Database class

Pacote:
@azure/cosmos

Operações para ler ou excluir um banco de dados existente.

Consulte de bancos de dados para criar novos bancos de dados e ler/consultar todos os bancos de dados; use client.databases.

Nota: todas estas operações fazem chamadas contra um orçamento fixo. Você deve projetar seu sistema de modo que essas chamadas sejam dimensionadas sublinearmente com seu aplicativo. Por exemplo, não ligue para database.read() antes de cada chamada item.read(), para garantir que o banco de dados existe; Faça isso uma vez na inicialização do aplicativo.

Propriedades
