Add support for automatic chunked upload/download with server-side merging

I would like to sincerely suggest the addition of a feature that supports automatic chunked upload and download for large files, with merging handled on the server side. This approach—commonly used across cloud platforms such as AWS S3 multipart upload and Google Cloud Storage—offers greater reliability and scalability, especially when handling large files. Ideally, the system would: Automatically divide large files into smaller chunks (e.g. 4~50MB) Upload or download these chunks in sequence or in parallel Merge them server-side, rather than relying on the client to reassemble Provide checksum verification for data integrity Support resumable transfers for better fault tolerance This would be highly valuable for applications involving video uploads, software distribution, backups, or any case requiring efficient large file handling. I truly believe this enhancement would benefit many developers and improve the overall developer experience on your platform. Thank you for considering it.
