Neo4j Writer

StreamableNeo4jconnector version 1.0.0.v202007061010 by REDFIELD

The node allows user to populate Neo4j with the data.

  • Script - active when there is no input table connected. User can create a Cypher script with injections of labels for nodes and relationships, and available server functions to populate the database.
  • Schema is fetched with functions db.labels, db.relationshipTypes, dbms.functions.
  • Query from table - if the table is connected, then user can select the string column that contains Cypher queries. Output will always be a JSON column.
