Using Neo4J 2.1.5. Data:
- 2000 Persons - KNOWS relationships between some of them Goal of the query: For each person, display her fullname + amount of friends + amount of friends' friends + amount of friends' friends' friends. MATCH (person:Person) WITH person OPTIONAL MATCH person-[:KNOWS]-(p:Person) WITH person, count(p) as f1 OPTIONAL MATCH path = shortestPath(person-[:KNOWS*..2]-(f2:Person)) WHERE length(path) = 2 WITH count(nodes(path)[-1]) AS f2, person, f1 OPTIONAL MATCH path = shortestPath(person-[:KNOWS*..3]-(f3:Person)) WHERE length(path) = 3 WITH count(nodes(path)[-1]) AS f3, person, f2, f1 RETURN person._firstName + " " + person._lastName, f1, f2, f3 This query lasts long ! : 60 seconds ! Is there a tips to optimize it? Thanks, Michael -- You received this message because you are subscribed to the Google Groups "Neo4j" group.
