Julien,
SDG also uses some 1.6 language features (but no classes that were only
introduced in 1.6) but I think the impact there would be minimized.
It uses AspectJ 1.6.x though, don't know if that relies on Java 1.6 features.
Will check with the AJ project lead.

I was considering using Spring Data Graph + neo4j to map my domain objects.
Since we have to deploy in multiple environment, I don't want to add an
extra layer of requirement for this.

Is your Concept also an interface?
Then you might try the same solution.
* either annotate Concept with @NodeEntity too.
* have Concept extend NodeBacked on itself
* elementClass should rather refer to the concrete implementation (this might
work with the interface though as it is just used to
Ok, just saw that this was resolved in the other thread. Please ignore this

Hi,
Is your application available somewhere, e.g. Github, so that we can try and
reproduce the error?
Thanks,

Hi Julien,
Have you considered using the stand-alone Neo4j Server?

Ok thanks for the info.
I understand your point of view given that Java 1.5 has reached end of life.
Unfortunately almost all J2EE application servers used in mission-critical
systems in production are still 1.5-based, and have not reached their EOL

Having an API that changes behavior based on configuration is a very bad
idea.
It makes the system very hard to work with.

What about a system config enabling/disabling loops? Then we could have
option 1, but for people that never loops, they can still get the extra loop
check by setting the system config option.

Kevin,
yes, this is certainly possible, but I would use Java, Javascript or Gremlin
to code it since the default REST callbacks are a bit clumsy to use in that
case. See Jims mail on how to do it in principle.

Hi Kevin,
There are a few tricks you can use to speed up accessing relations in a
supernode (like indexing them). But here I think you could design around it as
you've mentioned.
I agree with you that "worked with" maybe isn't an explicit relationship in its
own right either. It's an emergent
Peter, Jim,
Thanks for the responses. I think the issue is primarily driven by
traversals hitting highly connected supernodes. I am definitely interested
in options for handling this.
As I dig into it, I'm thinking some of the problem may be caused by our
graph design that creates many supernod
Thanks again MIchael,
I can compile my project, but I have still the error on my IDE, even after
installing AspectJ plugin on eclipse, as you suggested me in another forum.
Anyway, thank you so much

Hey Kevin,
Let's start to sleuth a bit. First question:
Is there perhaps a strong correlation between your slow traversals and paths
through the graph that touch the highly connected nodes?

Kevin,
I think there are two scenarios at work here:

problems? Part of it can be that the nodes need to be serialized into JSON

the problem is that the concrete class is annotated with @NodeEntity thats why
the interface MyClass isn't extended to extend NodeBacked
for elementClass you should use the concrete class

Hi,
We are using the REST API and are seeing slow performance on some path
traversals.
First some details about our data:
- 500K nodes (each with 1 property)
- ~15M relationships (each with a type, plus one or two properties) -- so
the 350K nodes are highly interconnected; but some node

Good point. I've just uploaded them to my website here:

Hello, first of all, thanks for answering.
If I have understood properly, it should work.
Here is MyClass definition:
@NodeEntity
public class MyClassImpl implements MyClass {

And my pom.xml,

Hi,
Yes, it has to be a special type. Your class has to extend GraphBacked (as
clearly stated by the error you are getting).
The AspectJ compiler will make your class extend GraphBacked automatically
if you have annotated it with either NodeEntity or RelationshipEntity.
The error you are experie
I have realized that the problem is not blocking. But if somebody could give

Hi Paul,
Neo4j "server" is just a remote API around the database engine with a useful
(and pretty) Web admin tool. It doesn't fundamentally change the database,
since the database is still embedded though it's embedded in "our" process
rather than "yours."
Which means you can run HA whether yo
