Could you create issue for it ? And we fix it.

Hi, no problem. Now I develop REST-driver for Doctrine2. And I need that,
because Doctrine2 creates query in format uses aliases, example:
SELECT t0.@rid AS rid1, t0.objectId AS objectId2, t0.languageId AS
languageId3, t0.name AS name4, t0.info AS info5, t0.position AS position6,t0

Re: [orientdb] does oriented scale for this
Hi Alan, what are your usage patterns once the database is filled? I mean is it mostly read/traverse on graph?

Here's some numbers to frame what I'd be trying to model in the graph. - I will have approximately 35 billion vertices. - Each vertex will have 4 properties (2 longs, an int, and 1 string). - I will only need 2 edge types (a 1:1 and a 1:many relationship). - I actually don't need a single graph for all 35 billion nodes, I could get away with 3000 separate graphs (approx 11 million nodes per graph). since my application would always be querying 1 of the 3000 areas of the graph. Sorry I can't divulge more on what I'm modeling. As a test, I generated a small graph (1 of my 3000) and ended up with with 2 million vertices and 2 million edges which was 1.1GB on disk. As a ballpark figure I estimated my complete data footprint to be approx. 20TB. Any ideas, general suggestions on architecting such a (large?) distributed graph?

Re: [orientdb] Can someone explain the following Graph Properties please?
Hi, if I remember well. 2013/12/27 Dante j.singh.lo...@gmail.com *alter database custom useClassForEdgeLabel=false* If true, edges labels are modeled as subclasses of E (the top edge class). In this way you can query for example: SELECT * FROM Friend instead of: SELECT * FROM E WHERE label = Friend It's a matter of efficiency. I guess that if useClassForEdgeLabel = true, you can't use lightweight edges. *alter database custom useClassForVertexLabel=false* The same thing as for edges. If your query always require to discriminate vertices / edges by their label, using classes for label it's a good idea. *alter database custom useVertexFieldsForEdgeLabels=false* If this is true edges are lightweight, and their label is attached to the in/out field for the respective vertices. Consider docA -- friendOf -- docB: you will find a field out_friendOf in docA and a field in_friendOf in docB. In this case the isn't any document representing the edge, just those two fields. It would be nice having confirm from Luca or his team. Cheers, Riccardo -- --- You received this message because you are subscribed to the Google Groups OrientDB group.

[orientdb] performance implications of subclasses
If I create subclasses, does this impact the query performance of the master class? For example, if I have Sporting Goods, then subclasses tennis rackets, golf clubs, etc, when i select from sportinggoods, does this impact the overall query performance of querying all the subclasses as well? This would be opposed to keeping all of the different sporting goods in the sporting good class together. -- --- You received this message because you are subscribed to the Google Groups OrientDB group.
