[orientdb] [Announcement] OrientDB and TinkerPop 3

[Luca Garulli]

Hi guys,

I'm glad to announce that the OrientDB Team has started supporting
officially the TinkerPop 3 standard in the "develop" branch, namely
OrientDB v3.0.

Michael Pollmeier (@mpollmeier), the author of the already excellent
OrientDB-Gremlin driver, transferred it under the OrientDB umbrella:

https://github.com/orientechnologies/orientdb-gremlin

Together with Michael, also Marvin Froeder (@velo) joined the team as
committer of the project. They will work, together with the OrientDB team,
to make this driver ready for OrientDB v3.0. From the OrientDB side, the
owner of this project is Enrico Risa (@maggiolo00).

Guys, we're looking for new contributors. The roadmap is still open. So far
the most important things are:

   1. Better support for indexes
   2. Usage of the new GraphAPI in the OrientDB core 3.0
   3. Better coverage of TinkerPop 3 features

By transferring the original project the entire history and issues are
preserved. if you are already using it, please reset the master source of
the git repository to it.


*Is this an amazing news?*


Best Regards,

Luca Garulli
Founder & CEO
OrientDB LTD

[orientdb] Recover all embedded records in any class

[Academia Learning Centro de inglés y de formación]

Hello, I wanted to ask a question regarding the inscribed objects.

Is there a way to retrieve all the objects of a class, for example class 
City and retrieve all the City records, including those inscribed in other 
records?


Thanks.

Hi, thank you for answering me.
An example:

{
"result": [
{
"@type": "d",
"@rid": "#21:0",
"@version": 1,
"@class": "Curso",
"City": {
"@type": "d",
"@version": 0,
"@class": "City",
"name": "Valenzuela"
},
"name": "curso 1"
},
{
"@type": "d",
"@rid": "#25:0",
"@version": 1,
"@class": "City",
"name": "bolaños"
},
{
"@type": "d",
"@rid": "#26:0",
"@version": 1,
"@class": "City",
"name": "almagro"
},
{
"@type": "d",
"@rid": "#25:0",
"@version": 1,
"@class": "Country",
"City": {
"@type": "d",
"@version": 0,
"@class": "City",
"name": "Madrid"
},
"name": "curso 1"
},
]

}

I want to get all the cities, in total 4.
But I do not know what classes are embedded
I need something like:

Select * from City

Select * from V where @class = 'City'


And get the 4 cities (2 records and 2 embedded)

thanks

Hi,
you could use this query

select expand($c)
let $a = ( select expand(City) from v),
$b = ( select from city ),
$c = unionAll($a,$b)

Best regards,
Alessandro
