      Request Configuration

      All querying methods support an optional request configuration parameter (RequestConfig or InsertRequestConfig) to customize the behavior of requests made to the database. This parameter allows you to specify various settings, such as graphset name, timeout, and host, to tailor your requests according to your needs.

      RequestConfig

      RequestConfig defines the settings needed when sending non-insert requests to the database.

      public class Main {
          public static void main(String[] args) {
              UltipaConfiguration myConfig = UltipaConfiguration.config()
                  // URI example: .hosts("mqj4zouys.us-east-1.cloud.ultipa.com:60010")
                  .hosts("192.168.1.85:60061,192.168.1.86:60061,192.168.1.87:60061")
                  .username("<username>")
                  .password("<password>");
      
              UltipaClientDriver driver = null;
              try {
                  driver = new UltipaClientDriver(myConfig);
                  Connection client = driver.getConnection();
      
                  // Specifies 'amz' as the target graphset and sets to use the leader node of the cluster 
                  RequestConfig requestConfig = new RequestConfig();
                  requestConfig.setGraphName("amz");
                  requestConfig.setUseMaster(true);
              
                  Response response = client.uql("find().nodes() as nodes return nodes{*} limit 10", requestConfig);
                  List<Node> nodeList = response.alias("nodes").asNodes();
                  for(int i = 0; i < nodeList.size(); i ++){
                      System.out.println("node " + i + " is: " + nodeList.get(i).toJson());
                  }
              } finally {
                  if (driver != null) {
                      driver.close();
                  }
              }
          }
      }
      

      RequestConfig has the following fields:

      Field
      Type
      Default
      Description
      graphName String Name of the graph to use, or the defaultGraph configured when establishing the connection if not set.
      timeout Integer 15 Timeout in seconds for the request, or the timeout configured when establishing the connection if not set.
      host String Sends the request to a designated host node, or to a random host node if not set.
      useMaster Boolean false Sends the request to the leader node to guarantee consistency read if set to true.
      threadNum Integer Number of threads.

      InsertRequestConfig

      InsertRequestConfig defines the settings needed when sending data insertion or deletion requests to the database.

      public class Main {
          public static void main(String[] args) {
              UltipaConfiguration myConfig = UltipaConfiguration.config()
                  // URI example: .hosts("mqj4zouys.us-east-1.cloud.ultipa.com:60010")
                  .hosts("192.168.1.85:60061,192.168.1.86:60061,192.168.1.87:60061")
                  .username("<username>")
                  .password("<password>");
      
              UltipaClientDriver driver = null;
              Connection client;
              try {
                  driver = new UltipaClientDriver(myConfig);
                  client = driver.getConnection();
      
                  // Specifies 'test' as the target graphset and sets the insert mode to OVERWRITE
                  InsertRequestConfig insertRequestConfig = new InsertRequestConfig();
                  insertRequestConfig.setGraphName("test");
                  insertRequestConfig.setInsertType(Ultipa.InsertType.OVERWRITE);
              
                  List<Node> nodeList = new ArrayList<>();
                  Node node1 = new Node();
                  node1.setSchema("client");
                  node1.setID("CLIENT00001");
                  nodeList.add(node1);
                  Node node2 = new Node();
                  node2.setSchema("card");
                  node2.setID("CARD00004");
                  nodeList.add(node2);
                
                  client.insertNodesBatchAuto(nodeList, insertRequestConfig);
              } finally {
                  if (driver != null) {
                      driver.close();
                  }
              }
          }
      }
      

      InsertRequestConfig has the following fields:

      Field
      Type
      Default
      Description
      graphName String Name of the graph to use, or the defaultGraph configured when establishing the connection if not set.
      timeout Integer 15 Timeout in seconds for the request, or the timeout configured when establishing the connection if not set.
      host String Sends the request to a designated host node, or to a random host node if not set.
      useMaster Boolean false Sends the request to the leader node to guarantee consistency read if set to true.
      insertType Ultipa.InsertType NORMAL Insert mode (NORMAL, UPSERT, OVERWRITE)
      silent Boolean true Whether to keep silent after success insertion, i.e., whether to return the inserted nodes or edges.
      createNodeIfNotExist Boolean false Whether to create start/end nodes of an edge if the end nodes do not exist in the graph.
