Hi Vipul,
Out of curiosity, what does process in this context mean?
As Rick alludes to, you'd have some component performing the simulation
using the domain objects and possibly a graph traversal.
An example of an algorithm for this would be to walk the graph from 1, and
whenever you find a
Why are you using
Object a

SDG uses the field type and not the current value type to provide conversions
for non primitive types.
As Object is such it is converted to a String. We will look into accomodating
for Object values in the future.
By then please use the
Hello,
I am new to this list and I have a question about Neo4j (I am just using
Neo4j).
I install neo4j server and Jersey Client (REST API) by which I
communicate with the Neo4j database. My problem is how do I look up a
node (get the location of this node : URI) knowing the value of one of
You can use the indexing part of the REST API.
That means after creation you have to add the fields you are interested in to
an index. Then you can retrieve the node(s) later.

I was storing this as an object because this field was acting as parameters
to different functions I was calling and functions had different parameter

Would Generics help here ?

Hi Stephen,
I think the network IO you've measured is consistent with the rest of the
behaviour your've described.
What I'm thinking is that you're simply reaching the limits of create

you're basically testing disk
Hi Jose,
1-i have 2 database (graph), I need to get information from one database
to another without having to take the target database instance of
another database.
One reasonable way of doing this is to use the HA configuration. The HA
protocol will keep two (or many) instances of the
Good catch, forgot to add the in-graph representation of the results to my
mail, thanks for adding that part. Temporary (transient) nodes and
relationships would really rock here, with the advantage that with HA you
have them distributed to all cluster nodes.
Certainly Craig has to add some
Client side sorting makes sense if you know the domain well enough to
know, for example, you will receive a small enough result set to 'fit'
in the client, and want to give the user multiple interactive sort
options without hitting the database again. But I agree that in general
it makes sense

Which JDK (also version) are you using for that, what are the JVM memory

thanks you very much for your answer, but do not know where I can find

Hi Michael,
Just in case we're not talking about the same kind of streaming --
when I think streaming, I think streaming uploads, streaming
downloads, etc.
I'm thinking chunked transfers. That is the server starts sending a response
and then eventually terminates it when the whole response

This can be done?
Hi Georg,
It would at least have to be an iterator over pages - otherwise the results
tend to be fine-grained and so horribly inefficient for sending over a network.

That would need to hold resources on the server (potentially for an
indeterminate amount of time) since it must be stateful. In general, stateful
apis do not scale well in cases of dynamic queries.

Hi Georg,
And you would want to reuse your connection so you don't have to pay this
penalty per request
Just asking how would duch a REST Resource iterator look like -URI, verbs,
request,response formats?
I assume then evety query (index,traversal) would just return the iterator URI
for later
Maven 2 solved the problem.
I submitted a pull request from https://github.com/kevmoo/community to
explain such in the readme.
