Konfigurieren der Streamingerfassung in Ihrem Azure Data Explorer-Cluster

Während Sie einen Cluster anhand der Schritte unter Schnellstart: Erstellen eines Azure Data Explorer-Clusters und einer Datenbank erstellen, wählen Sie auf der Registerkarte Konfigurationen die Option Streamingerfassung>Ein.

Führen Sie zum Aktivieren der Streamingerfassung während der Erstellung eines neuen Azure Data Explorer-Clusters den folgenden Code aus:

using System.Threading.Tasks;
using Azure;
using Azure.Core;
using Azure.Identity; // Required package Azure.Identity
using Azure.ResourceManager;
using Azure.ResourceManager.Kusto; // Required package Azure.ResourceManager.Kusto
using Azure.ResourceManager.Kusto.Models;
namespace StreamingIngestion;
class Program
{
    static async Task Main(string[] args)
    {
        var appId = "<appId>";
        var appKey = "<appKey>";
        var appTenant = "<appTenant>";
        var subscriptionId = "<subscriptionId>";
        var credentials = new ClientSecretCredential(appTenant, appId, appKey);
        var resourceManagementClient = new ArmClient(credentials, subscriptionId);
        var resourceGroupName = "<resourceGroupName>";
        var clusterName = "<clusterName>";
        
        var subscription = await resourceManagementClient.GetDefaultSubscriptionAsync();
        var resourceGroup = (await subscription.GetResourceGroupAsync(resourceGroupName)).Value;
        var clusters = resourceGroup.GetKustoClusters();
        
        var location = new AzureLocation("<location>");
        var skuName = new KustoSkuName("<skuName>");
        var skuTier = new KustoSkuTier("<skuTier>");
        var clusterData = new KustoClusterData(location, new KustoSku(skuName, skuTier)) { IsStreamingIngestEnabled = true };
        await clusters.CreateOrUpdateAsync(WaitUntil.Completed, clusterName, clusterData);
    }
}

1. Navigieren Sie im Azure-Portal zum Azure Data Explorer-Cluster.

2. Wählen Sie unter Einstellungen die Option Konfigurationen aus.

3. Wählen Sie im Bereich Konfigurationen die Option Ein aus, um die Streamingerfassung zu aktivieren.

4. Wählen Sie Speichern.

   

Sie können die Streaming-Eingabe beim Aktualisieren eines vorhandenen Azure-Data-Explorer-Clusters aktivieren.

using System.Threading.Tasks;
using Azure;
using Azure.Identity; // Required package Azure.Identity
using Azure.ResourceManager;
using Azure.ResourceManager.Kusto; // Required package Azure.ResourceManager.Kusto
using Azure.ResourceManager.Kusto.Models;
namespace StreamingIngestion;
class Program
{
    static async Task Main(string[] args)
    {
        var appId = "<appId>";
        var appKey = "<appKey>";
        var appTenant = "<appTenant>";
        var subscriptionId = "<subscriptionId>";
        var credentials = new ClientSecretCredential(appTenant, appId, appKey);
        var resourceManagementClient = new ArmClient(credentials, subscriptionId);
        var resourceGroupName = "<resourceGroupName>";
        var clusterName = "<clusterName>";
        var subscription = await resourceManagementClient.GetDefaultSubscriptionAsync();
        var resourceGroup = (await subscription.GetResourceGroupAsync(resourceGroupName)).Value;
        var cluster = (await resourceGroup.GetKustoClusterAsync(clusterName)).Value;
        var clusterPatch = new KustoClusterPatch(cluster.Data.Location) { IsStreamingIngestEnabled = true };
        await cluster.UpdateAsync(WaitUntil.Completed, clusterPatch);
    }
}

1. Navigieren Sie im Azure-Portal zu Ihrem Cluster.

2. Wählen Sie Abfrage aus.

   

3. Kopieren Sie den folgenden Befehl in den Abfragebereich, und wählen Sie Ausführen aus, um die Tabelle zu erstellen, die die Daten über Streamingerfassung erhalten soll:

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

   

4. Kopieren Sie einen der folgenden Befehle in den Abfragebereich, und wählen Sie Ausführen aus: Dadurch wird die Streamingerfassungsrichtlinie für die von Ihnen erstellte Tabelle oder für die Datenbank definiert, die diese Tabelle enthält.

   Tipp

   Eine Richtlinie, die auf Datenbankebene definiert ist, gilt für alle vorhandenen und zukünftigen Tabellen in der Datenbank. Wenn Sie die Richtlinie auf Datenbankebene aktivieren, müssen Sie sie nicht pro Tabelle aktivieren.

   • Verwenden Sie Folgendes, um die Richtlinie für die von Ihnen erstellte Tabelle zu definieren:

     .alter table TestTable policy streamingingestion enable
     

   • Verwenden Sie Folgendes, um die Richtlinie für die Datenbank zu definieren, die die von Ihnen erstellte Tabelle enthält:

     .alter database StreamingTestDb policy streamingingestion enable
