I'm doing that, and it works fine.

Hi,
I cannot figure out how my application logic can reify links with
other neo4j databases located on different distributed servers?
hence , how can i make the traversals and graph algorithms transparent
to the location of the different databases ?

I have another question, I changed the pom.xml file as you suggested already.
When I run mvn test in the command line it runs perfectly, but when I use
IntelliJ with Maven plugin it throws that error. I checked that my IntelliJ
included the latest version of shell and neo4j. Anything I'm missing he
Craig or anyone who can answer this: what does the wkb value represent here.
I know its the well known bytes, but how do I get back to wkt? I thought it
was a byte array, but I can't seem to get my original values back. Form the
values in the test case I have:

Todd,
did the edit work out? Also, we should clean up that page and not
mention all the other options, just the current bindings.
WDYT?

Hi, I have a question about sessions in Neo4j. I'm working with the embedded
Java (not as a server) and I can load my data and query it between transactions
without trouble. My question is whether/how it's possible to shut down my
database at the end of a session and then access it in a new sess
It seems I was looking in the wrong place. There actually is a Btree
implementation that works on the basis of nodes instead of properties. I will
test this implementation to see if it has the performance characteristics we
are looking for.

Hi there,
Haven't tried it, but I would guess that you have to use the same version of
things. Use 1.4.M05 of neo4j-shell, or 1.4-SNAPSHOT of neo4j, and you should
be good to go.

Hi Craig,
Thanks so much for this reply. It is very insightful. Is it possible for me
to implement the LineString geometries and lookups using REST?
Many thanks!

I delved a bit deeper into the BTree implementation in graph-collections and
learned that it is essentially a tree based version of a property container. It
is not possible to add nodes to the BTree, only primitive values. The graph
based Timeline uses the BTree to store some entries, but does
No but you could group them on some simple function (like the last n digits).
Perhaps just the last 5 digits then you have 10k nodes with 35k index entries
each.
(And you can of course index those nodes with those 5 last digits so you can
quickly retrieve them) (for adding to the index - or you
You have a few options here:
* paging is right now only supported in the REST API for traversals the other
request types will get it in 1.5 (so you could use the paging functionality for
your traverser, don't know if Max supports that already in neography)
* you could use either the cypher

Does it make more sense to have each hash index point to its own node
... so I end up having more then 350.000.000 of nodes. So does this
will help?
the ruby crash when i request all the page with parsed = false
using directly the REST interface with CURL : the result is a huge
json with ~10.000 nodes
is there a way to limit the result size, like a SQL "SELECT * from
node where parsed == 'true' limit 100;" ?
i tried using a traverser instead o
The Expander solution seems to be working well (thanks Michael) & the I am
sure proposed B/RTree solutions could be even better.
But the big question is to have this supernode/relationship indexing
functionality integrated into neo4j in a coherent (perhaps plugable) way,
such that can be utilized
Can you call the index REST request manually and see what it returns?
see here
http://components.neo4j.org/neo4j-server/snapshot/rest.html#Index_search_-_Exact_keyvalue_lookup
curl -H Accept:application/json
http://localhost:7474/db/data/index/node/my_nodes/the_key/the_value%20with%20space

After a few run (and more and more and more page to crawl) it seems
that the result returned by the index is too big :

stack level too deep (SystemStackError)
Any idea ? workaround ?
thank you

Hi,
I'm very interested your HA architecture and wonder if possible to
extend the zookeeper features in order to cover the jobs for an app
server.
So that, we can have much simply architecture. The jobs for app
server includes user authentication, encryption service for
communication..etc.

I used Base64.encode64 instead ! it still didn't worked.
So i used Base64.encode64 and get_node_index instead of

thank you for your help.
as you probably noticed i'm not good with ruby (i'm a sysadmin ^^)
i tried using URI.encode but it doesn't works as expected.
irb(main):001:0> require 'uri'
=> true
irb(main):002:0> puts URI.escape("http://www.over.blog.com/";)
http://www.over.blog.com/
=> nil
irb(main):0
i would be interested in knowing about anyone who has combined neo4j
graph db with other dbs like Cassandra ,orient db what is an optimal
configuration to do so?
any other configurations for polyglot persistence to achieve high
scalability and massive parallelism?
