hi,
sorry for the noob question but i am using the graph database but some
vertices i would like them to be documents.
for example the user vertex has a lot of sub documents for the location,
phones etc.
can I do in my code ODocument od=vertex? and then how to save it? can I use
the variables
well... I guess, I could use some generic class for all entities, so there
is only one class - *Item*, with type and userId attributes on each
node, ex:
- *User*(id:123,name:john,age:99)-*Item*
(type:user, userId:123, name:john,age:99)
-
Noone can help me with this ?

Hi. I am using the setProperty but I want to keep nested documents in that
property like options for the user or accounts that are not just list
string but maps. Any nice way of doing this with a vertex?
if i use a document object can i create edges for it? because my data is
highly connected.
Hi Stefan,
could you give us additional information about this machine? eg operating

Okay that's perfect. Thanks for the clarification. Definitely need the
documents to be updated to help understand the duality of the database and
the differences between the two modes. Many times the tutorials/videos will
describe an approach and its not clear if they are talking about a vertex
Hi Aris,
A vertex is not a document but does make use of one internally. You can
treat a vertex like a document in that you can call setProperty with the
same types that ODocument.field() can use.
Do note that save() is implicit when using a vertex.
If you don't wish to use OrientVertex
Hi Cho,
You could use, let's say, 1,000 shards for your client and provide an hash
function that return one of such shard. In this way you can still
partitionate your data.

You're looking up Occupation.id, so an index there would be needed. The
rule of the thumb is: create indexes to speedup lookups, like you would do
with a RDBMS.

When you say nested documents, do you mean like a map or set of embedded or
linked documents?
You can use all the same types in a vertex as you can with a document.
Just think of an OrientVertex as a hybrid of a node and a document. Just
stick with the Vertex and create edges for it while
Agreed! That's something we're working on to improve the documentation and

Hi Stas,
you could implement a hook for this. You can do this in Java or Javascript
(see http://www.orientechnologies.com/docs/last/Hook.html ), just ensure to

onBeforeUpdate
* let your hook functions return RECORD_CHANGED
Thanks all for the suggestions. From what I've understood so far, I think
it's better to go with Orientdb-Lucene for now. I don't think its worth the
effort to make ES work with OrientDB as it clearly requires some additional
work in updating the indices in ES, since the application I am working
1) Is there any way to get query explanations for gremlin queries like

2) My understanding is that gremlin queries are translated into osql
queries, is there any way to see this translation? It would be helpful for
performance tuning and learning osql.
