Michael,
What do you mean by filter on the relationship type? I was under the
impression that all relationships for a node are in the same linked list
and there's no fast way to filter for the relationship type without
traversing through the whole linked list.

Hi,
I am using neo4j 1.9.5 and the core java neo4j api with server un managed

Please check the import.sh script
at the top it says HEAP=4G
change that to HEAP=20G
Other than that it still can be a disk issue, do you have an SSD or a spinning
disk?
Perhaps you can have a look at the blog post I mentioned.

Q.how do you run it? Do you provide enough heap to the importer? I.e. 20GB ?
A.i didnt unterstand exactly but i am running it import.sh utility. I am
new in linux so i dont know how to provide heap to the importer? could you
please tell me how?
Q. So you have 110M Animals and 460M rels and 42M H
The config is only read once at startup.
You have to restart the db to change the config (afaik).

I have suffered from this issue and we have a few workarounds currently
that fit our data model.
I do not recommend indexing as a solution. We attempted to do this, and it
lead to GC problems as Lucene was create a lot of trash, so my high
performance query was spending a lot of time doing GC.
Hi there, I'm using Spring Data Neo4j 3.0.0.M1, along with Neo4j 2.0.0-RC1.
My issue is with converting my complex Entity to a flat node object using
repositories. I certainly understand that I might want to model a bit
differently for Neo4j - but was really hoping that SDN provided some kind

I have a bash file that is doing various embedded mode imports. What
happens if I change the configs during that process (namely the cache file
sizes). Thanks!

The best way would be to write an unmanaged extension and deploy it into the
server:

In my use case, one component is written in Ruby and access the Neo4j db
via its REST interface. Another component, written in Java, does scheduled

Hi Michael
Thanks for the response. See the first post in this thread for what I mean
by "it doesn't work." Basically, it comes down to label matching not
working at run time. There were no errors at import time and everything
completed successfully. I also don't believe that I had any quirks in m
What exactly "didn't work" ? did you see any error messages?
Any chance that you had some quirks in the input data? Like newlines in fields?
Could you re-try it? I think when you posted your question initially neither
Neo4j 2.0.0 final was released nor the batch-importer updated to that version.
Hi Michael
My apologies for the late reply, I have been on vacation. I did use the 2.0
release of batch-import. I've attached some sample data. Also, as I said in
a previous post: labels worked on a small file (hundred of nodes) but not
on a large file 20 million+ nodes.

Hi Luanne,
Following query is working now but sometimes it does not work may be some
server issue.
START m=node(2), n = node(*)
OPTIONAL MATCH p=(m)-[r:FOLLOWED_BY|CREATED_BY|FOLLOW_PENDING]->(n)
WITH r, n WHERE has(n.timeBoardName)
AND n.timeBoardName =~ "(?i)exp.*"
RETURN r, n;

Hi Michael,
So you mean I have to use SDN 3.0.0.M1 ?
With 2.3.3, I have the following problem :
java.lang.IncompatibleClassChangeError: class
org.springframework.core.type.classreading.ClassMetadataReadingVisitor has
interface org.springframework.asm.ClassVisitor as super class
Thanks,
Grégoi
SDN 3.0 should be compatible with Spring 4.0
What was the issue with SDN 2.3.3 and Spring Framework 4.0 again?

Hi,
Spring Data Neo4j 2.3.3 has dependencies for Spring 3.1.4. Should we wait
for a new version of Spring Data Neo4j or is it possible to use Spring
Framework 4.0.0.RELEASE?
Thanks,

You would model those infected-by information relationships between the nodes,
not as property containing a number.
Then you can use variable length paths to do long and also circular matches in
the graph.
MATCH p=(n:Person {name:"Mina"})-[:INFECTED_BY*]->(m)
RETURN path,m

Jason,
The release is afaik planned either for some time in Q2 2014.
actually the workarounds are not so difficult.
The easiest one is to add a separate node which holds the 1M relationships. So
your actual node has just 1+100, the 100 that you mentioned of type 2 and the
one to the separate n
i want to get recursive query in neo4j with cypher.
in dataset ,nodes has property "whom" that shows the node get infected by
whom
(for exmaple node[1] is infected by node[10].-> node(1).whom= 10 )
i want to search the graph recurively from the node[1] to node [10] and
recursively so on to reach
27 matches
