포함할 객체 선택 섹션에서 포함할 객체 드롭다운 메뉴를 사용하여 Datastream이 대상으로 전송할 소스 데이터베이스의 테이블과 스키마를 변경합니다.
필요에 따라 제외할 객체 선택 노드를 확장합니다. 제외할 객체 필드에서 Datastream이 대상으로 전송하지 못하도록 제한할 소스 데이터베이스의 테이블 및 스키마를 수정합니다. 이 목록에 테이블이 추가되면 더 이상 대상에 가져오지 않습니다. 하지만 대상에서 삭제되지는 않습니다.
Oracle 소스의 경우 CDC 메서드를 수정할 수 없습니다. 하지만 이 로그 파일 액세스 유형을 선택한 경우 데이터베이스 디렉터리 세부정보를 변경할 수 있습니다.
필요한 경우 이전 데이터의 백필 모드 선택 노드를 확장하여 Datastream이 소스의 현재 및 미래 데이터로 대상을 백필할지 또는 이 데이터의 변경사항만 스트리밍할지 여부를 수정합니다.
데이터 변경사항 외에도 소스에서 대상으로 모든 기존 데이터를 스트리밍하려면 자동 옵션을 선택합니다.
이 옵션을 선택하면 자동 백필에서 제외된 객체 필드에서 Datastream이 대상에 백필하지 못하도록 제한할 소스 데이터베이스의 테이블 및 스키마를 수정할 수 있습니다.

Datastream uses this configuration information to transfer the correct data from the source database to the destination.\n\n | **Note:** You can't change the source database type for an already created stream. To change the database type, you need to create a new stream. For more information, see [Create a stream](/datastream/docs/create-a-stream).\n\nModify high-level information\n-----------------------------\n\n1. Go to the **Streams** page in the Google Cloud Console.\n\n [Go to the Streams page](https://console.cloud.google.com/datastream/streams)\n2. Click the stream that you want to modify.\n\n3. On the **Stream details** page, click **EDIT**.\n\n4. Select **Edit stream settings** from the menu that appears.\n\n5.

On the **Stream details** page, click **EDIT**.\n\n4. Select **Edit source configuration** from the menu that appears.\n\n5. In the **Select objects to include** section, use the **Objects to include** drop-down menu to change the tables and schemas in the source database that Datastream will transfer to the destination.\n\n6. Optionally, expand the **Select objects to exclude** node. In the **Objects to exclude** field, modify the tables and schemas in the source database that you want to restrict Datastream from transferring into the destination. If tables are added to this list, then they're no longer pulled into the destination. However, they're not removed from the destination.\n\n | For more information about the **Objects to include** menu or the **Objects to exclude** field, see [Configure information about the source database for the stream](/datastream/docs/create-a-stream#configuresourcedbinfo).\n\n \u003cbr /\u003e\n\n7. Note that for Oracle sources, you can't modify the CDC method. However, you can change the database directories details, if you selected this log file access type.\n\n8. Optionally, expand the **Choose backfill mode for historical data** node to modify whether Datastream backfills the destination with current and future data from the source, or streams only changes to this data.\n\n - Select the **Automatic** option to stream all existing data, in addition to changes to the data, from the source into the destination.\n\n If you select this option, then in the **Objects excluded from automatic backfill** field, you can modify the tables and schemas in the source database that you want to restrict Datastream from backfilling into the destination.\n - Select the **Manual** option to stream only changes to the data.\n\n | For more information about the **Choose backfill mode for historical data** node, see [Configure information about the source database for the stream](/datastream/docs/create-a-stream#configuresourcedbinfo).\n9.

On the **Stream details** page, click **EDIT**.\n\n4. Select **Edit destination configuration** from the menu that appears.\n\n5. Depending on the destination that you selected, adjust the following settings as required:\n\n **BigQuery** destinations:\n - Under **Encryption**, change the type of encryption that you want to use: Google-managed encryption key or Cloud Key Management Service key.\n - Under **Balance data staleness and BigQuery costs** , change the **Staleness limit** option.\n\n **BigLake Iceberg tables** destinations:\n - Under **Encryption**, change the type of encryption that you want to use: Google-managed encryption key or Cloud Key Management Service key.\n\n **Cloud Storage** destinations:\n - In the **Stream path prefix** field, modify the folder of the destination into which Datastream will transfer schemas, tables, and data from the source database. If you change the folder, then all new files will be written to the new folder. Also, for more information about the **Stream path prefix** field, see [Configure information about the destination for the stream](/datastream/docs/create-a-stream#configuredestinfo).\n - From the **Output format** menu:\n - Choose the format of files written to Cloud Storage. Datastream supports two output formats: Avro and JSON.\n - If you select the JSON format, then select or clear the **Include a Unified Types schema file in the file path** and **Enable gzip compression** check boxes. For more information about these check boxes, see [Configure information about the destination for the stream](/datastream/docs/create-a-stream#configuredestinfo).\n6. Click **SAVE** to apply your changes and [start your stream](/datastream/docs/run-a-stream#startastream). Any modifications that you make to streams that are running are updated by Datastream automatically.\n\nWhat's next\n-----------\n\n- To learn more about streams, see [Stream lifecycle](/datastream/docs/stream-states-and-actions).\n- To learn how to monitor a stream, see [Monitor a stream](/datastream/docs/monitor-a-stream).\n- To learn how to view information about your stream, see [View a stream](/datastream/docs/view-a-stream).\n- To learn how to recover a failed stream, see [Recover a stream](/datastream/docs/recover-a-stream).\n- To learn how to delete an existing stream, see [Delete a stream](/datastream/docs/delete-a-stream)."]]
