What is the most efficient method for handling temporary files in a Function Compute function that requires around 1 GB of temporary storage?

Using an OSS bucket with a lifecycle policy configured to delete temporary files automatically is an efficient method for handling temporary files in a Function Compute environment. This approach leverages AliCloud's Object Storage Service (OSS), which is designed to store large amounts of data and provides robust management features, including lifecycle policies.

When temporary files are copied to the OSS bucket, they can benefit from scalability and redundancy—features that are essential when dealing with significant data sizes. By setting up a lifecycle policy, you ensure that these temporary files are automatically cleaned up after a specified time or under certain conditions, which reduces the risk of manually managing storage and prevents unnecessary costs associated with retaining data that is no longer needed.

In contrast, using local storage might limit the amount of available storage due to the constrained environment of Function Compute, especially since the function may run on instances with limited ephemeral storage. Leaving files on the executed server could result in unmonitored accumulation of data, leading to potential resource waste and increasing management overhead. Lastly, compressing files could save space, but it does not inherently solve the issue of efficiently managing temporary storage nor does it provide a mechanism for automatic deletion once the function processing is complete. Thus, using OSS for temporary storage not only simplifies file management but also
