What is the fastest way to delete a large number of files stored in Alibaba Cloud OSS?

Using a lifecycle rule to delete files after a specified time is an efficient and automated approach when managing large numbers of files in Alibaba Cloud Object Storage Service (OSS). Setting a lifecycle rule allows users to define criteria under which files will be automatically deleted or transitioned to a lower-cost storage class after a certain period.

This method is particularly advantageous for handling large datasets, as it minimizes manual intervention and can help in managing storage costs over time. Once configured, the lifecycle rule operates in the background, removing the need for ongoing monitoring and manual deletions, making it a time-saving solution.

In contrast, manually deleting files via the Web Console can be cumbersome and time-consuming, especially for large volumes, as it requires significant interaction and is prone to human error. Running a script can also be effective; however, it requires knowledge of programming and the OSS API. Archiving files, instead of deleting them, may make sense for data retention but does not directly address the need for prompt deletion of files in a scenario where freeing up storage space is the priority.
