Objects are the basic unit for data operations in Object Storage Service (OSS). OSS SDK for C++ provides the following methods to upload objects:
Simple upload: supports the upload of an object that is up to 5 GB in size. It supports upload from memory and local storage.
Append upload: supports the upload of an object that is up to 5 GB in size.
Resumable upload: supports the upload of an object that is up to 48.8 TB in size. This method is suitable for uploading large objects. Concurrent upload is supported. You can specify the size of parts.
Multipart upload: supports the upload of an object that is up to 48.8 TB in size. This method is suitable for uploading large objects.
During the upload, you can specify object metadata and view the upload progress. For more information, see Manage object metadata and Progress bar. After the upload is complete, you can receive callbacks. For more information, see Upload callbacks.
