Multipart upload implementation process?

Can you tell me: the slice upload is a client-side shard upload, after the upload is completed on the server end merge? If half of the upload, broken network, the next time to enter the application should be how to deal with it?

One of our previous projects was to invoke the Amazon S3 multipart upload interface to implement file upload functionality.
Answer your two questions accordingly:

1. The process of merging shards is, of course, done on the server side.

2. If I remember correctly, after the network is broken after the server timeout after the upload will fail, cannot continue to pass. However, the continuation of the breakpoint is completely achievable, as long as you do not delete the previous shard is OK.
