Hi, Attended the Neo4j meetup in London last night, and wrote up my thoughts here: https://dankeeley.wordpress.com/2018/10/25/neo4j-london-meetup/ Always good to know what others thought, and what particular things other people find interesting. Any other attendees here? Dan -- You

[Neo4j] Which internal module responsible for verifying WHERE conditions from cypher?

My goal is to add to neo4j engine additional filtering, which will verify every node and relationship for property. This will give ability to break graph to subsets and perform random queries in different "layers" on demand. According to this answer

Re: [Neo4j] Label Performance

akes the queries a tiny bit more complicated to search by property, but I guess its not too bad (SuperLabel)-->() vs. (Label {is_super:true})-->() Thanks, Dan On Sunday, June 7, 2015 at 4:30:53 PM UTC-4, Michael Hunger wrote: > > > Am 07.06.2015 um 20:57 schrieb Dan R >: >

[Neo4j] Generate top "n" for each group via a Cypher query

rder by Count desc limit 5 UNION match (n:Entity)-[r:IN]->(d:Doc), (d)--(n2:Entity) where n.name in ['C'] return n.name, n2.name, count(*) as Count order by Count desc limit 5 But my question is can a single query be done (not using a union) to generate the same top "n"

[Neo4j] Neo4j GraphDatabaseService.isAvaliable(long timeout) - What Is It Actually Checking?

We're using v 2.1.7 of the community version of neo4j and we are trying to understand what the call to GraphDatabaseService.isAvaliable(long timeout) is actually checking? And will it detect a Deadlock condition? When navigating into the implementing classes, they seem to all be deprecated - I

I'm having trouble getting neo4j to work with my own SSL certificates (this is both on Windows and Linux). When attempting to start server it sits at log entry "Enabling HTTPS on port :7473" for around 7 seconds and then terminates with no error message. So, I'm not sure if there is a problem
