I got Neo4j V1.2 installed and running on Win 7. Yea!
I was able to access the admin pages and run some sample CURL commands to
verify the installation with http://localhost:7474.
Questions:
1) So now, I have one database that I might want to continue to play with.
How do I create the second da

Yes, actually, it just did for me. I just blew away my ~/.ivy2, my ~/.m2
and tried again, getting the update failures. Adding the JBoss
repository helps.

Not necessarily. If, by chance, you know how many vertices you will be
returning, you can using a sampling appro
Charlie,
As Michael duly pointed out, the traverser is a lazy iterator, so you can
simply just pull the first N results from it.
In order to get a random node you'd need to know the full result set.
Alternatively you can make your traverser go in random directions and that
way get a random result
As the traverser returns its results lazily you can just stop after N nodes
(for embedded mode).
If you talking REST-server there is currently no such limitation but REST
improvements are worked on.
You can easily write your own server plugin or addon that does this, though.

I believe you can tie in to returnedNodesCount()
http://components.neo4j.org/neo4j-examples/1.3.M02/apidocs/index.html?org/neo4j/graphdb/StopEvaluator.html
@neo.traverse(school,"nodes", {"order" => "breadth first",
"uniqueness" => "node global",
Is there a way to limit the number of results that are returned from a
traverse? I have a traversal
that returns thousands of nodes. Ideally I would like to get either a random
set of those nodes,
failing that I would be happy with the the first N nodes.

You can also create an extensions that you call instead the normal rest-call.
So you can track of the last 10 of each in the extension.
Another possibility would just be a filter in front of the create - node and
create - relationship calls and keep the information accessable from the filter.

Thanks mattias for your reply. If I keep a linked list on the webserver for
the last created nodes I have a problem when I add a second server. I have
to keep the server synchronized. I wanna avoid keeping db-data on a
webserver
BTW: Im using the neo4j REST server.

Paul,
thanks for the info! I am down to the same, BerkeleyDB or JDBM.
Currently I am trying to get one of the BDB team to config the index
with me, so I can have some real impression of the performance (I am
just not able to tweak things right)
Meanwhile - is there anyone out there with a good kno
Bård,
Great to hear you're evaluating us for your solution.
I have a couple of questions. First, how much RAM do you have in the
machine, and how much heap are you allocating for the Java process? Peter's
question about running it multiple times is also very relevant.
Secondly, I'd like to under
Bård,
have you tried running the test multiple times? Given the amount of data,
neo4j should be able to serve this entirely from memory after a couple of
runs, so you should get fast numbers with repeated

Hi!
First really good work you are doing on the Neo4J project! Really
appreciate the good level of documentation as well!
Currently I'm running a POC for validating if we can use Graph and
Neo4J when we want to filter/ACL user-access to resources.
Our concept is much like your example here
http:/
Oh, OK, thanks for the clarification.
In the meantime I played with the propstat tool and shows in my case 50%
reduction in DB size (and will probably show a lot in performance). Very
promising ... ;-)

Hi Tobias,
I tried to use ShortStringEncoding.java, however it seems to refer to a
class called ShortString, which is not available in github:

Could you also please provide it?

Just what I thought
Hi,
I don't want to bother anyone but could you provide us with further
information about this ?
