Hi there!
I was wondering if it was possible to add multiple key and value pairs
to the Neo4j via REST API? Something like posting a JSON array of node
URLs with keys and values to the index root.
POST /index/node/my_nodes
{
"http://neo:7474/db/data/node/52"; : {"key1" : "value1", "key2" : "val
Jose,
how did this work out, did you get into the Wiki?

Hi there,
why do you need that? If you want to load a file from within a plugin
in order to e.g. initialize something or load data, I would suggest to
use URIs (which can point to files on the filesystem, absolute or
relative) and let then your plugin load that file form the URI.
Is it a specific
I'm looking forward to it!

I think you could implement this using RELATIONSHIP_GLOBAL uniqueness, like
(from the top of my head):
Traversal.description().uniqueness( Uniqueness.RELATIONSHIP_GLOBAL )
.evaluator(new Evaluator() {
public Evaluation(Path path) {
return path.length() > 0 && endNod
Great, thanks! We'll do a test build using it and report back results.

Subject: Re: [Neo4j] LuceneTimel
Looking at the implementation it's bascially just one-liners wrapping a
lucene-backed Index so either way it's easy to implement/change API-wise on
your own if it would change in ways you wouldn't like. But I think it will
stick around and hopefully not change all that much.

What do you mean by "your own index"? Using index for relationships is fast

Thanks, Mattias.
I suppose I should ask the question then as to whether or not this feature is
'experimental' and might be changed or removed in a future release?

Great!
You could look at
https://github.com/neo4j/graphdb/blob/master/lucene-index/src/test/java/org/neo4j/index/timeline/TestTimeline.javaI
don't think there are public examples of it since it's a rather new
(and
rather small) implementation.

Hi all,
I would like to detect all cycles in a traversal.
I know the traversal framework has cycle avoidance built-in, but there
doesn't seem to be an API for cycle detection!
Has anyone already implemented a cycle detector for traversals?
Thanks in advance,
Wouter

Yes , This the answer I want :) As You said:
"you can use the index to get the nodes as soon as you have added them in the
same tx other tx get the nodes after commit"
The real-time mean I add some nodes or relations in the index, I will get it as
soon as In other tx.
I have see some docu

The embedded version of neo4j typically works *better* when there are multiple

Hi folks,
"Embedded" simply means running in your choice of JVM process. Most embedded
Neo4j instances aren't embedded in the hardware sense of embedded systems,
they're usually server applications that happen to use Neo4j as their database
(sensible choice!).
So imagine I have a Web app set t
If I've well understood, you can have only one connection to the database
for each VM. So, the service must be encapsulated in a singleton I guess.
How many transactions each connection can handle ?
