◆ createGraph() [2/2]

CreateGraphResponse kinetica.Kinetica.createGraph (stringgraph_name,
booldirected_graph,
IList< string >nodes,
IList< string >edges,
IList< string >weights,
IList< string >restrictions,
IDictionary< string, string >options = null )
 inline

Creates a new graph network using given nodes, edges, weights, and restrictions.

IMPORTANT: It’s highly recommended that you review the Graphs and Solvers concepts documentation, the Graph REST Tutorial, and/or some graph examples before using this endpoint.

Parameters
graph_nameName of the graph resource to generate.
directed_graphIf set to TRUE, the graph will be directed. If set to FALSE, the graph will not be directed. Consult Directed Graphs for more details. Supported values:
  • true
  • false
The default value is true.
nodesNodes represent fundamental topological units of a graph. Nodes must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS NODE_ID’, expressions, e.g., ‘ST_MAKEPOINT(column1, column2) AS NODE_WKTPOINT’, or constant values, e.g., ‘9, 10, 11 AS NODE_ID’. If using constant values in an identifier combination, the number of values specified must match across the combination.
edgesEdges represent the required fundamental topological unit of a graph that typically connect nodes. Edges must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS EDGE_ID’, expressions, e.g., ‘SUBSTR(column, 1, 6) AS EDGE_NODE1_NAME’, or constant values, e.g., “‘family’, ‘coworker’ AS EDGE_LABEL”. If using constant values in an identifier combination, the number of values specified must match across the combination.
weightsWeights represent a method of informing the graph solver of the cost of including a given edge in a solution. Weights must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS WEIGHTS_EDGE_ID’, expressions, e.g., ‘ST_LENGTH(wkt) AS WEIGHTS_VALUESPECIFIED’, or constant values, e.g., ‘4, 15 AS WEIGHTS_VALUESPECIFIED’. If using constant values in an identifier combination, the number of values specified must match across the combination.
restrictionsRestrictions represent a method of informing the graph solver which edges and/or nodes should be ignored for the solution. Restrictions must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS RESTRICTIONS_EDGE_ID’, expressions, e.g., ‘column/2 AS RESTRICTIONS_VALUECOMPARED’, or constant values, e.g., ‘0, 0, 0, 1 AS RESTRICTIONS_ONOFFCOMPARED’. If using constant values in an identifier combination, the number of values specified must match across the combination.
optionsOptional parameters.
  • 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’.
  • RECREATE: If set to TRUE and the graph (using graph_name ) already exists, the graph is deleted and recreated. Supported values:The default value is FALSE.
  • 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.
  • 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 createTableMonitor. Supported values:The default value is FALSE.
  • 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 ”.
  • 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.
  • IS_PARTITIONED: Supported values:The default value is FALSE.
  • SERVER_ID: Indicates which graph server(s) to send the request to. Default is to send to the server with the most available memory.
  • 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.
  • 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 ”.
  • 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.
  • 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 ”.
The default value is an empty Dictionary.
Returns
Response object containing the result of the operation.
