    In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

    Go to project selector

    Verify that billing is enabled for your Google Cloud project.

    Enable the BigLake API, if it is not already enabled.

    Roles required to enable APIs

    To enable APIs, you need the serviceusage.services.enable permission. If you created the project, then you likely already have this permission through the Owner role (roles/owner). Otherwise, you can get this permission through the Service Usage Admin role (roles/serviceusage.serviceUsageAdmin). Learn how to grant roles.

gcloud

如需使用 gcloud 描述目录，请运行 gcloud biglake iceberg catalogs describe 命令。

gcloud biglake iceberg catalogs describe CATALOG_ID \
    --project="PROJECT_ID"

替换以下内容：

  • CATALOG_ID：您的目录的 ID。
  • PROJECT_ID：您的 Google Cloud 项目 ID。

REST

如需使用 REST API 检索目录详细信息和配置，请向 GetIcebergCatalog 端点发出 GET 请求：

GET /iceberg/v1/restcatalog/extensions/projects/PROJECT_ID/catalogs/CATALOG_ID

响应包含一个 IcebergCatalog JSON 对象，用于描述目录配置。

替换以下内容：

  • PROJECT_ID：您的 Google Cloud 项目 ID。
  • CATALOG_ID：您的目录的 ID。
