This code will using Python multithreading to upload multiple part of the file simultaneously as any modern download manager will do using the feature of HTTP/1.1. One last thing before we finish and test things out is to flush the sys resource so we can give it back to memory: Now were ready to test things out. S3 Multipart upload doesn't support parts that are less than 5MB (except for the last one). This is useful when you are dealing with multiple buckets st same time. This code will using Python multithreading to upload multiple part of the file simultaneously as any modern download manager will do using the feature of HTTP/1.1. Now, for all these to be actually useful, we need to print them out. Amazon Simple Storage Service (S3) can store files up to 5TB, yet with a single PUT operation, we can upload objects up to 5 GB only. bucket.upload_fileobj (BytesIO (chunk), file, Config=config, Callback=None) Amazon suggests, for objects larger than 100 MB, customers should consider using the Multipart Upload capability. response = s3.complete_multipart_upload( Bucket = bucket, Key = key, MultipartUpload = {'Parts': parts}, UploadId= upload_id ) 5. Now create S3 resource with boto3 to interact with S3: For example, a 200 MB file can be downloaded in 2 rounds, first round can 50% of the file (byte 0 to 104857600) and then download the remaining 50% starting from byte 104857601 in the second round.
