Hi, I am trying to find the shortest distance between 4752 nodes and 1098 relationships using the below query CALL algo.allShortestPaths.stream('Number_of_associated_posts',{nodeQuery:'skill',defaultValue:1.0}) YIELD sourceNodeId, targetNodeId, dista...
I installed the neo4j Debian package from the debian.neo4j.org/repo stable/ repo on Ubuntu 18.04 and, after adding my TLS certs, it ends up getting stuck in a restart loop with no indication in the logs of what's making it shutdown: 2019-03-09 23:29:...
Let me take simple question. I'm counting the number of nodes and relationships per labels and types. I successfully can count nodes like this query. CALL db.labels() YIELD label CALL apoc.cypher.run('MATCH (:`'+label+'`) RETURN count(*) as count',{}...
I feel like I'm being stupid, but I can't figure out how to conditionally call a (custom) procedure, and ensure a valid number is returned. Here's what I'm trying: MATCH (a { uuid: "bad-uuid" }) RETURN CASE WHEN NOT a IS NULL THEN CALL specialDe...
