I need to store graph data using Batchinserter efficiently and need to make
sure that it only stores unique nodes. So for this purpose we are using
batchinserter and indexing. But for some strange reasons indexer is not
working properly and does not reloads previous indexes on application

Hi,
I am using neo4j 1.9.7,SDN 2.2.0.RELEASE and haproxy 1.4.24 to run the
environment. I have 6 server,1 master and 5 slavers .Write to the all
server.
Now I always get these exception:
org.springframework.dao.DataRetrievalFailureException: 3189664; nested
exception is org.neo4j.graphdb.NotF
Thanks again for the reply.
Unfortunately that single page is a bit too simplistic. We have a
relatively complex object model (10 different node types, 20 different
relationship types) which will probably contain easily up to 100k nodes.

Hi Nirali,
Afaik there is a new version called blueprints-neo4j2-2.5.0 for Neo4j 2.x,
which should be up to date.
Cheers, Michael

You can just expose a simple cypher endpoint from your application, that
you then connect to from a single page javascript app like this:
jexp.github.io/cy2neo
An example for that endpoint would either be CypherService (where you only
have to adapt the jersey changes) or the transactional cypher e

Thanks for the reply. I should have included that information...
We have maven dependencies on neo4j-enterprise, neo4j-ha, neo4j-cypher and

We also have an additional dependency to deploy the static-web files of

Hi Andrew,
if you run Neo4j embedded you don't have Jersey dependencies, the kernel
doesn't have any. ??
You can extend the server with server extensions that are exposed via
Jersey Resources but then you shouldn't have any different Jersey deps.
Perhaps you can explain your application architec
The service locator mechanism can't find any CacheProviders, so when it tries
to set the cache at index 0 up as the default fall-back implementation in case
no configuration is provided, it fails. This is strange because the database
kernel comes with a couple of CacheProvider implementations.

Hi all,
I have neo4j imported into my eclipse and build my server script. But when
I try to export it into jar file, some errors are constantly showing and I
have no idea why that happens. My original server script just run fine. The
error comes from the following instructions:

Hi,
I see that 'blueprints-neo4j-graph-2.5.0' is the latest released version to
use tinkerpop blueprints api with neo4j graph which is version 1.9.6.
A few questions on this:
1. I understand that this neo4j instance will be an embedded database with
community version. Is that right? If so, how
Hello,
I know this is an older line of discussion, but would it then be possible
to tie the indexes and constraints to relationship labels in a future
release? To speed up finding properties of a node in relation to another
specific node I store them as a properties of the relationship. However

I have noticed that the 'undefined' problem occurs when the directory
storing the database does not have the correct write permissions or
administrative rights, irrespective of the environment of operation. If you
are on a unix based system, the database directory must have write

Hi Guys,
I'm not sure if this issue was sorted but if it helps I found that this
error happens to me when I use a 32 bit JVM and not when I use a 64 bit JVM
of the same version. There's still some undeterministic behavior
associated with this because it'll also only happen when I run 2 junit t
We have no such plans. Neo4j talk to storage in terms of pages, which is
sensible even on SSDs and copy-on-write file systems. We do want to reduce the
space puff-up on crashes, though, but I don't know what priority that has.

Hi Chris,
I know preallocating files is useful to improve sequential read speed

Hello,
We are running neo4j embedded within our application and have the need to
include a module which depends on Jersey 2.9 / JAX-RS2.0
Neo4j-server is running Jersey 1.9.
As you may know. v1 and v2 of JAX-RS API have fundamental differences that
do not allow them to execute within the sam
Does anybody have any idea about this?
