OrientDB Fetch Plan/Strategies with Tinkerpop


OrientDB Fetch Plan/Strategies with Tinkerpop

Hope that helps I've been using Tinkerpop 2.6 with OrientDB to manipulate the graph, and I'm running into some performance problems. , You can use OrientDB SQL. Example:
code :
graph.command(new OCommandSQL("select from V where name = 'Luca' fetchplan *:3"))
     .execute();

Tinkerpop 3.1 on OrientDB?

I wish did fix the issue. Orientdb-gremlin is indeed the only available driver, and while it works pretty well for base cases there's some work left for index usage. If you report your cases in a github issue we can have a look. Best is obviously if you submit a PR :)

Does that help what is the best API for Orient to Java for 3.0 snapshot?and how do I 1. connect 2. execute CRUD 3. execute native queries (SQL/Javascript). , This is an example of db connection and execution of an SQL query:
code :
public static void main(String[] args) {

    String DBname="Test";
    String currentPath="remote:localhost/"+DBname;

    OServerAdmin serverAdmin;
    try {
        serverAdmin = new OServerAdmin(currentPath).connect("root", "root"); 
        if(serverAdmin.existsDatabase()){  

            OrientGraph g=new OrientGraph(currentPath); 

            Iterable<Vertex> result=g.command(new OCommandSQL("select from Person")).execute(); 
            for(Vertex v:result){ 
                String rid=v.getId().toString();
                String name=v.getProperty("name");
                String surname=v.getProperty("surname");
                System.out.println(rid + " " + name + " " + surname);  
            }

            g.shutdown(); 

        }
        serverAdmin.close(); 
    } catch (IOException e) {
        e.printStackTrace(); 
    }   
}

How can we use Tinkerpop Blueprints in Orientdb?

How can we use Tinkerpop Blueprints in Orientdb?

fixed the issue. Will look into that further The latest versions of OrientDB natively implement the Blueprints API, so you are "using Blueprints" by virtue of using OrientDB. Pipes is a general dataflow framework and can be used with any Blueprints graph. Use Maven and add Pipes and OrientDB as dependencies in order to construct your project as maven will help manage all the dependencies for you.
