i found a page that link a lot of graph visualisation tools :

Friendly greetings !
i wish to display very large graph. ( hundreds of thousands of node,
or many millions of node if possible).
- graphviz probably won't do it.
- my processing app is 100% sure to explode
i found that, but didn't tried it yet :

i quickly hacked an app to populate the neo4j database with the
collatz conjecture graph.
here it is http://github.com/ker2x/Collatz4Neo/blob/master/collatz4neo.java
and the code is ugly, but it just works(c)(r)(tm)
now the problem is to find a way to graph millions of nodes. :/

Cool, I'm going to take a look. Thanks Niels.

Github project is up and running:
http://github.com/NielsHoogeveen/Scala-Neo4j-utils
For now it contains only one file with my first attempt writing a traverser in
Scala.
Scala version 2.8 is required.
Kind regards,

Hi Marko,
While I am not claiming that a traverser in Scala would be as powerful as
Gremlin, the combination of for comprehensions and traversals allows for a
concise formulation of working with graphs in Neo4J.
In my previous post I already mentioned the use of for comprehensions which
allow
Still,
very cool, and processing rocks!

If the system crashes Neo4j will begin the next startup with a recovery
phase.
During the recovery phase the logical log will be replayed. This reapplies
all committed transactions, bringing Neo4j back to the state it was in
before the crash.

Thanks for the info.
That triggers more questions, of course.
So what happens if the system crashes before the log is rotated? Will all
of the transactions in the log be rolled back (even if they have already
been committed)? Or will they be "flushed" on startup?

I don't have a github project yet. The code is still in a non-distributable
stage (trial and error snippets, no test code), but hopefully in a couple of
days I will be able to put it out.

As you say, a meta model validator is something that would sit nicely on top
of the event framework. And the plans for such a component is to not work on
it before the event framework is in place. Regarding the timeline for the
event framework it looks like we could have a first version in the
repo
If these numbers don't need to be declared ahead of time, but instead you
can let them be defined by Neo4j, you could use the relationship IDs for
this, then use GraphDatabaseService#getRelationshipById(id) to retrive them.
Then get the nodes from the relationship objects.

On Wed,
The logical log is rotated when it grows to 10M. When the log is rotated the
data is "flushed" to the respective stores.
What sizes are you seeing on the logical log? If its (much) larger than 10M,
and you haven't configured Neo4j to use a larger logical log, then we will
need to look into why tha
