Stephen,
did you fork the code? Would be good to merge in the changes or at
least take a look at them!
Cheers,

Hi all,
I'm facing a situation to develop a multitenant graph environment. I heard
from some of you guys that this is planned for neo4j server. Is this neo4j
server only or will I also be possible to use this on neo4j embedded engine?

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

Tobias, thank you very much for your quick response.
Hi Dima,
Estimated number of relationships is ten times number of nodes, which makes
it 20 billion. Number of properties for each node is ~10 and for each
relationship is ~5.
Currently
Hi Craig,
In my application the user clicks somewhere on the map,
then I need to find the closest waynode to the mouseclick-position.
Can this be done by the procedure I described earlier?
My definition of neighbour nodes:
Let's say we have nodes from n1, n2, ... n9
Then we have the ways w1 and
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
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
Hi Ville,

Hi there,
I am somehow stuck with a problem of combining traversing and queries
to indices efficiently - something like finding all people with a name
starting with Vil* two steps away from a reference node.
Traversing all friends within
Would it be also possible to go the other way round?
E.g. have the index-results (name:Vil*) as starting point and traverse
backwards the two steps to your start node? (Either using a traversal or the
shortest path graph algo with a maximum way-length)?
Cheers

I've taken part writing an application very similar to yours, with
organisations, groups, users and content... and security on those. The
security model it uses in the graph is something like

Georg,
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:
Looked over the configuration properties I mentioned, and it seems I was
incorrect, am unable to reproduce the problems I saw before. Doing something
like:
org.neo4j.server.webadmin.management.uri=/asd/
Will make the server move management stuff to that URI, and webadmin will
follow suit. So for
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
Hey Jake,

Will make the server move management stuff to that URI, and webadmin will
follow suit. So for your case, you should be able to do:
org.neo4j.server.webadmin.data.uri=/neo4jdb/db/data/
org.neo4j.server.webadmin.management.uri=/neo4jdb/db/manage/

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
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
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:
-
Hello group,
I just realized that since upgrading to Neo4j 1.3 my deployment is broken.
It seems to be due to the fact that when starting up, the server does not
return to a prompt (I noticed this locally also - I need to press enter to
get the prompt). Vlad (the deployment script) thus probably
Hello group,
I've been using Neo4J for quite a while now but I reached a point I need
some help: I have an ontology and I would like to model my neo4j nodes
(the ones I will create) based on properties, classes, etc from my ontology.
I'm also using JENA API for this purpose (to get information
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
