Excluir um esquema de dados estruturados

Só é possível excluir um esquema se todos os documentos associados a ele forem excluídos. Caso contrário, a tentativa falha. Depois de excluir um esquema, você pode chamar o método schemas.create para criar um novo.

Para excluir um esquema de dados estruturados, siga estas etapas:

REST

1. Encontre o ID do repositório de dados. Se você já tiver o ID do repositório de dados, pule para a próxima etapa.

   1. No console do Google Cloud, acesse a página Criador de agentes e, no menu de navegação, clique em Repositórios de dados.

      Acesse a página "Repositórios de dados"

   2. Clique no nome do seu repositório de dados.

   3. Na página Dados do seu repositório de dados, encontre o ID do repositório.

2. Exclua o esquema.

   curl -X DELETE \
   -H "Authorization: Bearer $(gcloud auth print-access-token)" \
   -H "Content-Type: application/json" \
   "https://discoveryengine.googleapis.com/v1beta/projects/PROJECT_ID/locations/global/collections/default_collection/dataStores/DATA_STORE_ID/schemas/default_schema"
   

   • PROJECT_ID: o ID do seu projeto.
   • DATA_STORE_ID: o ID do repositório de dados.
