Johan,
The plan of using "common" architectures is a great idea and will fix
the issues on porting and maintaining neo4j to .NET/Mono (please
remember that, as contributor to Mono, I'm attached more to this
framework than to Microsoft's one and I always seek for the full
compatibility with it).

Hi Tobias, thanks for the answers. I think you answers my questions
well. Please see the inline comment.

Hi,
As you may or may not know, the Neo4j kernel is heavily optimized for
reads and transactional updates, which in a typical transactional
system probably constitute 95+% of the operations. So far, we haven't
focused on raw batch insert velocity, since that's typically a
one-time operation that y
Hi all,
Johan just created a new ticket about integration with an external
transaction manager in for example a Spring environment. If anyone
here feels knowledgeable about Spring, feel free to chip in either in
this thread or as a comment in the ticket:

So I know I'm just missing something very basic here, but lets say I have 3
nodes representing users. The users have first name, last name, and email
properties. Now say I have 2 million users.
How do I efficiently implement findUserByEmail ?

Hi Matthias,
Great if you want to contribute!
Currently there exist no good external documentation on Neo4j
internals. This has been requested before and I hope we can put
together a document of that type soon (but very low on bandwidth right
now).

Hi Solomon,
Well, they are questions typically asked by newbies, but they are still very
good questions.

Well, that was easy :) Thanks!

Hi,
I was playing around with Neo when I ran into a problem. I made the
example as simple as I could, but still encountered the same problem:
public static void main(String[] args) {
NeoService neo = new EmbeddedNeo("var/neo");
IndexService index = new N
Hi all,
I just started looking into neo4j. Forgive me if these are newbie
questions.

(or probably I just haven't find it)
So I assume we should do getRelationships() and iterate through the
result?
Also, there is no API t

I would be interested to know how neo4j works on AppEngine, too. :)
Since Appengine does not offer file system, sounds like one has to map neo4j
data to GAE datastore.
