HI, thanks for replay.
Can you tell me when can i expect this.
I need to know whether to wait or look for own solutions.

Example: users following other users.
Is there any advantage/disadvantage to directly connecting users with
relationships, vs. indirectly connecting them via nodes?
E.g.
(:User) -[:FOLLOWS]- (:User)
vs.
(:User) -[:SOURCE_USER]- (:Follow) -[:TARGET_USER]- (:User)
The node obviously lends more
hi, one advantage of an extra hop that represents the event of one user
following the other can be the fact that you can now link that follow
node/event to a timeline graph node which allows for time based traversal
.. and see what happened at some point in time.. who followed who .. when
.. etc
actually i asked the same question in a somewhat different manner a few
weeks ago... i.e. to replace relations through intermediate nodes
representing the relation to allow for inclusion of the time based
dimension.. the question was if there is experiemce out there doing this
for bigegr graphs ..
Pros
- you can use the intermediate nodes to link other nodes to, instead of
providing nodeids as values of relationship properties
- it allows you to create a system to version networks
Cons
- longer paths, more complex queries
- managing the rels between the principal nodes is more complex,

hi, i use node array. i think it is fine now. but i have another question
here.
public static void main( String[] args )
{
final String DB_PATH = target/neo4j-hello-db;
GraphDatabaseService db = new
GraphDatabaseFactory().newEmbeddedDatabase(DB_PATH);

Michael, with execution_guard_enabled set, does it use a default? If so,
is it set by org.neo4j.server.webserver.limit.executiontime? Or something
else? Thanks.

Thanks guys. I'm totally aware of the modeling pros of nodes -- sorry I
didn't state that more clearly -- but I'm really wondering if there are any
*major* cons to removing the direct relationship.
Conceptually yes, more complex queries, but in practice, does it hurt
performance of simple
I guess having both unnecessarily complicates the model. I'd get rid of the
direct one, since apparently you need the intermediate node. You can always
recreate it on the basis of the rels through the intermediate node.
And eh... may I kindly suggest to rethink the title of your next post ;)
Yes, you're right re: title. =)

Hi, I'm running a large graph node. 265214 nodes and 420045 edges.
I'm using the traversal example from neo4j doc.
public String knowsTraverserforward( Node node )
{
String output = ;
// START SNIPPET: knowslikestraverser
for ( Path position : db.traversalDescription()

Hi All,
the same problem , i don't know how to resolve it...
I have a Dictionary that hold 2 kinds of objects ( Documents and there
words):
DictionaryDocument, ListConcept lista = new DictionaryDocument,
ListConcept()
i'am using neo4jClient , i read that it possible to make it with cypher
Tried to answer there.

In general probably too little, RAM if you only have 2G in total as OS,
FS-Caches and other services also take their share.
Depends also on what you're doing.
Perhaps you can share your graph.db/messages.log
