Hi,
I've two types of nodes *Gender* and *Activity*
Gender will be male or female
Activity node will contain fields *activity* and *count*
where there will be *n no of activity* fields with *n no of counts*
For eg:
activity = Activity1
count = Count1
activity = Activity1
count = Count2
.

I have installed Neo4j 2.1.1 in the directory of C:\Program Files\Neo4j
Community in windows 8 32 bit machine. It creates default.graphdb by
default C:\Users\Jeyatharshini\Documents\Neo4j directory. I copied it in
the same directory and rename as routeFinder.graphdb.. I browsed through
Neo4j
Should I add index to view graph in web interface?

Most probably these are changes that have not yet propagated to all

You probably want to look into sticky routing if you access data that
you've just written to the current target machine.

You can access the database directly either from java or the server, not
from both at the same time.
Access to the database files is exclusive.
There are two more options:
1. Use the Neo4j-JDBC driver:
https://github.com/neo4j-contrib/neo4j-jdbc#minimum-viable-snippet
2. Write your Java Code
You have to flush the index before reading from it after writing.
For fast operations I'd recommend to use an in-memory structure though like
a Map to keep the node-ids you created for your URIs quickly available.

There are a few things to try:
- Improve performance of Neo4j in general through cache/mmap
configurations.

- Use the alternative REST API for indexing and search for nodes. This
might be slightly faster. Instead of
I also tried just remove the label per node (i.e.,
node.removeLabel(label_name)), later query using
the same label won't work but I can still see the labels in the web

Not sure if this means they still exists or not.

So I have a Label *Title* with the property *title*.
With the Noe4j properties I set an index on it with neo4j.properties and
*node_keys_indexable=title*.
So I have loaded* 1 Mio* nodes of Title.
And did the query:
*start n=node:node_auto_index('title:*CAPTIVE*')return n;*
That give me *2*

Hi Sebastian,
I'm not sure I understand your model.
The relationships between stations are one seat of segments of the same
train-trip ?
I wonder why you didn't model the train with it's wagons and seats as nodes
and then connect the seat nodes with a RESERVED_FROM releationship to the
stations
I tried to put it together but have no realistic data to model it in a
graph gist.
Would be fun to load actual train stations, routes and reseverations with
LOAD CSV into a graphgist though.

Hi,
We have a Neo4J 2.1.3 database and we have a uniqueness constraint that was
created as follows:
CREATE CONSTRAINT ON (segment:SEGMENT) ASSERT segment.segmentId IS UNIQUE
When we test this from the browser, it works fine in detecting violations,
e.g:
CREATE (n:SEGMENT {name : duplicate,
To assure uniqueness across multiple threads and a cluster (with
appropriate locks, please use MERGE)
MERGE (n:SEGMENT {segmentId : 110484}) ON CREATE SET n.name = name , ;

We're already writing to the master.
What do you mean by with appropriate locks? We're using Cypher over REST
hitting the transactional endpoints as documented at:
http://docs.neo4j.org/chunked/stable/rest-api-transactional.html
I don't see anything documented there to allow obtaining of any
MERGE is the only cypher operation that guarantees uniqueness and also
takes the necessary machine- and cluster-wide locks to assure that.
