Database class

Pacote:
@azure/cosmos

Operações para ler ou excluir um banco de dados existente.

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

Observação: todas essas operações fazem chamadas em relação a um orçamento fixo. Você deve projetar seu sistema de modo que essas chamadas sejam dimensionadas sublinearmente com seu aplicativo. Por exemplo, não chame database.read() antes de cada chamada item.read(), para garantir que o banco de dados exista; faça isso uma vez na inicialização do aplicativo.

Propriedades

client
containers

Usado para criar novos contêineres ou consultar/ler todos os contêineres.

Use .database(id) para ler, substituir ou excluir uma de Banco de Dados específica por ID.
