Importing data from a CSV file to Neo4j and creating relationships using a single Cypher query (deprecated)
This scenario applies only to Talend products with Big Data.
This scenario describes a Job that imports family information from a CSV file into a remote Neo4j database and create relationships between persons and families using a single Cypher query through a tNeo4jRow component.
Name;Gender;Age;Family
Jenny;Female;24;the Johnsons
Jack;Male;26;the Johnsons
Richard;Male;35;the Blacks
Anne;Female;36;the Whites
Helen;Female;28;the Blacks
Tom;Male;38;the Whites
As MERGE is used with LOAD CSV in this example, to ensure the Cypher query is executed in an efficient way, another tNeo4jRow component is used to create an index on the property to merge.
