Uso de bases de datos de seguidor

Adjuntar una base de datos mediante C#

Paquetes NuGet necesarios

• Instale Microsoft.Azure.Management.Kusto.

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 = "followerResourceGroup";
var followerClusterName = "follower";
var attachedDatabaseConfigurationName = "attachedDatabaseConfiguration"
var leaderSubscriptionId = "xxxxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxx";
var leaderResourceGroup = "leaderResourceGroup";
var leaderClusterName = "leader";
var attachedDatabaseConfigurationData = new AttachedDatabaseConfiguration
{
    ClusterResourceId = $"/subscriptions/{leaderSubscriptionId}/resourceGroups/{leaderResourceGroup}/providers/Microsoft.Kusto/Clusters/{leaderClusterName}",
    DatabaseName = "<databaseName>", // Can be specific database name or * for all databases
    DefaultPrincipalsModificationKind = "Union",
    Location = "North Central US"
};
// Table level sharing properties are not supported when using '*' all databases notation.
if (attachedDatabaseConfigurationData.DatabaseName != "*")
{
    // Set up the table level sharing properties - the following is just an example.
    attachedDatabaseConfigurationData.TableLevelSharingProperties = new TableLevelSharingProperties(
        tablesToInclude:new List<string> { "table1" },
        tablesToExclude:new List<string> { "table2" },
        externalTablesToInclude:new List<string> { "exTable1" },
        externalTablesToExclude:new List<string> { "exTable2" },
        materializedViewsToInclude:new List<string> { "matTable1" },

    );
}
await resourceManagementClient.AttachedDatabaseConfigurations.CreateOrUpdateAsync(
    followerResourceGroupName, followerClusterName, attachedDatabaseConfigurationName, attachedDatabaseConfigurationData
);

Adjuntar una base de datos utilizando una plantilla de Azure Resource Manager

Puede usar una plantilla de Azure Resource Manager para adjuntar una base de datos a un clúster existente.

Siga estos pasos para adjuntar una base de datos:

1. Cree una plantilla con la información de la tabla siguiente para ayudarle a configurarla.

   Parámetro	Descripción	Ejemplo
   followerClusterName	Nombre del clúster del seguidor; donde se implementará la plantilla.
   nombreConfiguracionesBaseDeDatosAdjuntas	Nombre del objeto de configuraciones de base de datos adjuntas. El nombre puede ser cualquier cadena que sea única en el nivel de clúster.
   databaseName	Nombre de la base de datos que se va a monitorizar. Para seguir todas las bases de datos del líder, use "*".
   leaderClusterResourceId	Identificador de recurso del clúster líder.
   defaultPrincipalsModificationKind	Tipo de modificación de principal predeterminada.	Puede ser Union, Replace o None. Para obtener más información sobre el tipo de modificación del principal predeterminado, consulte el comando de control del tipo de modificación del principal.
   tablasParaIncluir	Lista de tablas que se van a incluir. Para incluir todas las tablas a partir de "Logs", use ["Logs*"].	["table1ToInclude", "table2ToInclude"]
   tablesToExclude	Lista de tablas que se van a excluir. Para excluir todas las tablas, use ["*"].	["table1ToExclude", "table2ToExclude"]
   externalTablesToInclude	Lista de tablas que se van a incluir. Para incluir todas las tablas externas que comienzan con "Logs", use ["Logs*"].	["ExternalTable1ToInclude", "ExternalTable2ToInclude"]
   externalTablesToExclude	Lista de tablas que se van a excluir. Para excluir todas las tablas externas, use ["*"].	["ExternalTable1ToExclude", "ExternalTable2ToExclude"]
   materializedViewsToInclude	Lista de vistas materializadas que se van a incluir. Para incluir todas las vistas materializadas que empiecen con "Registros", use ["Registros*"].	["Mv1ToInclude", "Mv2ToInclude"]
   vistasMaterializadasParaExcluir	Lista de vistas materializadas que deben excluirse. Para excluir todas las vistas materializadas, use ["*"].	["Mv11ToExclude", "Mv22ToExclude"]
   funcionesParaIncluir	Lista de funciones que se van a incluir.	["FunctionToInclude"]
   functionsToExclude	Lista de funciones que se van a excluir.	["FunctionToExclude"]
   ubicación	Ubicación de todos los recursos. El líder y el seguidor deben estar en la misma ubicación.
