Hello Michael, I glanced through plugin's source code, and spank me if
i'm wrong, but is the plugging limited to removing only 1k nodes at a
time?

Hello folks, i've been trying to prune based on number of outgoing
relationships, but so far i am stumped,
since org.neo4j.graphdb.Node interface doesn't expose any way to count
outgoing relationships. Traversal is for
tree visualisation, and i want to avoid creating too much of a
clutter, hence
In my opinion, the current syntax reminds me of SQL, which is a good
thing. All the newbies like me can easily wrap their head around the
concepts, without much problem. Since you can't do an actual
assignment in Cypher (please correct me if i am wrong), an equal sign
clearly means comparison
START n=node(119) MATCH n-[:CO_S]-m, n-[:CO_S]- t, m-[r:CO_S]- t
return m.w_id, t.w_id, r.sig, r.freq
took: 644ms (average of 100 runs after 10 warmups)
Can you try using shortestPath cypher function for m-t ?

Specifically what's bad about how they are handled is that to get any
relationship from a node they all have to be loaded once first into cache,
regardless of which type
Great, since my schema is a tree (1 incoming, up to hundred of
outcoming) i was worried about that.

Of course providing some more context would be poor too? How are
we supposed to know what's the problem?

Btw, inserting 600k nodes over REST with about 8 properties in batches
of 100 takes 20-30minutes for me. It's not awesomely fast, but it's
not slow either. What settings are affecting insertion speeds, Peter?

Does this problem occur with automatic node indexing?

It all depends on task at hand. Personally, i've had most success with
REST API, which allows you to define your own prune evaluators and
filters. With prune evaluators you an easily exclude nodes from
traversing, based on your rules. Although my graph is small (600k
nodes, 1.8M properties), i've
First off, thanks for py2neo. I think i found a bug that prevents from
using javascript filters when traversing over rest:

Instead of body, key is named name. Since you're on vacation i've
taken justice of sending you
No problem, on the other hand the name parameter is still valid,
since there are two named filters: all and all_but_start_node, and
whatever filters someone may add themselves.
I also have one issue with Node class, i really like the way original
JPype bindings work - i.e. i can use
No need to, i submitted a pull request with that change. I will also
submit my proposed index syntax changes. I'm no good at git, so i may
or may not screw this up.
As far as changes you wrote about, i think we should move it to one
method, and rely on arguments supplied by user to know which
What is your memory mapped files configuration? Are you sure you
aren't running out of memory?

It is worth a try. Remember that on linux, memory mapped files are
allocated outside of JVM heap, so when calculating total memory usage
add whatever you configured to the JVM heap.
Database size on hdd doesn't mean much, mine is 80megs, but when all
