Atualizando um domínio () SDK

Este exemplo usa o cliente Python de OpenSearchServicebaixo nível AWS SDK for Python (Boto) do para verificar se um domínio está qualificado para atualização para uma versão específica, atualizá-lo e verificar continuamente o status do upgrade.

# You can use the CLI and run 'aws configure' to set access key, secret
# key, and default Region.
