Hi Luca,
The node is traversed from #11:0. The vertices A are connected by an edge
called connects. I need to return all nodes and all links.

Hi,
Registration of function via *registerFunction* is different from its
registration in OFunction. *registerFunction*() is rather for native java
functions, while *OFunction* is for functions on dynamic languages (sql,
JS).
You might call *registerFunction* on client, so the server know

i have two different indices on my vertextype for two different properties.

Is there a possibility to get all elements of the index i specify?
With this method i get all indexedKeys but i just want to get the
indexedKeys of one index
hi,
i have one property X to different type of clusters in an array for example

X - [#11:0,#12:0,#19:0,#11:1,#11:3]
how can i do it pls help me...

It seems you are getting same exception of me, infact getProviderUtil
in OJPAPersistenceProvider it'is not implemented and raise an
UnsupportedOperationException(getProviderUtil) whenever is called.

Hi Wouter,
It is not really that easy to improve performance of subquery with index.
Because in a sub-query you select records from subset created somehow but
not from class.
General approach in this case is to rewrite your query in more efficient
way, change schema or create a manual index.
Hi Bokyum,
The TRAVERSE command is not designed to find all paths between nodes. To
prevent going into a loop it does not traverse nodes that has already been
handled.
To find all paths between vertexes you can use gremlin query or write your
own function.
Best regards,

Hi Artem,
Thanks, I thought as much.
One approach for us would be to denormalize data, but I am looking if there
exists a way where I wouldn't need to maintain multiple classes/indexes for
this to work.
Would it be possible to create an index over multiple classes including the
relations or
And when i never ever want to use SQL? ;)
Ofcourse it would be an easy solution but i dont want to break my design
rules.
I could do this:
1. Select all vertices of the vertex type
2. Iterate over the vertices
3. Get all properties of each vertex and store it in a list
4. return

Hi Wouter,
Would it be possible to create an index over multiple classes including the
relations or something like that?
No, automatic indexing over multiple classes is not supported.
You can try to play with a composite index over in_ARTICLE_SUPP_NR and
other field and do select from article
Hi,
You can always use Orient API if you don't like SQL.
Just get the index from OIndexManager and
call com.orientechnologies.orient.core.index.OIndex#keyCursor, then use
this cursor to iterate over keys.
This is the most efficient way.

Anyone interested to co-op or throw some ideas about it?
Greatly appreciate!

Thanks for the info. Do I understand correctly that a lightweight edge is
an edge without any properties?

Hi,
I am using OrientDB v1.7. Today, I perform a query via API
with OSQLSynchQuery, it returns a wrong result.

ifnull(CreationDate,'',CreationDate) AS __x2,
ifnull(LastActivityDate,'',LastActivityDate) AS __x3,

Hi,
I am using memory graph: my OrientDB graph is an in-memory datagraph over
an Oracle Database.
In OrientDB 1.5 the composite index was working well for memory graph (I

naive BTree impementation as an index
Hi Wouter,
Lightweight edge is the edge that does not created as a record in an
underlying database.
By default OrientDB optimize all edges without properties to lightweight.

Im sorry but i have no idea what you are talking about. How do i get the
OIndexManager? Its an Interface as i can see in
documentation. No method of OrientBaseGraph returns OIndexManager.
When i call graph.getIndices() the iterator contains no index.

I don't use play, but i saw your threads. I also don't use jpa. I'm using
dropwizard that uses hibernate for validation. The hibernate in dropwizard
is somehow causing the jpa to activate. I have no fix for this.

I see you've the default cfg, but the storage.diskCache.bufferSize can't

Cool!
OrientDB allow to do that in more efficient way than pooling. Take a look
at hooks API.

Hello!
I need a hint for a scenario with a tree structure and data inheritance.
There is a simple node hierarchy with a parent-children relationship:
Parent node:
{
'name' : 'parentNode',
'color' : {
inheritable : true,
'value' : 'red'
},
'speed' : {
inheritable : false,

I've been trying to use OrientDB as a RDF store. Sail provides some good

to help you load RDF

I think I've managed to keep the speed consistent by disabling WAL:
