Deprecation: The Neo4j
components are deprecated from the 8.0.1-R2022-11 Talend monthly patch.
Talend recommends you to migrate to Neo4jV4 components.
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.
Below is content of the CSV file to import data from in this
example:
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 WhitesAs 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.
