管理实体类型

了解如何创建、列出和删除实体类型。

创建实体类型

创建实体类型，以便可以创建其相关特征。

网页界面

在 Google Cloud 控制台的“Vertex AI”部分，转到特征页面。

转到“特征”页面

在操作栏中，点击创建实体类型，打开创建实体类型窗口。
从区域下拉列表中选择包含您要在其中创建实体类型的特征存储区的区域。
选择特征存储区。
指定实体类型的名称。
如果您想要包含实体类型的说明，请输入说明。
如需启用特征值监控（预览版），请将监控设置为已启用，然后以天为单位指定快照间隔。此监控配置适用于此实体类型下的所有特征。如需了解详情，请参阅特征值监控。
点击创建。

Terraform

以下示例会创建一个新的特征存储区，然后使用 google_vertex_ai_featurestore_entitytype Terraform 资源在该特征存储区中创建一个名为 featurestore_entitytype 的实体类型。

如需了解如何应用或移除 Terraform 配置，请参阅基本 Terraform 命令。

# Featurestore name must be unique for the project
resource "random_id" "featurestore_name_suffix" {
  byte_length = 8
}

resource "google_vertex_ai_featurestore" "featurestore" {
  name   = "featurestore_${random_id.featurestore_name_suffix.hex}"
  region = "us-central1"
  labels = {
    environment = "testing"
  }

  online_serving_config {
    fixed_node_count = 1
  }

  force_destroy = true
}

output "featurestore_id" {
  value = google_vertex_ai_featurestore.featurestore.id
}

resource "google_vertex_ai_featurestore_entitytype" "entity" {
  name = "featurestore_entitytype"
  labels = {
    environment = "testing"
  }

  featurestore = google_vertex_ai_featurestore.featurestore.id

  monitoring_config {
    snapshot_analysis {
      disabled = false
    }
  }

  depends_on = [google_vertex_ai_featurestore.featurestore]
}

REST

如需创建实体类型，请使用 featurestores.entityTypes.create 方法发送 POST 请求。

在使用任何请求数据之前，请先进行以下替换：

LOCATION_ID：特征存储区所在的区域，例如 us-central1。
PROJECT_ID：您的项目 ID。
FEATURESTORE_ID：特征存储区的 ID。
ENTITY_TYPE_ID：实体类型的 ID。
DESCRIPTION：实体类型的说明。

HTTP 方法和网址：

POST https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes?entityTypeId=ENTITY_TYPE_ID

请求 JSON 正文：

{
  "description": "DESCRIPTION"
}

如需发送请求，请选择以下方式之一：

curl

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI，或者使用了 Cloud Shell，这会使您自动登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

curl -X POST \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    -d @request.json \
    "https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes?entityTypeId=ENTITY_TYPE_ID"

PowerShell

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes?entityTypeId=ENTITY_TYPE_ID" | Select-Object -Expand Content

您应该会看到类似如下所示的输出。您可以使用响应中的 OPERATION_ID 来获取操作的状态。

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/bikes/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.aiplatform.v1.CreateEntityTypeOperationMetadata",
    "genericMetadata": {
      "createTime": "2021-03-02T00:04:13.039166Z",
      "updateTime": "2021-03-02T00:04:13.039166Z"
    }
  }
}
