[Neo4j] Re: Connecting Neo4j with R

Hi, There is some ongoing work on Neo4r regarding 4.x support. I believe Neo4r should still work with Neo4j 4.x, as the REST APIs it uses are still there. If you find that is not the case, your next best bet would be to try this pull request and see if it works: https://github.com/neo4j-rsta

Re: [Neo4j] Is there anyone using versioning / database migration on neo4j?

Hi, I'm currently working on the issue with Stanford NLP, it's probably just a classpath conflict with JAXB. If you really want to programmatically create migrations, you can, using directly `liquigraph-core` and instantiating `Changelog` objects, but this will require some extra efforts. I think

[Neo4j] Pessimistic locking in Cypher

[Neo4j] Re: When not to use Neo4j

I would say whenever the data set cannot fit on a single machine. This is not a definitive nogo as you can always shard the data yourself and spread across several (preferably co-located) Neo4j instances but this is far from ideal in most cases, I guess. On Saturday, 9 May 2015 11:07:15 UTC+2,

Re: [Neo4j] newbie help please: neoclipse displays no nodes in graph

This not a direct reply to your issue but why don't you use Neo4j browser? It is way more user-friendly than Neoclipse. On Sunday, 22 June 2014 02:28:52 UTC+2, Jeremy Posner wrote: > > > any reply please ? > > thx > > On Saturday, 10 May 2014 10:10:22 UTC+1, Jeremy Posner wrote: >> >> thansk for

[Neo4j] Re: Current Store File Composition

Hi, The presentation you are mentioning is already 2 years old (therefore pre-2.0). I have recently blogged about this (in FR tho: http://florent.biville.net/?post/2014/06/09/Neo4j-sous-le-capot). I think the reference source remains the manual as you said, but you could also check Neo4j sour

Re: [Neo4j] performance with many relationships per node

Sorry to reply to this old thread, but I'm actually facing the situation you're describing at the end: having possibly many rels to traverse. As you mentioned, the fix in 2.1 won't fix this and there is the workaround you describe above or even, as Mark Needham and Cédric Fauvet told me, the pos
