Hello everybody
A collection of reference benchmarks would be great, but completely independent
of this, my problem is making my application on linux as performant as on
windows.
Thanks guys,
Marco

Hi Bryce,
Nice to see you back.
The OSM data model in Neo4j-Spatial, created by the OSMImporter, is designed
to mimic the complete contents of the XML files provided for OSM. As it is,
this is not ideal for routing because it traces the complete set of nodes
for the ways, while for routing you re
Hey Peter,
Thanks for the awesome work!
On my end, on Mac OS X it's still not building though. I've attached the log
of mvn clean package.

Hi John,
I'm new to Neo4j as well, but I just want to put some thought on Ruby and
Neography. I had been trying to use neography and ruby to build a web
application the same as you wanted to do as well. But I found out that Java
with graph matching is very powerful and much more easier to use. And
Guys,
the plugin is now cloned to Neo4j,
https://github.com/neo4j/neo4j-gremlin-plugin and part of the build process.
I am waiting to get it built, there are some build before. Will post to the
list when you can download it (and use it with a Neo4j Snapshot build) if
that is ok?

Hello !
So, I'm trying to write a Java class to do a Batch Insert on my Neo4j
database, but I keep getting this error: http://pastebin.com/pdv4Lryh
The code looks like this : http://pastebin.com/xqytswMp
Any ideas what could that be ?
Any help is appreciated.
Milena Araujo.

Milena,
what versions of Neo4j are you using? What does your pom file or jars look
like?

Hi Peter,
I'm using the 1.4M02 version and my list of jars look like this:
geronimo-jta_1.1_spec-1.1.1.jar
mysql-connector-java-5.1.16-bin.jar
neo4j-community-1.4.M02.jar
neo4j-graph-algo-1.4.M02.jar
neo4j-jmx-1.4.M02.jar
neo4j-kernel-1.4.M02.jar
neo4j-lucene-index-1.4.M02.jar
neo4j-shell-1.4.M02.
Milena,
it seems you are lacking the lucene jar files. If you download a fresh copy
of Neo4j from neo4j.org, and look in the $NEO4J_HOME/lib directory, you
should find all the jars you need to get started with the basic development.
Otherwise, you can use Maven to pull the dependencies in, see
http
Yep, downloaded the 1.4M03 version and now everything works :D
Thank you very much, Peter.
Milena Araujo.

Hello everybody
The performance issue results from a too small transaction size. If I commit
only after 1000 traversials, the execution time for every traversial speeds up
to ~ 300 times. The same thing happens on windows where the speed is near
infinity :-). It seems, that there are two proble
Marco,
yes, small transaction require many disk flushes, so you are seeing the
limits of the OS IO. However, we are working on a MUCH faster mode of
relaxed writing, apart from minimizing the number of files to flush. We hope
to have these optimizations as part of 1.4, which means they will appear
I have some clue about this problem. I did face it before, though not
with Neo4j but with other programs that intensive use disks. For
example, my linux box completely frozen by svn update command for huge
projects. The symptoms are same : low CPU load with high iowait ( in

Peter, when this is ready can you post a quick 'how to' get this working?
Something like download the snapshot from X, git clone the neo4j gremlin
repository, run mvn package and copy it in the neo4j plugins dir.

Thanks Alexander for the info,
we should try to add this to the documentation for performance tuning at
https://github.com/neo4j/community/blob/master/kernel/src/docs/ops/jvm.txt
It would be great to add a section on tuning the OS for high IO. Just added
one :)

Hello All,
Experiencing errors with JSON parsing in neo4j-shell
Version neo4j-community-1.4.M02 running on 64bit SLES-10 with
Java 1.6.0_01-b06
I tried all manner of quoting the JSON but no luck.
Thanks in advance for any insight into this problem.
Peter, Craig,
Thanks for the info. I definitely would like to get this working & can spend
a few hours on it over the next couple of weeks. I'll probably follow up
with some more questions later in the week.

Hi Peter
Sounds interesting. I think small transactions are a common use case and being
able to use them would boost neo4j into new spheres :-)
Btw, congratulation for the whole project. Nice api, simple concepts. Well done!
