Does it make sense to create a graph with a very large amount edges between
vertices? For example if I have sellers and products as vertices and each
net user by buying something adding new edge (a edge from a seller to a
product with data and amount properties means that a seller sold a

Hi,
We have costumer in production which has 700 000 edges for one vertex and
does not experience performance problems so that is what graph databases
are intended for.

Hi,
This problem is fixed in 1.7-RC1 will be available during couple of hours,
could you use it ?
Also please be sure that you do not have embedded jna version, usually it
is called libjna-java.
We also will provide migration tool (if you need it) for graph database.

Hi,
If you use JSON version of import/export you create the same data
structures as before, so you will have no profit of this.
You should use new LINKBAG data structure to fix this issue.
So you should either use GraphML which operates on the graph model level or
use migration tool which will

Could you tell me what about aggregation? Does OrientDB provide any

in the set of pointed vertex.

Hello,
I have been looking into Graph Databases (and some other NoSQL databases)
recently, and i found a lot of interesting developments going on, including
ArangoDB with its Foxx applications (and Javascript API very similar to
MongoDB) and Neo4J, seemingly the most popular GraphDB currently.
Any updates on this?

This problem occurred against a specific vertex. I have a vertex called
store that connects to products via edges. I deleted the connected products
to that vertex by using delete vertex where @class=products and

This seemed to put that store vertex into an
I think I encountered a similar situation in 1.6.1 where a deleted vertex was

To achieve good performance, durability and thread safety we use pretty
sophisticated algorithm which allows do not fetch lets say all 700 000

So to make it simple you can use only embedded version of
linkbag surrounded by % and : so you should truncate them.

Thanks. I noticed that OEmbeddedRidBag is pretty simple.
One question. When I send OEmbeddedRidBag via binary protocol does it mean
that internally on server side it is stored in Embedded or tree form?
And when can I expect to get embedded not a tree form in document via
binary protocol?
Hi Pawel,
I do not think that providing such level of compatibility is good idea, too
much sources should be spent on this.
Probably in such case users can work in embedded mode.
You see embedded collections they of course will not allow to work with
thousands of links but support of sbtree is
