Multipart upload

The S3 protocol allows you to upload a large file as multiple parts rather than as a single request.

The client initiates a multipart upload with a POST request with the uploads the query parameter and the object key. On the cluster, a unique userUploadId string is generated by concatenating the bucket ID and upload ID and returned to the client. The pair of bucket ID and upload ID is also stored in a per-zone SBT. A directory, .s3_parts_userUploadID is created in the target directory to store the parts. After getting created, the directory and kvstore entry persists until the multipart operation is either completed or stopped. Parts are uploaded with a part number and stored in the temporary directory. A part has a maximum size of 5 GB and the last part a minimum size of 5 MB. Complete multipart upload is handled by concatenating the parts to a temporary file under the .isi_s3 directory. Once the concatenation succeeds, the temporary file is copied to the target, the .s3_parts_userUploadID is deleted, and the SBT entry is removed.
