FAQ
Questions S3 Multipart Calculator owners ask.
- 01
How do I know if my part size is valid?
The calculate_upload_plan capability will automatically check if your part size is at least 5 MB and if the total part count stays within the 10,000 limit, providing validation flags if they are not.
- 02
Can I optimize for specific network speeds?
Yes, you can use recommend_optimal_configuration by providing your available bandwidth in Mbps to receive a suggested part size that balances API overhead and retry costs.
- 03
How can I prevent costs from failed uploads?
Use get_lifecycle_and_integrity_policy to generate an S3 lifecycle rule that automatically aborts incomplete multipart uploads after a specified number of days.
