Re: [Neo4j] Server couldn't start after java.lang.OutOfMemoryError

Hey Adriano and everyone, I finally got a chance to monitor/profile the neo4j process with VisualVM when I run my set of tests. It seems that after running the set of tests once, ~ 50M of PermGen was used. However, subsequent test runs simply multiples that, which worries me a little. After th

Re: [Neo4j] Index entry removal after relationship deletion

Thanks. That was what I imagined too. However, I have a test that does: 1. create two nodes (e.g. node 2 and node 3) 2. create a relationship between the two nodes (e.g. rel id 23, type :foo) 3. add the relationship to the foo_rels index, with 2 as the key, 3 as the value (the node ids) on rel id

[Neo4j] multiple lucene index in a transaction doesn't work?!

I've searched around the forum, and aware of people who are using different indexes for optimization. I am trying modify the EmbeddedNeo4jWithIndexing.java from the samples directory so support multiple indexes and I kept on getting exception whenever I try to commit the transaction. My use case

[Neo4j] Index entry removal after relationship deletion

Hey guys, When a relationship gets deleted, will it be removed from the index automatically? My test shows yes, but I want to be absolutely certain. For example, a relationship :foo exists between node A and B and it's indexed on the foo_rels index with key node_a's id and value node_b's id. When

Re: [Neo4j] [Spring Data Graph] Some questions/suggestions about cross-store persistence

Hi Michel, sorry just returned from vacation. the problem with 1) is still - you have to start to define fetch-groups for subgraphs etc and you also have to define cascading rules for updates of relationships. Right now I don't have the resources to add all these things (especially as the dev

[Neo4j] Neo4j Spatial - GeoProcessing in the making

Hi all, while trying to come up with a good approach to GeoProcessing in Neo4j Spatial as we wrap up Andreas Wilhelms work from the GSoC, we are experimenting with a dataflow-based lazy approach (using the generic parts of Tinkerpop pipes). This is broken up into filtering operations (that filter o

Hi Dima, and regarding your second message, the NotFoundException for the phone property, what happens is that, on the beginning you had some nodes without the phone property, and some time after, nodes were created with this phone property, and that's a good thing, each node can have it's own pro

Re: [Neo4j] Unable to being transaction

Like Bryce mentions, this is due to a problem the transaction manager has encountered, there should be an exception from it sometime before these stack traces show up. If you are able to, look further back in your logs for output from org.neo4j.kernel.impl.transaction.TxManager, there should be a

Re: [Neo4j] Webadmin with embedded neo4j on tomcat 6

There is no specific workaround for launching the server from within another web container. It looks like there is a ServletContextListener hooked up for java server faces, that triggers when neo4j servers' Jetty instance starts a webapp context, and subsequently fails. I'm assuming the JSF listen
