating ID field. Then using ID field as a primary key in export nodes recipe. Please refer to the attachment.
Is there a more straight forward way to define which columns I need to use as a composite key and providing a name for it in recipe, rather than preparing the data manually? Does neo4j handle this itself and provide an option like it does for defining primary key?
