Pesquisar uma operação de longa duração
Mantenha tudo organizado com as coleções
Salve e categorize o conteúdo com base nas suas preferências.
Para pesquisar uma operação, chame repetidamente o método get_long_running_operation() até que a operação seja concluída. Use um recuo entre cada solicitação de pesquisa. Por exemplo, pesquise a cada 10 segundos.
