Hi,
You can try to create intermediary nodes that aggregate certain kinds of
relationships, i.e. create a abstraction on top of them. This is also used for
write heavy scenarios e.g. activity streams with super-nodes which are
connected to millions of others - you just introduce a second round
If you're only returning nodes on depth=X (let's say X=4) and want to filter
relationships all along the way then maybe I'd use something along the lines
of:
prune evaluator: { language: javascript, body:
position.lastRelationship().getProperty(\userGroupId\,0) == 111; }
return filter:

Hi,
we are no longer using svn, we moved to github a while ago.
You can find the code located in repositories of this account:

With regard to the index, you can have multiple indexes, for large indexes
splitting them
up into domain driven parts should speed them up as
Could you start by verifying it is not GC related. Turn on verbose GC
and see if larger transactions trigger GC pause times.
Another possible cause could be that the relationship store file has
grown so configuration needs to be tweaked. The OS may be flushing
pages to disk when it should not.

I was wondering how can Neo4j projects be added to delicious Neo4j's

Interesting,
Could you write a test scenario that shows this? Would be very helpful in
tracking down why this is. I don't think there is much magic going on beside

To get the exact number you still have to count nodes/relationships.
getNumberOfIdsInUse includes Id slots waiting to get reused. So the
number you get may be higher than the actual number of
nodes/relationships in the database.
