Hi, I've just started looking at Neo4j and I'm quite intrigued. However,
the cognitive dissonance that I've grown so used to in modeling storage is
proving to be a bit difficult to let go at this early stage :)
I was hoping that if someone could help me through an example I would be
able to grok
You don't need to consult every single player after updating the
scores — only the ones that are already on the leader board. So the
time to make an update should be relatively constant. The maximum
number of updates will be relative to the deepest chain of
introductions in the pyramid. I d
I'm away from the computer in question now, but I did have that
directory, and it did contain files. I've also tried installing to a
directory in my home directory, i.e. no sudo involved, and everything
seemed to install just fine. But still no backend when actually
running.
Is there a list of the
Hi Ryan,
It's nice to see that interest in using Neo4j with Python is picking up :)
Traversers in Neo4j return the (returnable) nodes they visit as they
traverse the graph. It sounds to me that you are more interested in the
relationships. I'm working on changing the traversal subsystem, that wil

Hi,
I have a large graph and I am trying to extract the list of edges that
correspond to some relationship "foo", node A -> node B.
I cannot figure out how to do this. I have tried using a traversal
class, but I am not having any luck.

It looks very strange. Which version of Jython are you using?

Thanks for your answer, it's a pity.
I don't have enough time to develop this feature myself; it's not a high
priority and I don't have any experience of developing eclipse components.
I'd be happy to offer a very small bounty (~$50) if somebody else is
interested in implementing this as a featur
If the total number of players scores changed was a relatively small part of
the list, then re-linking those on each change might still be efficient, but
you indicate that the number might be high, then Rick's b-tree approach
works better. In my opinion you have two options:
- Lucene - you can
Yes, this will work. The delete operation is really just a "mark for
removal" operation, they still be reachable until the transaction is
finished(), this is to enable things exactly like the scenario you are
describing.

Miguel,
from your code, it seems that you are trying to read up a lot of
relationships from the nodespace into RAM by populating the

I cannot test the code, but you should probably check the size of that
construct. Neo4j itself should degrade performance gracefully if th
The create=True parameter is per session at the moment, this is a known
issue, and is going to be resolved at some point. It depends on support from
the underlying subsystem that is not implemented yet.

Thanks for answering! Linked list... My spontaneous feeling is that then
I'll have to sort every time the scores change, right? And that operations
would probably take more and more time depending on the number of players..?
But the fetching of the leaderboard would be dead fast every time!
