Konfigurace příjmu streamování v clusteru Azure Průzkumník dat

Při vytváření clusteru pomocí postupu v části Vytvoření clusteru a databáze Azure Průzkumník datklikněte na kartě Konfigurace na možnost ingestování streamování.

Pokud chcete povolit přijímání streamování při vytváření nového clusteru Azure Průzkumník dat, spusťte následující kód:

using System.Threading.Tasks;
using Microsoft.Azure.Management.Kusto; // Required package Microsoft.Azure.Management.Kusto
using Microsoft.Azure.Management.Kusto.Models;
using Microsoft.IdentityModel.Clients.ActiveDirectory; // Required package Microsoft.IdentityModel.Clients.ActiveDirectory
using Microsoft.Rest;
namespace StreamingIngestion
{
    class Program
    {
        static async Task Main(string[] args)
        {
            string appId = "<appId>";
            string appKey = "<appKey>";
            string appTenant = "<appTenant>";
            string clusterName = "<clusterName>";
            string resourceGroupName = "<resourceGroupName>";
            string subscriptionId = "<subscriptionId>";
            string location = "<location>";
            string skuName = "<skuName>";
            string tier = "<tier>";

            var authenticationContext = new AuthenticationContext($"https://login.windows.net/{appTenant}");
            var credential = new ClientCredential(appId, appKey);
            var result = await authenticationContext.AcquireTokenAsync(resource: "https://management.core.windows.net/", clientCredential: credential);

            var credentials = new TokenCredentials(result.AccessToken, result.AccessTokenType);
            var kustoManagementClient = new KustoManagementClient(credentials)
            {
                SubscriptionId = subscriptionId
            };

            var cluster = new Cluster(location, new AzureSku(skuName, tier), enableStreamingIngest:true);
            await kustoManagementClient.Clusters.CreateOrUpdateAsync(resourceGroupName, clusterName, cluster);
        }
    }
}

1. V Azure Portal přejdete do svého clusteru Azure Průzkumník dat.

2. v Nastavenívyberte konfigurace.

3. V podokně Konfigurace vyberte zapnuto , aby se povolilo přijímání streamování.

4. Vyberte Uložit.

   

Při vytváření nového clusteru Azure Průzkumník dat můžete povolit přijímání streamování.

    }
}

1. V Azure Portal přejděte na svůj cluster.

2. Vyberte dotaz.

   

3. Chcete-li vytvořit tabulku, která bude přijímat data prostřednictvím příjmu streamování, zkopírujte následující příkaz do podokna dotazu a vyberte Spustit.

   .create table TestTable (TimeStamp: datetime, Name: string, Metric: int, Source:string)
   

   

4. Zkopírujte jeden z následujících příkazů do podokna dotazu a vyberte Spustit. Tím se definuje zásada pro přijímání streamování v tabulce, kterou jste vytvořili, nebo v databázi obsahující tabulku.

   Tip

   Zásada definovaná na úrovni databáze se vztahuje na všechny existující a budoucí tabulky v databázi.

   • Pro definování zásad pro tabulku, kterou jste vytvořili, použijte:

     .alter table TestTable policy streamingingestion enable
     

   • Pro definování zásad pro databázi obsahující tabulku, kterou jste vytvořili, použijte:

     .alter database StreamingTestDb policy streamingingestion enable

1. V Azure Portal přejděte do svého clusteru Azure Data Explorer a vyberte Dotaz.

2. Pokud chcete z tabulky vypustit zásady příjmu streamování, zkopírujte následující příkaz do podokna Dotazu a vyberte Spustit.

   .delete table TestTable policy streamingingestion
   

   

3. V Nastavenívyberte Konfigurace.

4. V podokně Konfigurace vyberte Vypnuto a zakažtepříjem dat streamování.
