Configurar ingestão de streaming no cluster do Azure Data Explorer

Ao criar um cluster usando as etapas em Criar um cluster e um banco de dados do Azure Data Explorer, na guia Configurações, selecione Ingestão de streaming>Ativada.

Para habilitar a ingestão de streaming ao criar um cluster do Azure Data Explorer, execute o seguinte código:

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. No portal do Azure, acesse o cluster do Azure Data Explorer.

2. Em Configurações, selecione Configurações.

3. No painel Configurações, selecione Ativado para habilitar a Ingestão de streaming.

4. Selecione Salvar.

   

Você pode habilitar a ingestão de streaming ao atualizar um cluster existente do Azure Data Explorer.

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. No portal do Azure, navegue até o cluster.

2. Selecione Consulta.

   

3. Para criar a tabela que receberá os dados usando a ingestão de streaming, copie o comando a seguir no painel Consulta e selecione Executar.

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

   

4. Copie um dos comandos a seguir no painel Consulta e selecione Executar. Isso define a política de ingestão de streaming na tabela criada ou no banco de dados que contém a tabela.

   Dica

   Uma política definida no nível do banco de dados se aplica a todas as tabelas existentes e futuras no banco de dados. Quando você habilita a política no nível do banco de dados, não é necessário habilitá-la por tabela.

   • Para definir a política na tabela que você criou, use:

     .alter table TestTable policy streamingingestion enable
     

   • Para definir a política no banco de dados que contém a tabela que você criou, use:

     .alter database StreamingTestDb policy streamingingestion enable
