Fragment Management
Last Updated：2021-09-30
Overview
During the multi-part upload, the file (Object) is split into multiple parts. These parts are called fragments. When you upload these parts to BOS, you can call CompleteMultipartUpload to combine these fragments (Parts) into a complete Object. Part is produced during the multi-part upload. For details, see Object Multipart Upload
Considerations
- During the Part existence, the bucket capacity should be calculated for billing.
- You can also call CompleteMultipartUpload to combine these fragments (Parts) into a complete Object. For details about the use of MultipartUpload, see Brief Introductions.
- You can also clear the unwanted Parts on a regular basis by setting the lifetime. Also, you can perform this configuration to clear the Parts that fail to go through the CompleteMultipartUpload process in the Bucket for a long period, saving the space storage capacity. For particular operations, see [Set Lifetime Rules](BOS/Console Operation Guide/Manage Bucket/).
- After the combination of the Parts into a complete Object, you cannot read them.
- During the deletion of the Bucket, must delete the Object and Part. The fragment is produced by the multipart upload. For details, see Object Multipart Upload..
