Re: [Neo4j] Embedded or Standalone?

2011-08-28 Thread Peter Neubauer
Aman, Generally speaking the embeddded use of Neo4j is fase since there is no network serialization overhead -the database runs in-process and is thus much faster. However, the core engine in both versions is the same so how big the network penalty is depends very much on your domain and use case .

[Neo4j] API adventures in Scalaland

In the last week I have been working on a Neo4j API in Scala, taking navigation in the graph as primary. Just like the Enhanced API written in Java, the Scala API generalizes each element (Node, Relationship, RelationshipType, property name and property value) of the Neo4j database as being a

2011-08-28 Thread Jim Webber
I suspect (though I haven't profiled it) that the decreasing performance of batches could be due to JSON processing. If so, we're going to have to switch to some kind of streamed approach for the REST batch API. I'll add these notes into the job in the community backlog. Thanks very much Josh!

Wow. That's surprising data. With Neo4J embedded, we can usually get about 100X of that performance (including Lucene indexing of the nodes), so there clearly seem to be some big impacts from using the REST interface versus Neo4J embedded. -Original Message- From: user-boun...@lists.n

Here are the latest benchmarks of batch vs. individual entity creation using the Neo4jPHP library. Most of the processing time is spent on the server, so I believe that these numbers are probably not specific to Neo4jPHP. I'm not implying that there is anything wrong or to be fixed; I just though

Hello, Note that with loadFile(), you are not incrementing your commit manager's counter and thus, if your RDF file is large, you may run out of memory. See the work of Claudio for a good model for large RDF graphs: http://blog.acaro.org/entry/dbpedia4neo https://github.com/clau
