using Azure;
using Azure.Core;
using Azure.Identity; // Required package Azure.Identity
using Azure.ResourceManager;
using Azure.ResourceManager.Kusto; // Required package Azure.ResourceManager.Kusto

{
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);
}
}

クラスターでストリーミング インジェストを無効にする
警告
ストリーミング インジェストの無効化には数時間かかることがあります。
Azure Data Explorer クラスターでストリーミング インジェストを無効にする前に、関連するすべてのテーブルとデータベースからストリーミング インジェスト ポリシーを削除します。 ストリーミング インジェスト ポリシーを削除すると、Azure Data Explorer クラスター内でデータの再配置がトリガーされます。 ストリーミング インジェストのデータは、初期ストレージから列ストア (エクステントまたはシャード) 内の永続的なストレージへ移動されます。 初期ストレージ内のデータ量によっては、このプロセスに数秒から数時間かかることがあります。
using System.Threading.Tasks;
using Kusto.Data; // Requires Package Microsoft.Azure.Kusto.Data
using Kusto.Data.Common;
using Kusto.Data.Net.Client;
