Nabeel,
you are right, this is not going to work. I am prepared to take out
the cost evaluation again since I don't want to have non-working code
in there, and have no time to figure this out right now.
Is that ok with you, or would you like to figure out a better place to
put the cost evaluation,
Hi,
This sounds like a scala wrapper issue.
Short lived write transactions together with long lived reads should
be no problem. By default no locks are taken during reads instead each
read operation behaves as if it took a snapshot of the graph
(committed state) at point of invocation. So to answ
Well yes, compass provides search capabilities on top of a large number of
other projects (Hibernate, JPA, XML, JSON etc) and also provides integration
with a number of distributed cache implementations. As such the dependencies
are required to build compass,
However, if you aren't using those spe
Hi:
The corner stone of this data will be an identity to which we will want to
associate information about that identity. The problem is sometimes we want to
see what is related to the identity and other times we want to see what
identities are related to some identity attribute, kind of Linked
I took a quick look at Compass, and it looked really interesting and
promising, until I dl'd the distribution with dependencies - seems like
every single open source Java project is included as a dependency/JAR
library... :(

Actually I'm calling the getSingleNode, thus I have no access on the

Hi:
Potentially stupid questions follow: In looking at how to add sharding
to Neo4j, I was wondering if it made any sense to put Neo4j on top of
Cassandra or maybe a distributed BTree+ system? I love the relationship
modeling in Neo4j but I need the scalability of sharding; preferable not

Yeah, it worked pretty well. I'd used compass in a more normal situation
(RDMBS and Hibernate) and my experience with it took me that direction. It's
a very nice project.
I'll dig the code out and look, but I have a feeling I could be embarrassed
by it - it was very much a prototype.

Ah, do you make sure you call IndexHits#close() on your results from
getNodes(), alternatively iterating over the whole result (in which
case it's automatically closed)?

Hi all
While populating a Neo graph, I got the attached exception
(org.apache.lucene.index.MergePolicy$MergeException. See file for
details: I replaced a local path with [some-local-path]).
My setup is like this: I want to benchmark Neo4j for some operations,
amongst which is graph loading.
So
hi guys and girls
I'm currently running Neo as a web-service - exposed through a SCALA
based REST API
The web service essentially does two tasks
a) transactional - allowing the creation and modification of nodes
- these require read write locks but each one is relatively short in
duration
b)
Well noticed... Peter, will you have a look?

Hi all
Thanks Peter for adding a cost limit option to the Dijkstra algorithm in the
graph algo package. However for some reason I could not make it to work as I
expected.
I see you have added some tests in FindPathTest#testMaxCost method (which is
given below):
public void testMaxCost()
Yep very nice, maybe we could see if it could be a good "core"
component of neo4j. So if someone feels like writing a
CompassIndexService and see how it works out it's totally fine by me
:)
