Menghapus katalog

Saat Anda menghapus katalog (seperti katalog REST Apache Iceberg atau katalog Apache Hive), sistem akan membatalkan pendaftaran endpoint pengelolaan metadata dari katalog runtime Lakehouse.

Meskipun tindakan ini menghapus katalog dari Lakehouse tanpa batas, tindakan ini tidak otomatis menghapus bucket Cloud Storage yang mendasarinya atau file data tersimpan Anda. Anda tidak dapat menghapus katalog yang masih berisi namespace atau tabel.

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.

Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

Go to project selector

Verify that billing is enabled for your Google Cloud project.

Enable the BigLake API.

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.
