hi . i am using Neo4j 2.0.3 version.
i am working on a DB where we need to track user path based on some fixed
location.
like which location is most visited.
so what i am doing :
1. Each user has unique node.
2. Each location has unique node.
when user traverse a location then which is
Depends on your use-case, what do you want to do with the data? If you just
want to store the fact that the user was there a relationship is good
enough. If the actual visit is a really important concept in your domain
that also other things are linked to and which has its own identity then a
node
From data i want to calculate :
1. which location is most visited by user.
2. which path is most visited by users
3. also need track a user : path or location visited by him.
4. Also need to track how muck time a user spent on a location

Hi, after publishing this
graphgist http://gist.neo4j.org/?05d92f567adbe971afc5 , Michael suggested
to change the pattern and providing a profile.
This is the result:
The query is
{
query : match
(j:jurt)-[:HAS_TERM]-()-[:BT*0..]-(t:term)-[:BT*0..1]-(t2:term
{name:{termname}}) return
Dump!
All is really stopped without correct working of this... QQ

Not sure how py2neo does it internally with these statements, but I think
you still have to commit your query.
According to the docs it commits immediately, but perhaps there is a bug,
so that the node goes away after tx-timeout?
Could you produce an http log of the http requests between your
Hi All,
I have 3 type of nodes joined with relationship and each node have
heavy set of properties , the total number of nodes are around 20 million
with node store size around 250 MB and property store of size 8GB , however
my queries at this volume are not performing at all ,

I'm sorry, but I cant understand what logs you mean?
It's web application.
In neo4j folder i can't see any requests log. Where to find it? o-o
Thank you.

Michael's guess is correct, there is a bug in the *Session.execute* method:
https://github.com/nigelsmall/py2neo/blob/feature/bindable/py2neo/cypher.py#L153
Here, the call should be made to *commit* instead of *execute*.
I suggest that you use the longer form of *append* and *commit* until this

There are language drivers available for most major programming languages
(mine is the Python one):

In terms of choosing a language, Java wins if you are looking for raw
performance - although that is becoming less of an issue as Cypher
improves. It can also
Your most likely I/O bound instead of CPU bound. If you haven't tried
already, since you are only doing reads you might be able to omit the
tx.success() call inside the transaction.
Another thing you can try is doing more inside of one transaction
(batching), as well as trying the
That's why I suggested UNION.
So the two individual queries take 14s? Still way too long.

Sounds not too bad. Did you do that on Windows or Linux/Mac ?
Probably more memory or a faster would make it faster.
Do you have the csv-files to share somewhere?
Thanks a lot

Hello,
The only info I could find at Neo4J site about Java REST API is this:

From this info it is not clear at all if Java REST API provides any more or
less high-level functions to parse results that Cypher query
What is it that you actually want to achieve?

I need Java REST API to query remote server with Cypher. I hope to find
some Java libs that will make working with queries like:

easier then just making a series of HTTP request and parsing JSON.
Please advise.

Even this case:

I'd love to hear official estimates.
