Mengonfigurasi penyerapan streaming di kluster Azure Data Explorer Anda

Saat membuat kluster menggunakan langkah-langkah dalam Membuat kluster dan database Azure Data Explorer, di tab Konfigurasi, pilih Streaming penyerapan>Aktif.

Untuk mengaktifkan penyerapan streaming saat membuat kluster Azure Data Explorer baru, jalankan kode berikut:

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. Di portal Azure, buka kluster Azure Data Explorer Anda.

2. Pada Pengaturan, pilih Konfigurasi.

3. Di panel Konfigurasi, pilih Terus untuk mengaktifkan konsumsi Streaming.

4. Pilih Simpan.

   

Anda dapat mengaktifkan penyerapan streaming saat memperbarui kluster Azure Data Explorer yang ada.

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. Di portal Azure, buka kluster Anda.

2. Pilih Kueri.

   

3. Untuk membuat tabel yang akan menerima data melalui konsumsi streaming, salin perintah berikut ke panel Kueri dan pilih Jalankan.

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

   

4. Salin salah satu perintah berikut ke panel Kueri dan pilih Jalankan. Ini mendefinisikan kebijakan konsumsi streaming pada tabel yang Anda buat atau pada database yang berisi tabel.

   Tip

   Kebijakan yang didefinisikan pada tingkat database berlaku untuk semua tabel yang ada dan masa depan dalam database. Saat Anda mengaktifkan kebijakan di tingkat database, tidak perlu mengaktifkannya per tabel.

   • Untuk menentukan kebijakan pada tabel yang Anda buat, gunakan:

     .alter table TestTable policy streamingingestion enable
     

   • Untuk menentukan kebijakan pada database yang berisi tabel yang Anda buat, gunakan:

     .alter database StreamingTestDb policy streamingingestion enable

   .delete table TestTable policy streamingingestion
   

   

3. Pada Pengaturan, pilih Konfigurasi.

4. Di panel Konfigurasi, pilih Terus untuk mengaktifkan konsumsi Streaming.

5. Pilih Simpan.
