UpdateVikingdbIndex 接口用于修改已存在索引的描述、标量索引、CPU 配额或分片策略。

Go SDK 通过 vikingdb.New(sess) 创建的客户端实例调用 UpdateVikingdbIndex(input) 方法发起索引创建请求，input 参数类型为 vikingdb.UpdateVikingdbIndexInput ，包含索引创建所需的完整配置信息

请求示例 #

package main

import (
    "fmt"
    "os"

    "github.com/volcengine/volcengine-go-sdk/service/vikingdb"
    "github.com/volcengine/volcengine-go-sdk/volcengine"
    "github.com/volcengine/volcengine-go-sdk/volcengine/credentials"
    "github.com/volcengine/volcengine-go-sdk/volcengine/session"
)

func main() {
    var (
       accessKey = os.Getenv("VIKINGDB_AK")
       secretKey = os.Getenv("VIKINGDB_SK")
       region    = "cn-beijing"
    )

    config := volcengine.NewConfig().
       WithRegion(region).
       WithCredentials(credentials.NewStaticCredentials(accessKey, secretKey, ""))

    sess, err := session.NewSession(config)
    if err != nil {
       panic(err)
    }
    svc := vikingdb.New(sess)

    input := &vikingdb.UpdateVikingdbIndexInput{
       CollectionName: volcengine.String("Your Collection Name"),
       IndexName:      volcengine.String("Your Index Name"),
       ProjectName:    volcengine.String("default"),
       Description:    volcengine.String("Your Index Description"),
       ShardCount:     volcengine.Int32(2),
    }

    output, err := svc.UpdateVikingdbIndex(input)
    if err != nil {
       panic(err)
    }
    fmt.Printf("Update index response: %+v\n", output)
