Linan,
I think your example would be great for doing a JUnit test showing
this. Niels, could you do that, plz? In that case, I can add a
graph and exaplanations to it.

how about i put the codes onto github and you guys can comment and
modify it. then include the project as a sample?

Hi. I'm just starting with neo4j, doing some pocs and investigation.
I'm using spring data to persist my data. And so far I was able to both
persist and load data from the db (from my unit tests anyway)
I've added a few nodes (250) and also created some relations.
But, when opening the

any idea?

Spring Data Graph stores the type information in the graph.
The default is to use indexes to store this information, but it can also be
stored as type-nodes with relationships to all instances.
The current neoclipse supports index lookups, so please try the following:
the index name is:
Could you share the content of the mesages.log file in the database directory ?
Also do you sometimes kill the neo4j instance abruptly with kill -9 or similar
? That can cause corruptions of some lucene files ?
Thanks

if you find that code useful, maybe we could bring it to GIThub. since

That sounds perfect! Just make a fork on the graph-collections and let

Peter,
I'd gladly put out a piece of code demonstrating the use of IndexRelationships,
using this LIVES_IN example. Though I get the impression the question here
relates to the normal relationship index. However when supernodes (still
don't like that term for densely connected nodes) come

That solved the problem. Glad that I can see my graph now.

Hi,
I have the following problem: when my program crash in the middle of the

following exception.

Very cool Christopher!
We are testing to pull in some of the bindings for Neo4j into the
manual - would it be possible, when things stabilize, to pull in the
Scala bindings to the Neo4j repo. build them and start documenting
some test cases so we can put them into there, too?

Marko,
in principle, you can without much overhead. Be aware that you will
run into problems, since some operations are not implemented (like
indexing), and some that could be implemented (like change properties)
are not, either. So, try it out, but remember - you have push rights
to the repo, so

According to this:

as well.

Yuanlong,
what is Webbench you are using? Is your graph warm in the caches?
You are right that paging in Cypher is not implemented - you are
issuing a new query every time. However, what is the timing you are
experiencing if you do the query, but only return the first 10
results?

Hi,
I would do this using Gremlin as such:
g.v(1).out('read').in('wrote').uniqueObject.out('pet').name
If you are vertex 1 (g.v(1)),
then you will go to the books you read,
then to the authors of those books,
then because you might have read two Stephen King
Hi Guys -

Hi,
This error seems to be an issue with depedencies. Are you using an TinkerPop
dependency/s in your project. I believe Neo4j 1.5.M01 is depending on
Blueprints 0.9 which does have the getInEdges(String...) method (similarly for
getOutEdges(). Perhaps you are depending on Blueprints 0.8

Yup,
Don't upgrade dependencies right now before Gremlin 1.3 is out and can be

Xavier,
this can well be a packaging problem. Could you try with 1.5.M01? The
dependency problem is fixed, but we are fighting for the build
pipeline to deliver a new snapshot of the final artifact.

Actually i'm fine with nesting multiple traversers to solve the
problem if deep inside gremlin, evaluator and fluentPipeline are just
nice constructs over the same solution. is it correct?
thanks

Thanks! I really appreciate.
Linan,
yes, deep down Pipes are composing the pipeline out of iterators to
the base API operations node.getRelationships() and
relationship.getNodes() . The Neo4j traversal API is using callbacks
instead. What you want to use depends on your taste :)

Hi folks,
just commited some example code to show the use of
Uniqueness.NODE_PATH in the Neo4j traversal framework in order to
return paths that share nodes.

hi,
I once read a blog about how long it take for computation operations
such as read from L1 cache, RAM access, send packet from usa to eu,

operations, we have better control. for example, in my project i also

Hi Linan,
These are good questions. I am currently following a similar approach to
characterizing the performance of basic graph operations, and then also simple
graph algorithms on various shapes of graphs. My initial investigation is on
small graphs on my laptop, but this weekend I'm testing

Fair enough. For now, I'll just know not to try and make batches that big
:-) My own use case is for the transaction safety rather than trying to
create thousands of entities at once, so it doesn't effect me that much.
