管理和查找特征

了解如何管理和查找特征。

创建特征

为现有实体类型创建单个特征。如需在单个请求中创建多个特征，请参阅批量创建特征。

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

从区域下拉列表中选择一个区域。
在特征表中，查看实体类型列，然后点击要向其添加特征的实体类型。
点击添加特征以打开添加特征窗格。
为特征指定名称、值类型和（可选）说明。
如需启用特征值监控（预览版），请在特征监控下选择替换实体类型监控配置，然后输入快照之间的天数。此配置会替换特征实体类型上的任何现有或未来监控配置。如需了解详情，请参阅特征值监控。
如需添加更多特征，请点击添加其他特征。
点击保存。

REST

如需为现有实体类型创建特征，请使用 featurestores.entityTypes.features.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。
FEATURE_ID：特征的 ID。
DESCRIPTION：特征的说明。
VALUE_TYPE：特征的值类型。

HTTP 方法和网址：

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

请求 JSON 正文：

{
  "description": "DESCRIPTION",
  "valueType": "VALUE_TYPE"
}

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/ENTITY_TYPE_ID?featureId=FEATURE_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/ENTITY_TYPE_ID?featureId=FEATURE_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/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.aiplatform.v1.CreateFeatureOperationMetadata",
    "genericMetadata": {
      "createTime": "2021-03-02T00:04:13.039166Z",
      "updateTime": "2021-03-02T00:04:13.039166Z"
    }
  }
}

批量创建特征

为现有类型批量创建特征。对于批量创建请求，Vertex AI Feature Store（旧版）一次创建多个特征，与 featurestores.entityTypes.features.create 方法相比，创建大量特征速度更快。

网页界面

请参阅创建特征。

REST

如需为现有实体类型创建一个或多个特征，请使用 featurestores.entityTypes.features.batchCreate 方法发送 POST 请求，如以下示例所示。

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。
PARENT：要在其下创建特征的实体类型的资源名称。要求的格式：
projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID
FEATURE_ID：特征的 ID。
DESCRIPTION：特征的说明。
VALUE_TYPE：特征的值类型。
DURATION：（可选）快照之间的时间间隔（以秒为单位）。该值必须以“s”结尾。

HTTP 方法和网址：

POST https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID/features:batchCreate

请求 JSON 正文：

{
  "requests": [
    {
      "parent" : "PARENT_1",
      "feature": {
        "description": "DESCRIPTION_1",

    },

          }
        }
      },
      "featureId": "FEATURE_ID_2"
    }
  ]
}

如需发送请求，请选择以下方式之一：

curl

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 \

搜索特征

根据一个或多个属性（例如特征 ID、实体类型 ID 或特征说明）搜索特征。Vertex AI Feature Store（旧版）在给定位置搜索所有特征存储区和实体类型。您还可以通过过滤特定 featurestores、值类型和标签来限制结果。

如需列出所有特征，请参阅列出特征。

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

从区域下拉列表中选择一个区域。
点击特征表的过滤条件字段。
选择一个要作为过滤依据的属性（例如特征），以返回其 ID 中的任何位置包含匹配字符串的特征。
输入过滤条件的值，然后按 Enter 键。Vertex AI Feature Store（旧版）会在特征表中返回结果。
如需添加其他过滤条件，请再次点击过滤条件字段。

REST

如需搜索特征，请使用 featurestores.searchFeatures 方法发送 GET 请求。以下示例使用多个搜索参数，这些参数以 featureId:test AND valueType=STRING 形式编写。查询将返回 ID 中包含 test 且其值为 STRING 类型的特征。
