Tips and Tricks for Graph Data Modeling

[@mizu643]

Could you please let me know the difference between SET in groups.cql and ON CREATE SET in topic.cql?

[@neo4j]

You're best asking these types of questions at community.neo4j.com/
On a MERGE statement, SET can be used to always SET the property whether or not the pattern previously existed or not. ON CREATE SET will only set the property if a previous matching pattern/nodes were not found in the database and it is newly created as a result of the MERGE. See neo4j.com/docs/developer-manual/current/cypher/clauses/merge/
