Anybody care to share a strategy or base classes for unit testing
operations in the graph?

Tim,
this is a common misconception - you want warm caches, but maven or
any other build system is testing cold since everything is started in
a fresh JVM.
I think here there might be an option to introduce some "warmup"
switch to Neo4j. In that case, Neo4j would try to fit the graph into
memory b
Awesome, thanks!

Not that this solves your issue but...
1. If it is a webapp you can use a filter that wraps the request
around a transaction try catch finally... then your code would be
transaction free (mostly)
2. If you use a Spring service you can use @Transational or AOP
interceptors to annotate operations th
I know this has come up a couple of times and that transactions are
being worked on it Traversers, but I just can't get my head around how
people use neo4j transactions in general. When I started writing
neo4j code a couple days ago, I was amazed at two things: 1) how
efficient and fast it
AFAIK this behavior is specific to lucene as lucene indexes everything
as Strings following their natural order.

Hi Neo4j users,
I am confused with LuceneFulltextQueryIndexService.
For integer,
IndexService index = new LuceneFulltextQueryIndexServic
e( neo );
index.index( myNode1, "someKey", 1 );
index.index( myNode2, "someKey", 2 );
index.index( myNode3, "someKey", 12 );
index.index( myNode4, "someKey", 2
Thanks for your reply.
Since I am trying to search a range of integer, index.getNodes( "someKey",
"[0 TO 1]" ) will returns node with "somekey" value such as 1, 11, 111
supposing having 1, 11, 111, but I only want returning 1 exactly. I know one
of solution is using padding scheme to solve the pro
Thank you everyone -i really appreciate all your help ;)

This time it was completely my fault -i'd been benchmarking on a cold

scala and scalac are shell script (or batch on windows).
On my scala version, the end of the script look
Hi, Tim.
Here's a section on the various memory tuning options for Neo.

In terms of setting Java VM parameters, I know how to do it for a Java app
or application server, but not for Scala. ;-)
Anyone?

Tim,
I think the structure is quite normal, would be good to see the code,
you could send it to me off-list. That way I get an impression on both
the querying code, the dataset size and maybe test-run it.

hi Peter
Thanks for the rapid response (one of the reasons I really like the Neo crowd)
ok - structure
Node: Event (for the start of a session)
So the first time a user loads a page then creating a new
NodeEvent
Node: EventItem
Every time the user generates a new
Tim,
yes, since your loading evidently is working normally, a look at your
graph layout and query code would be great to have any opinion on what
might be wrong/not optimal.

hey :)
ok - I'm trying to build a "web-analytics" program using Neo4j
in a very similar manner to http://wiki.neo4j.org/content/Site_Usage_Analytics
I'm using Scala (and whilst eventually there will be a REST API - at the moment
everything is within Scala)
The loading of data is blisteringly fas
We will probably cruft together some type of neo viewer/editor in flex (java
back end) in the next few months. It will rely on traversing from the root
node, most likely.

I have an old framework for serving neo graphs as web pages which I
was deploying using tomcat. It allows you to describe a template for
rendering a neo node and some options around mapping nodes to url. It
is part of the snosled project on sourceforge which has not been
progressing at the moment :
Mmmm, there is, in fact, a neo4j grails plugin :)
