Hi Joshi,
the problem may be that your traversal description will traverse from
actor to director (in both directions) and also from director to
actors (also in both directions).
Your "manual" traverser traverses actors to directors in both
directions and then only incoming relationships from dir

Hi,
there is still no difference in the performance, which is somewhat disturbing.
I cant't see the allocation of nioneo memory mapping in the java
process at all. It goes up to the heap size and then stops there.

Unless you are unlucky, and the index point
I have the same requirements on a project I'm working on. What I did was use
an abstract wrapper class for Node that helps with deletion.
protected final Node underlyingNode;
protected boolean isDeleted;
public boolean isDeleted() {
return isDeleted;
}
public void delete() {

I have graph of 2 types of nodes : actors and directors. The graph is
constructed such that an actor may have worked with multiple directors
and the director may have worked with different actors. The objective is
to find the list of actors (sorted by frequency) who have shared the
most number of d
Javier,
thanks for the feedback!
There is a strong desire for having some graph visualization in the
Neo4j Admin console, so - if you think it is interesting, I think
there might be a strong case for the projects working together on the
visualization component. I don't have the timeframe laid out

By now we are using only REST, but the performance is not what we

Hi Peter,
thank you very much for your quick reply, unfortunately there is no
messages.log, seems I have an older db version.
I'm sending you the ls dump from the directory:

The way I see it, there are two concerns here.
The first is focused at the lower levels, where the
WriteTransaction/LockReleaser discover an illegal operation - deletion
of an already deleted pri
An Node#isDeleted() method would also be fine.

Hi
I want to avoid keeping track if a node has been deleted or not.
How can I implemented this ?
I tried to simply catch the exception but then I can't commit the transaction.
Node node = db.createNode()
try {
node.delete()
node.delete()
} catch { }
tx.success
tx.finish // BAN
Hi there,
while Matthias is right in that the current REST API is exposing the
old Index API, for the next Milestone we are working on server
extensions which can execute Java and even Script code against the
running Server database instance and return both node, path,
relationship and custom repre
Marius,
could you send the size of the store files, the number of
nodes/relationships and your current neo4j.properties you are running
with? Examples and details are at

Hi,
I'm conducting experiments with two databases and have noticed a
radical performance drop when dealing with large databases.
I am working with dense triadic datasets, consisting of three node
types: A,B,C and hyperedges Y.
Basically one hyperedge y := (a,b,c) is stored in the db as 3 neo4j

Unfortunately the REST API isn't on par with the new index api, so REST
exposes the old IndexService. This will be fixed soon.
