To manage large file uploads to S3 without blocking, use multipart uploads with presigned URLs. This method offloads data transfer to the client, reducing server load and ensuring scalable file ingestion.

The best way to securely distribute presigned URLs for cloud storage is to apply strict input validation when generating them. This ensures safe presigned URL distribution while preventing unauthorized access to your S3 or Cloudflare R2 buckets.

Yes, you can use Cloudflare R2 integration with multipart uploads and image optimization. This combination allows you to handle large files efficiently and process images without blocking your web service operations.

Presigned URLs reduce server load by enabling client-side uploads directly to cloud storage like S3 or Cloudflare R2. This bypasses the server during file transfer, preventing network blocking and improving application performance.

When using multipart uploads for large files, you must ensure secure input validation and correct handling of each part. Limitations include the complexity of managing interrupted uploads and the need to safely distribute presigned URLs for each segment.
