      Query Acceleration

      This section introduces methods on a Connection object for managing the LTE status for properties, and their indexes and full-text indexes. These mechanisms can be employed to accelerate queries.

      Each example focuses solely on the method's usage. For a complete code example, please refer to the full example.

      LTE

      lte()

      Loads one custom property of nodes or edges to the computing engine for query acceleration.

      Parameters:

      • DBType: Type of the property (node or edge).
      • str: Name of the property.
      • str (Optional): Name of the schema; all schemas are specified when it is ignored.
      • RequestConfig (Optional): Configuration settings for the request.

      Returns:

      • UltipaResponse: Result of the request.

      # Loads the edge property @relatesTo.type to engine in graphset 'UltipaTeam' and prints error code
      
      requestConfig = RequestConfig(graphName="UltipaTeam")
      
      response = Conn.lte(DBType.DBEDGE, 'type', 'relatesTo', requestConfig)
      print(response.status.code)

      ufe()

      Unloads one custom property of nodes or edges from the computing engine to save the memory.

      Parameters:

      • DBType: Type of the property (node or edge).
      • str: Name of the property.
      • str (Optional): Name of the schema; all schemas are specified when it is ignored.
      • RequestConfig (Optional): Configuration settings for the request.

      Returns:

      • Response: Result of the request.

      # Unloads the edge property @relatesTo.type from engine in graphset 'UltipaTeam' and prints error code
