Anexar um banco de dados usando um modelo do Azure Resource Manager

Você pode usar um modelo do Azure Resource Manager para anexar um banco de dados a um cluster existente.

Use as seguintes etapas para anexar um banco de dados:

1. Crie um modelo usando as informações na tabela a seguir para ajudá-lo a configurá-lo.

   Parâmetro	Descrição	Exemplo
   followerClusterName	O nome do cluster de seguidor; em que o modelo será implantado.
   NomeDeConfiguraçõesDeBancoDeDadosAnexadas	O nome do objeto de configurações de banco de dados anexado. O nome pode ser qualquer cadeia de caracteres exclusiva no nível do cluster.
   databaseName	O nome do banco de dados a ser seguido. Para seguir todos os bancos de dados do líder, use '*'.
   leaderClusterResourceId	A ID do recurso do cluster líder.
   defaultPrincipalsModificationKind	O tipo de modificação principal padrão.	Pode ser Union, Replace ou None. Para obter mais informações sobre o tipo de modificação padrão do principal, consulte o comando de controle de tipo de modificação do principal .
   tabelasAIncluir	A lista de tabelas a serem incluídas. Para incluir todas as tabelas começando com 'Logs', use ["Logs*"].	["table1ToInclude", "table2ToInclude"]
   tablesToExclude	A lista de tabelas a serem excluídas. Para excluir todas as tabelas, use ["*"].	["table1ToExclude", "table2ToExclude"]
   tabelasExternasIncluir	A lista de tabelas a serem incluídas. Para incluir todas as tabelas externas começando com 'Logs', use ["Logs*"].	["ExternalTable1ToInclude", "ExternalTable2ToInclude"]
   tabelasExternasParaExcluir	A lista de tabelas a serem excluídas. Para excluir todas as tabelas externas, use ["*"].	["ExternalTable1ToExclude", "ExternalTable2ToExclude"]
   visõesMaterializadasParaIncluir	A lista de visões materializadas a serem incluídas. Para incluir todas as visões materializadas começando com 'Logs', use ["Logs*"].	["Mv1ToInclude", "Mv2ToInclude"]
   visõesMaterializadasParaExcluir	A lista de exibições materializadas a serem excluídas. Para excluir todas as exibições materializadas, use ["*"].	["Mv11ToExclude", "Mv22ToExclude"]
   funçõesParaIncluir	A lista de funções a serem incluídas.	["FunctionToInclude"]
   funçõesParaExcluir	A lista de funções a serem excluídas.	["FunctionToExclude"]
   local	O local de todos os recursos. O líder e o seguidor devem estar no mesmo local.

Desanexar o banco de dados seguidor anexado do cluster de seguidor usando C#**

O cluster de seguidores pode desanexar qualquer banco de dados de seguidor que esteja anexado da seguinte maneira:

var tenantId = "xxxxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxx"; //Directory (tenant) ID
var clientId = "xxxxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxx"; //Application ID
var clientSecret = "PlaceholderClientSecret"; //Client Secret
var followerSubscriptionId = "xxxxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxx";
var credentials = await ApplicationTokenProvider.LoginSilentAsync(tenantId, clientId, clientSecret);
var resourceManagementClient = new KustoManagementClient(credentials) { SubscriptionId = followerSubscriptionId };
var followerResourceGroupName = "testrg";
//The cluster and database attached database configuration are created as part of the prerequisites
var followerClusterName = "follower";
var attachedDatabaseConfigurationsName = "attachedDatabaseConfiguration";
await resourceManagementClient.AttachedDatabaseConfigurations.DeleteAsync(
    followerResourceGroupName, followerClusterName, attachedDatabaseConfigurationsName
);
