# 如何在 Amazon Keyspaces 中存取 CDC 串流端點
<a name="CDC_access-endpoints"></a>

Amazon Keyspaces 會在提供 Amazon Keyspaces AWS 區域 的每個 中維護金鑰空間/資料表和 CDC 串流的個別[端點](programmatic.endpoints.md#global_endpoints)。若要存取 CDC 串流，請選取資料表的區域，並將端點名稱`cassandra-streams`中的`cassandra`字首取代為 ，如下列範例所示：


| 區域名稱 | 區域 | 金鑰空間和資料表的端點 | 串流的端點 | 
| --- | --- | --- | --- | 
| 美國東部 (維吉尼亞北部) | us-east-1 | {{cassandra}}.us-east-1.api.aws | {{cassandra-streams}}.us-east-1.api.aws | 

下表包含 可用的公有端點完整清單 Amazon Keyspaces change data capture streams。 同時 Amazon Keyspaces CDC streams 支援 IPv4 和 IPv6。所有公有端點，例如 `cassandra-streams.us-east-1.api.aws`，都是可針對 IPv4 和 IPv6 設定的雙堆疊端點。
