I run into the same issue when starting my test-server from the commandline.
Checked that the neo4j-lucene-index-1.3.M02.jar was there with the correct
index provider in META-INF/service/org.neo4j.kernel.KernelExtension
Any ideas Mattias?
Thanks

Sorry, didn't see your mail (had Andreas' still open for replying).
It worked, thanks very much. But funnily the lucene jar is not recognized as
dependency by maven for the server (mvn dependency:copy-dependencies). I assume
it is added by the server-build project?

Hi David,
Great to hear you're interested in using neo4j for the OSM model. I also
think it is a great match. However, you are right to assume there are a few
missing pieces. Two shortcomings that are relevant to your questions below
are:
- *Scalability*. We only recently tried to load very
Hi!
This is included as a dependency:
org.apache.servicemix.bundles:org.apache.servicemix.bundles.lucene:jar:3.0.1_2:compile
That's an OSGi-friendly packaging of Lucene.

Thanks Mattias David.
Yes, am doing tx.success() and tx.finish() when I commit.
I also noticed that once I get IllegalStateException, I cant search for any
nodes from the graph index.
Here's my code snippet when create,index and commit the nodes also when
delete the nodes:

David,
as Craig mentioned, we are in the process of profiling insertion into
Neo4j Spatial. From the volume side of things, Germany.osm consists of
roughly 60M points and 8M ways (a common pattern, even other sets have
roughly 10% of the nodes in way count).
From the file sizes, planet.osm is 10
Then,
you would like to get all the paths that containing any number of
single occurrences of REL1...REL4?
In that case, I would from the current end of the path, look one
relationship further (path.endNode().getRelationships()), and
EXCLUDE_CONTINUE include the path if the at least one of the
Mmmh,
the main issue here I suspect is that the Java Service Loader is not
finding the META-INF/services files. It might be that it is not
triggered when you add files dynamically to the classloader. That is,
the JARs are only scanned at startup time for any non-class files.
Could that be an

Hi Massimo,
It's too bad you are running into the same kind of situations, (specially
when
the conclusion you came up to is that Neo4j just degrades...).
However, did you already try dividing the big insertion process into
smaller
steps?
I mean, do you think Neo4j degradation is just proportional

Hi!
Jacob started working on a proper deb packaging for Neo4j here:

Me and Jacob would love to bring Neo4j into the Debian package
ecosystem, but it seems we need at least some guidance from a Debian
developer.
So - are there any Debian

Should I move the server or the client or both to Linux or Mac to avoid the

I prefer to keep the client on windows if possible.

Brendan,
I am plowing through the Neo4j tests on windows and have seen some
files not being released on shutdown of the DB, namely messages.log.
Hope to get it prioritized tomorrow, but meanwhile, could you try a
linux server and see if the problem persists?
Cheers,

NO! ;-)
We have to get all of the Windows-specific issues dealt with sometime soon,
as there will definitely be some deployments on Windows (we're a mixed
Windows/Ubuntu shop right now).

Marko,Thanks for the help. I've had a chance to play with the gremlin shell a

Thanks for the response; this looks quite helpful. I will write and run some

performance and identifying further improvements that are needed for my
