feat: use transfer manager for parallel S3 snapshot downloads#27
Conversation
Replace the single-stream s3.GetObject with the transfer manager GetObject for snapshot restores. The transfer manager downloads byte ranges in parallel via a concurrentReader and reassembles them into a sequential io.Reader, giving us parallel throughput without needing a temp file or changing the streaming extraction pipeline.
