Hi Marc,

1. Creation of property keys and indices in the schema + commit

      graph = (Janusgraph) GraphDBConfigurator.getGraph()

      mgmt = graph.openManagement()

      

     For Vertex ->

           propertyKey = mgmt.makePropertyKey(propertyKeyName).dataType (String.class).cardinality(Cardinality.SET).make()

          if(existingIndex) 

                janusgraphIndex = mgmt.getGraphIndex(VERTEX_INDEX_NAME)

                mgmt.addIndex(janusgraphIndex, propertyKey)

          else

               indexBuilder = mgmt.buildIndex(VERTEX_INDEX_NAME,  Vertex.class)

               if(cardinality is SET)

                        indexBuilder.addKey(propertyKey, String.class.equals(propertyKey.dataType) ? Mapping.TEXT.asParameter() : Mapping.DEFAULT.asParameter())

               else

                        indexBuilder.addKey(propertyKey, String.class.equals(propertyKey.dataType) ? Mapping.TEXTSTRING.asParameter() : Mapping.DEFAULT.asParameter())

  

    For Edge ->

            propertyKey = mgmt.makePropertyKey(propertyKeyName).dataType (String.class).cardinality(Cardinality.SINGLE).make()

             propertyKey = mgmt.makePropertyKey(propertyKeyName).dataType (String.class).cardinality(Cardinality.SINGLE).make()

          if(existingIndex) 

                janusgraphIndex = mgmt.getGraphIndex(EDGE_INDEX_NAME)

                mgmt.addIndex(janusgraphIndex, propertyKey)

          else

               indexBuilder = mgmt.buildIndex(EDGE_INDEX_NAME,  Vertex.class)

               if(cardinality is SET)

                        indexBuilder.addKey(propertyKey, String.class.equals(propertyKey.dataType) ? Mapping.TEXT.asParameter() : Mapping.DEFAULT.asParameter())

               else

                        indexBuilder.addKey(propertyKey, String.class.equals(propertyKey.dataType) ? Mapping.TEXTSTRING.asParameter() : Mapping.DEFAULT.asParameter())

         

            mgmt.commit();

    

       3.   Query of a vertex based on a property value in another transaction

             Let say i created a property key "domain_vertex_key1_s" for vertex

             Query = g.V().has("domain_vertex_key1_s", "val1);

             

             Let say I created a property key "domain_edge_key1_s" for edge

            

             Query = g.V().has("domain_vertex_key1_s","val2");

Hi Harshit,

Can you please describe the steps you have taken in more detail:

• creation of property keys and indices in the schema + commit,
• creation of a vertex with a property in one committed transaction,
• query of a vertex based on a property value in another transaction.
