Re: [Neo4j] [Neo] Is neo4j a good soultion?

A quick comment about transaction size. I find a good speed/memory balance at a few thousand writes per transaction. More than that improves performance with diminishing returns. 2010/5/17, Mattias Persson : > 2010/5/17 Kiss Miklós > >> I enabled the lucene index cache for the mostly used propert

Hi, Okay. I just removed it from Blueprints and everything compiled and all the test cases passed. Thus, all is "perfect." :) Thanks, Marko. On May 31, 2010, at 9:20 AM, Mattias Persson wrote: > To clarify: the Isolation levels (and implementation of it) in index > service had a lot of problem

Re: [Neo4j] Isolation Level.

To clarify: the Isolation levels (and implementation of it) in index service had a lot of problems which should've displayed themselves if someone actually used them. I saw that blueprints used Isolation.SAME_TX which is the default (and the only useful isolation, looking at the code). Based on th

Just don't use it and you'll be fine 2010/5/31, Marko Rodriguez : > Hello, > > The following method seems to have gone away from the Neo4j API: > > LuceneIndexService.setIsolation(Isolation.SAME_TX); > > Just comment it out and no longer use it? Or has it morphed into something > else? > > Thanks,

[Neo4j] Isolation Level.

Hello, The following method seems to have gone away from the Neo4j API: LuceneIndexService.setIsolation(Isolation.SAME_TX); Just comment it out and no longer use it? Or has it morphed into something else? Thanks, Marko. http://markorodriguez.com http://tinkerpop.com ___

Ciao Peter, It's not easy to provide you a test case suitable for debugging ... I'm running many test to complete my thesis (I'm citing neo4j) on some natural language processing problem. My dataset is very large. Let me think about it If you can access the sources of 0.3 stable version, you

[Neo4j] neo4j vs. mysql

Hi! A study was recently published, comparing Neo4j and MySQL from a data provenance perspective. The paper can be downloaded from here: http://john.cs.olemiss.edu/~ychen/publications/conference/vicknair_acmse10.pdf Nice to see that graphdb gets more coverage in the academic world! /anders _

[Neo4j] Apoc OSGi packaging updated

Hi all, just wanted to say that I yesterday updated the APOC-OSGi bundle packaging for Neo4j, https://svn.neo4j.org/laboratory/components/apoc-bundle/ . It even includes Karaf-features for Neo4j, so let me know if things are working out now. However, Pax Exam is not available in a SNAPSHOT version

Re: [Neo4j] Performance of shortest path algorithms

Hi Tobias, Johan just updated some of the tweaking documentation for Linux at http://wiki.neo4j.org/content/Linux_Performance_Guide . As you can see, you can warm up the file caches in Linux, and of course write some routine that pre-loads nodes into the object cache in Neo4j. For your second quer
