Hi Bob,
What happens here is that you perform a tiny operation in each transaction,
so what you are really testing here is how fast your file system can flush,
because with such tiny transactions all of the time is going to be spent in
transactional overhead (i.e. flushing transaction logs to the

Hi,
Using Neo4j 1.3 and the Borneo (Clojure) wrapper I'm getting radically
different performance numbers with identical test code.
The test is a simple-minded: create two nodes and a relation between them. No
properties, no indexes, all nodes and relations are different.
On OS X, it takes abou

Even at this stage in the planning, I can see that story written down :-)

Hey Jake,
So would you be in favour of removing the discovery document in favour of a
server-generated index.html? Or perhaps making it richer (e.g. here's the
discovery document pertaining to this "host" header)?

I'd guess that isn't possible. You'll have to make sure you index your
stuff with all lower or all upper (preferably lower), or use lucene
analyzers which does that behind the scene. In Neo4j your lucene
fulltext indexes does that for you automatically.

Hi Ville,
We ran into a similar problem basically wanting to search only part of the
graph using Lucene. We used traversing to determine the nodes to search from
and from there on use Lucene to do a search on nodes connected to the nodes
from the traverse result.
We solved it as follows:

Hi,
I've written a step-by-step guide for installing Neo4j on OSGi (

It is based on my own experience and currently it shows how to install Neo4j

Oops, I realized I just lied.

does not return the "discovery document"* that tells it where to find

I am playing with release 1.3 (nice work!) and trying to get the PHP REST
implementation to work with the new named indexes. I noticed there is no
way to delete an index using the REST API?
>From the java api I think this would be analogous to Index.delete()?
In the wild maybe it wouldn't be use
Yup, I think that's the case, glad to hear performance is good. I'll take a
closer look and get back to you.

1) Plugins can only expose REST endpoints that are added to node, relationship
and graphdb URIs, return types are restricted to nodes, relationships, paths,
primitives and collections thereof.
2) Extensions can add arbitrary REST endpoints.
You could also write an Extension that sets up its own

here is the case which I want to count total number of nodes and dragging
only some level (in between) of nodes from total.
The sample code looks like this:

try{
td = Trave
I have no problem writing it :). So plugin can expose anything it
likes and it will bootstrapped by the server when starting/deploying ?

It can be, but we don't have such a binding at the moment. This will be
something you'd have to write for yourself, or (sadly) wait until a later
Neo4j release.

Hi Reinhard,
The PointResult you get from your previous procedure should contain a Point
instance with the coordinates of the closet waynode, which you can get using
result.getKey(). If that at all you need, then you are done.
However, if you want to do more with this result, for example you want

Dima,
yes, you can write Server Plugins (and Extensions) and then just put those jars
in your servers plugin directory.
They will be picked up and be available as REST endpoints for your client
applications to consume.
Those can also be implemented on top of your domain model, so that you don't

Like you noticed and like Jim mentioned, the server will pick up on the
domain you are using, but the actual URI structure is "fixed". You are
supposed to be able to change the mount points for the various server
components, by setting these properties in your server config:

If you by multitenancy simply mean that you want to have multiple separate
graph database, you can do that as easily as:
GraphDatbaseService graphdb1 = new EmbeddedGraphDatabase(
"/path/to/your/first/graphdb" );
GraphDatbaseService graphdb2 = new EmbeddedGraphDatabase(
"/path/to/your/second/graphdb
Yes,
that seems to be the least complicated solution. But I'm think in a more
complicated way :) In need a graph model that will combine multi-tenancy
problem with authorization problem in each tenant.
I think that these two problems are similar: both a tenant (organization)
and a user from that

Hello,
Multi-tenant in a graph can be easy: simply use a different sub-graph for each
tenant and let your application code bind to you a specific subgraph.
If you want to go to the next step and have physically separate databases,
that's harder. Are there reasons for wanting to do this, such as
Hi all,
