      Fields 
      Modifier and Type Field Description
      static String ADD_TABLE_MONITOR
      Adds a table monitor to every table used in the creation of the graph; this table monitor will trigger the graph to update dynamically upon inserts to the source table(s).
      static String ADD_TURNS
      Adds dummy 'pillowed' edges around intersection nodes where there are more than three edges so that additional weight penalties can be imposed by the solve endpoints.
      static String ALLOW_MULTIPLE_EDGES
      Multigraph choice; allowing multiple edges with the same node pairs if set to true, otherwise, new edges with existing same node pairs will not be inserted.
      static String EMBEDDING_TABLE
      If table exists (should be generated by the match/graph match_embedding solver), the vector embeddings for the newly inserted nodes will be appended into this table.
      static String FALSE  
      static String GRAPH_TABLE
      If specified, the created graph is also created as a table with the given name, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria.
      static String IS_PARTITIONED
      Supported values: TRUE FALSE The default value is FALSE.
      static String LABEL_DELIMITER
      If provided the label string will be split according to this delimiter and each sub-string will be applied as a separate label onto the specified edge.
      static String MERGE_TOLERANCE
      If node geospatial positions are input (e.g., WKTPOINT, X, Y), determines the minimum separation allowed between unique nodes.
      static String RECREATE
      If set to TRUE and the graph (using graphName) already exists, the graph is deleted and recreated.
      static String SAVE_PERSIST
      If set to TRUE, the graph will be saved in the persist directory (see the config reference for more information).
      static String SERVER_ID
      Indicates which graph server(s) to send the request to.
      static String TRUE  
      static String USE_RTREE
      Use an range tree structure to accelerate and improve the accuracy of snapping, especially to edges.

      • MERGE_TOLERANCE

        public static final String MERGE_TOLERANCE
        If node geospatial positions are input (e.g., WKTPOINT, X, Y), determines the minimum separation allowed between unique nodes. If nodes are within the tolerance of each other, they will be merged as a single node. The default value is '1.0E-5'.

        Constant Field Values

      • SAVE_PERSIST

        public static final String SAVE_PERSIST
        If set to TRUE, the graph will be saved in the persist directory (see the config reference for more information). If set to FALSE, the graph will be removed when the graph server is shutdown. Supported values: The default value is FALSE.
        See Also:
        Constant Field Values

      • ADD_TABLE_MONITOR

        public static final String ADD_TABLE_MONITOR
        Adds a table monitor to every table used in the creation of the graph; this table monitor will trigger the graph to update dynamically upon inserts to the source table(s). Note that upon database restart, if SAVE_PERSIST is also set to TRUE, the graph will be fully reconstructed and the table monitors will be reattached. For more details on table monitors, see GPUdb.createTableMonitor. Supported values: The default value is FALSE.
        See Also:
        Constant Field Values

      • GRAPH_TABLE

        public static final String GRAPH_TABLE
        If specified, the created graph is also created as a table with the given name, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. The table will have the following identifier columns: 'EDGE_ID', 'EDGE_NODE1_ID', 'EDGE_NODE2_ID'. If left blank, no table is created. The default value is ''.
        See Also:
        Constant Field Values

      • ADD_TURNS

        public static final String ADD_TURNS
        Adds dummy 'pillowed' edges around intersection nodes where there are more than three edges so that additional weight penalties can be imposed by the solve endpoints. (increases the total number of edges). Supported values: The default value is FALSE.
        See Also:
        Constant Field Values

      • SERVER_ID

        public static final String SERVER_ID
        Indicates which graph server(s) to send the request to. Default is to send to the server with the most available memory.
        See Also:
        Constant Field Values

      • USE_RTREE

        public static final String USE_RTREE
        Use an range tree structure to accelerate and improve the accuracy of snapping, especially to edges. Supported values: The default value is TRUE.
        See Also:
        Constant Field Values

      • LABEL_DELIMITER

        public static final String LABEL_DELIMITER
        If provided the label string will be split according to this delimiter and each sub-string will be applied as a separate label onto the specified edge. The default value is ''.
        See Also:
        Constant Field Values

      • ALLOW_MULTIPLE_EDGES

        public static final String ALLOW_MULTIPLE_EDGES
        Multigraph choice; allowing multiple edges with the same node pairs if set to true, otherwise, new edges with existing same node pairs will not be inserted. Supported values: The default value is TRUE.

        public static final String EMBEDDING_TABLE
        If table exists (should be generated by the match/graph match_embedding solver), the vector embeddings for the newly inserted nodes will be appended into this table. The default value is ''.
