In TOS, the basic unit of data storage is a file. The TOS Python SDK provides a rich way to upload objects.
Upload method description
- Normal Upload (Python SDK): Upload object size does not exceed 5GiB, support progress bar, client side speed limit.
- Append Upload (Python SDK): The size of the added object cannot be greater than 5GiB, and supports progress bars and client side speed limits.
- Shard Upload (Python SDK): Except for the last sharding, other sharding sizes need to be greater than or equal to 5MiB, the number range of the uploaded sharding is [1,10000], and it supports progress bars and client side speed limits.
- Breakpoint Resumption (Python SDK): Support concurrency, breakpoint continuation, custom sharding size, event callback, progress bar, cancellation mechanism, this interface is recommended for large file uploads.
