Reading it again, I think this is the most likely culprit, especially if you
only have 7500 items. Try everything in a single transaction.

I can't give too much help on this unfortunately, but as far as possibility 1)
goes, my database contains around 8 million nodes, and I traverse them in about
15 seconds for retrievals. It's 2.8GB on disk, and the machine has 4GB of RAM.
I
allocate a 1GB heap to the JDK.

Hi,
Is it possible to mark a transaction as being read-only? It's taking a while
for
my transaction to shut down, even though there are no writes to commit.
Thanks,

7;m basically removing duplicate nodes based on
an
attribute, so I need to build an in-memory look-up table to recognise whether
I've seen a particular node before). I'll change the traverser like you suggest
and see if this improves.
Thanks

Hi Marko,
This looks great. But it's been so long since I did set theory or any proper
maths that I can't read the symbols any more. In fact, I have had the same
problem with every book on graph theory I've picked up recently.
The slides would be clearer for me if each expression was paraphrase

Hi,
I need to be able to retrieve nodes whose timestamps are greater than a
particular time.
I've been trying to use a TimelineIndex, but didn't realise that it was a
persistent structure - I've written code that will create a new Timeline each
time my application is instantiated, and it's com
imeline-index available in your neo4j-version?
It appears to give you just what you want:

Hi,
Each of my nodes has a 'time' property associated with it. Is there any way I
can retrieve all nodes where 'time' is greater than a specific value? I can't
see how to do this with a full-text index...

Where do you set the 'count' property?

Hi,
I'm traversing a Node set, calling getProperty on each node. However, the value
returned is always '1', even if this isn't the value of the property. I've
confirmed in neoclipse that one specific node has a 'count' property of 2, but
when I debug my code, the value '1' is returned for that
ationships, creating an Array of relationships. Sort the array by
your visit order property and you have the route cache. Step backwards
through the route creating the route relationships as described before.
Cheers, Craig

Hi Craig, thanks for your answer.
What's your approach that would allow me to specify the destination node at
analysis time? I'd like to retain the flexibility to do this too.
Thanks

Hi,
Yes, it's to avoid having to pass around both the batch inserter and the index.
A lot of other APIs provide access to underlying data structures.
