[Neo4j] Connection Pool in Neo4j

Hi, I have just started using Neo4j. I was wondering if Connection Pooling has been implemented in Neo4j ? I could not find any helper classes or any sort of documentation on it. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman

[Neo4j] How to connect Neoclipse remotely

Hi, I just installed Neoclipse. I am trying to connect it to a graph remotely. I see an option to enter the "Database Resource Uri" but that box is not enabled and hence I do not know how to connect the database. I have both Neo4j-1.2 and Neoclipse-1.2. Also do I need to have Neo4j locally to use

[Neo4j] Neo4j + Rexster lock problem

A similar question has been asked previously but I could not find a solution which would work for me, hence re-posting it. I am creating a Neo4j graph and want to expose it over REST using Rexster so that I can apply traversals to it. Now after I have started Rexster, I see that I cannot write to

[Neo4j] Neo4j with MapReduce inserts

I am trying to write MapReduce job to do Neo4j Batchinserters. It works fine when I just run it like a java file(runs in local mode) and does the insert, but when I try to run it in the distributed mode it does not write to the graph. Is it issue related to permissions? I have no clue where to look

[Neo4j] help for Traverser

Hi, I am trying to create a traverser and I am stuck. So my code takes in a startNode, 2 relationshiptypes and 2 directions. It will starting from startNode go to nodes with rel1 in dir1 and from all those nodes to rel2,dir2. The code below (in SCALA) works fine and I get the expected nodes. The

Re: [Neo4j] help for Traverser

Thank for the response. So I was doing exactly what Mattias suggested, but I thought that this might not be the most optimal way. Though, since I got a validation I would stick to that method. On Fri, Jul 22, 2011 at 11:37 AM, sulabh choudhury wrote: > Hi, > > I am trying to create a

[Neo4j] TTL or node expiry available ?

Hi, I was wondering if there is any notion of TTL in neo4jcan a node/ relationship be automatically deleted after a certain amount of predefined time ? ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

Re: [Neo4j] TTL or node expiry available ?

The approach is to set the expiration as one of the edge's properties and during traversal check if the "expiry" time has passed or not. But if there were something like a TTL where the edge expires and removes itself I would not need to check it. On Fri, Aug 19, 2011 at 3:41 PM, sulab
