      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 information needed when sending non-insert type of requests to the database.

      package main
      
      import (
        "log"
      
        "github.com/ultipa/ultipa-go-sdk/sdk"
        "github.com/ultipa/ultipa-go-sdk/sdk/configuration"
      )
      
      func main() {
      
        config, _ := configuration.NewUltipaConfig(&configuration.UltipaConfig{
          Hosts:    []string{"192.168.1.85:60061", "192.168.1.86:60061", "192.168.1.87:60061"},
          Username: "***",
          Password: "***",
        })
      
        conn, _ := sdk.NewUltipa(config)
      
        requestConfig := &configuration.RequestConfig{
          GraphName:   "miniCircle",
          RequestType: configuration.RequestType_Task,
        }
      
        uqlResult, err := conn.Uql("find().nodes({@account.year > 2000}) as nodes return nodes{*} limit 5", requestConfig)
      
        log.Print(uqlResult, err)
      
      }
      

      RequestConfig has the following fields:

      Item Type Default Value Description
      GraphName string Name of the graph to use. If not set, use the graphSetName configured when establishing the connection.
      Timeout int32 1000 Request timeout threshold in seconds.
      ClusterId string Specifies the cluster to use.
      Host string Sends the request to a designated host node, or to a random host node if not set.
      UseMaster bool FALSE Sends the request to the leader node to guarantee consistency read if set to true.
      UseControl bool FALSE Sends the request to the control node if set to true.
      RequestType RequestType or int32 0 Sends the requset to a node according to the request type:
      RequestType_Write or 1: to leader node
      RequestType_Task or 2: to algo
      RequestType_Normal or 3: to a random host
      Uql string UQL for internal program
      Timezone string The time zone to use.
      TimezoneOffset int64 The amount of time that the time zone in use differs from UTC in seconds.
      ThreadNum uint32 Number of threads.
      MaxPkgSize int 10M Max package size in bytes, for both sending and receiving.

      InsertRequestConfig

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

      package main
      
      import (
        ultipa "github.com/ultipa/ultipa-go-sdk/rpc"
        "github.com/ultipa/ultipa-go-sdk/sdk"
        "github.com/ultipa/ultipa-go-sdk/sdk/configuration"
        "github.com/ultipa/ultipa-go-sdk/sdk/structs"
      )
      
      func main() {
      
        config, _ := configuration.NewUltipaConfig(&configuration.UltipaConfig{
          Hosts:    []string{"192.168.1.85:60061", "192.168.1.86:60061", "192.168.1.87:60061"},
          Username: "***",
          Password: "***",
        })
      
        conn, _ := sdk.NewUltipa(config)
      
        requestConfig := &configuration.RequestConfig{
          GraphName: "test",
        }
        insertRequestConfig := &configuration.InsertRequestConfig{
          RequestConfig: requestConfig,
          InsertType:    ultipa.InsertType_OVERWRITE,
        }
      
        var nodes []*structs.Node
      
        newNode1 := structs.NewNode()
        newNode1.Schema = "card"
        newNode1.ID = "ULTIPA8000000000000001"
        newNode1.Set("amount", float32(3235.2))
        nodes = append(nodes, newNode1)
      
        newNode2 := structs.NewNode()
        newNode2.Schema = "client"
        newNode2.ID = "ULTIPA8000000000000007"
        newNode2.Set("level", int32(77))
        nodes = append(nodes, newNode2)
      
        conn.InsertNodesBatchAuto(nodes, insertRequestConfig)
      
      }
      

      InsertRequestConfig has the following fields:

      Item Type Default Value Description
      GraphName string Name of the graph to use. If not set, use the graphSetName configured when establishing the connection.
      Timeout int32 1000 Request timeout threshold in seconds.
      ClusterId string Specifies the cluster to use.
      Host string Sends the request to a designated host node, or to a random host node if not set.
      UseMaster bool FALSE Sends the request to the leader node to guarantee consistency read if set to true.
      UseControl bool FALSE Sends the request to the control node if set to true.
      RequestType RequestType or int32 0 Sends the requset to a node according to the request type:
      RequestType_Write or 1: to leader node
      RequestType_Task or 2: to algo
      RequestType_Normal or 3: to a random host
      Uql string UQL for internal program
      Timezone string The time zone to use.
      TimezoneOffset int64 The amount of time that the time zone in use differs from UTC in seconds.
      ThreadNum uint32 Number of threads.
      MaxPkgSize int 10M Max package size in bytes, for both sending and receiving.
      InsertType ultipa.InsertType or int32 0 Insert mode: InsertType_NORMAL (or 0), InsertType_OVERWRITE (or 1), InsertType_UPSERT (or 2).
      CreateNodeIfNotExist bool FALSE Whether to create start/end nodes of an edge if the end nodes do not exist in the graph.
      Silent bool FALSE Whether to keep slient after success insertion, i.e., whether to return the inserted nodes or edges.
