Hi, is there something in OrientDB, similar to the newly introduced entity
graphs in JPA 2.1:

Thanks for the correct syntax.
I am still confused about 2 things:
1) what exactly *expand()* does.
In short, is there a precise definition of *expand()*?
2) I also do not understand why
*select out().name from* *N1*
does not also give me the value of the *name* fields on the vertices
r
Also if anybody knows if graphs are supported.

What about executing the following query:
SELECT sum(out().size()) FROM V
Can it be considered more efficient than iterating over the whole vertices
set or is it the same?

Hi,
OrientDB uses lazy loading technique, so as soon as you browse elements
OrientDB loads it. Obviously not all the loaded stuff remain in memory, but
is flushed away when other elements are loaded (like LRU).

I just realized what you was saying. Sorry. Your suggestion worked.
One more quetion. I have 1M nodes and 3M edges. I wonder if when I
iterate through all the nodes the whole graph is loaded in the memory,
because it needs about 2G of ram to count all the edges.

HI,
But as I have written you use wrong method, you use
*OrientBaseGraph*.countEdges
but should use *OrientVertex*.countEdges
You count edges for current vertex and sum them up, right ?

Hi,
if you've lightweight edges, that is default setting, you cannot count
edges. This is a limitation of lightweight edges. If you need to count
edges (I can't see a real reason for this) you should disable it.
alter database custom useLightweightEdges=false
Look at:

Lets say, I get set of document RIDs from server and assign that to a JS
array docs[] and later want to fetch the specific document referring its
RID using below REST call through AngularJS

Remember, *doc[i]['@rid']* will have # in i
Hi,
Now our event store is almost complete and working quite well on top of

I'm wondering what the best setup/configuration is for our case.

queue
- About 500 - 2000 event messages are
I have upgraded to rc2 but nothig actually changed.
I initialize my graph instance this way
OrientGraph orientGraph = orientGraph = new OrientGraph("plocal:"+dbPAth);
and when i try to count the edges i simply do this
orientGraph.countEdges()
The only function I still have is this OrientBaseGra
No i use 1.7-SNAPSHOT. Where can i find the dependencies for rc2?

Hi,
out() references to set of vertexes that reached by out edges from current
vertex. So when you include it to projection it add a *set* of vertexes
connected to current one.

You can try to check edges presence directly, but it will never work in
multithreading environment.
You should relay on index for this cases.

Do you see the warnings with enabled 1st level cache?
