UpdateJobPriority与 AWS SDK 或 CLI 配合使用

更新 Amazon S3 批量操作任务的任务优先级

以下 update-job-priority 示例会将指定的任务更新为新的优先级。

aws s3control update-job-priority \
    --account-id 123456789012 \
    --job-id 8d9a18fe-c303-4d39-8ccc-860d372da386 \
    --priority 52

输出：

{
    "JobId": "8d9a18fe-c303-4d39-8ccc-860d372da386",
    "Priority": 52
}
