I'm a bit confused about the traversal now. I'm not sure that I could do this
via REST API.
So basically, I have a basic graph like this
(ReferenceNode)---[rel:contains]---(A)---[rel:knows]---(B)
If I want to traverse from ReferenceNode to B, by return only B. Could I do
this via REST API? This
Hi,
What version of Neo4j are you running and are there any other error
messages written to console or to messages.log when you start up?
Do you have neo4j-lucene-index component on the classpath? The global
transaction log contains a transaction that included the Lucene data
source (branch id
It works! thanks a lot. :)

Nice,
let us know your feedback. I hope the Gremlin extension makes it soon into
the main distro, but we want to test it first a bit more. Thanks for
installing it!

Max, Stefan,
I added documentation about the built-in traversal support to the REST API
documentation,

am waiting for the build server to finish to push it out to
Vincent,
I think this is quite normal for your setup. Since you have not much memory,
and a lot of data, you are hitting cold nodes pretty often, especially when
the caches are full after a while. Then, it is a matter of how fast you can
access the disk. How big are your store files?
To improve
Hi there,
any solution to this or do we need to dig deeper here?

Hi,
I am trying to set up a scheduled backup for my neo4j database and I have
been unable to get the backup to run.
See below for the commands I am running (first to do a full backup and then
incremental).
The weird thing is that I was able to run the full backup, and incremental

Under high load, with multiple threads writing and reading simultaneously,
after a couple of hours, things start to melt down and we get:

Any thoughts?

Hey Rick,
Got any stacktrace/cause to go with that?
Thanks,
David

Hi,
How do I do something like this:
PathFinder finder = GraphAlgoFactory.shortestPath(new
OrderedByTypeExpander().add(DynamicRelationshipType.withName(knows)), 6);
...but where I don't care about the RelationshipType taken (and I don't want to
enumerate all the types I have as I have
Marko,
you could do an AllExpander(Direction.BOTH) or really any subclass of
Expander, http://api.neo4j.org/current/org/neo4j/graphdb/Expander.html
Does that help?

Hey,
Yea. Thats what I'm looking for, but it doesn't seem to be part of the API? .. ?
I can only find StandardExpander (abstract) and OrderedByTypeExpander.
Thoughts?, -- IM me if you wish.
Marko.

I'm learning to use PatternRelationship to look for a pattern of
relationships in the dataset. I was wondering that is there any example? I
only found PatternNode.
Thanks a lot.
