檢視串流的標籤

使用 CQL 檢視串流的標籤

若要讀取連接至串流的標籤，您必須在 WHERE子句中指定串流的資源 ARN。下列 CQL 語法為範例。

SELECT * FROM system_schema_mcs.tags WHERE resource_id = stream_arn;

• 下列查詢會傳回指定串流的標籤。

  SELECT tags FROM system_schema_mcs.tags WHERE resource_id = 'arn:aws:cassandra:aws-region:111122223333:/keyspace/my_keyspace/table/my_table/stream/2025-05-06T17:17:39.800';

  該查詢的輸出如下所示。

   resource_id                                                                                                       | keyspace_name | resource_name           | resource_type | tags   
   ------------------------------------------------------------------------------------------------------------------+---------------+-------------------------+---------------+---------------------- 
   arn:aws:cassandra:aws-region:111122223333:/keyspace/my_keyspace/table/my_table/stream/2025-04-02T23:00:07.052     |      singleks | 2025-04-02T23:00:07.052 |        stream | {'tagkey': 'tagval'}  

使用 檢視串流的標籤 AWS CLI

• 此範例說明如何列出指定金鑰空間下所有串流的標籤。

  aws keyspaces list-tags-for-resource --resource-arn 'arn:aws:cassandra:aws-region:111122223333:/keyspace/my_keyspace/table/my_table/stream/2025-05-11T21:21:33.291'

  最後一個命令的輸出如下所示。

  {
      "tags": [
          {
              "key": "key1",
              "value": "val1"
          },
          {
              "key": "key2",
              "value": "val2"
          },
          {
              "key": "key3",
              "value": "val3"
          },
          {
              "key": "key4",
              "value": "val4"
          }
      ]
  }
