S3 TransferListener Progress percent not work properly when uploading byte arrays

[JmKanmo]

Describe the bug

0.0 => 100.0% => (4min 25sec later) => Transfer complete!

It didn't show process percent gradually.

Expected Behavior

Below code is s3 file download. It work properly.

When uploading byte arrays

 UploadRequest uploadRequest = UploadRequest.builder()
                .putObjectRequest(b -> b.bucket(WHATAP_AWS_BUCKET_NAME).key(WHATAP_DESTINATION_KEY))
                .addTransferListener(LoggingTransferListener.create())
                .requestBody(AsyncRequestBody.fromBytes(originBytes))
                .build();

It need to fix this bug.

[JmKanmo]

I think the current TransferListener is monitoring the progress of the conversion from File -> byte array.

Therefore, when uploading a byte array, 0.0% => 100% => after a while -> completed as shown above.

When uploading with Paths.get(dir), the progress is monitored as 0.0% => 32.6% => 65.3% => 98.0% => 100.0% => after a while => completed.

Users using s3 uploads/downloads want to see the full progress of the final upload to s3, not the file->to-byte-array conversion. The above matters are judged to need improvement. So, please work on improving the request.

Transferring to the Java SDK v2 repo.

I think we got a previous report of this same issue but I couldn't find it here...

[debora-ito]

Found it - https://github.com/aws/aws-sdk-java-v2/issues/3670.

@JmKanmo I'll keep this open too, since you provided a lot of repro steps.

[leo-hydraulic]

I believe we hit this bug as well.

What we observe when uploading a file is this: TransferListener.bytesTransferred gets called with increasing values in rapid succession: 0.0% => 32.6% => 65.3% => 98.0% => 100.0%

After we've already reached 100%, minutes pass without any calls to TransferListener.bytesTransferred.

Presumably the real transfer happens during this long pause.

Finally the transfer ends.

It seems, as someone pointed out in a previous comment, that the progress being tracked is for transferring bytes from the file into some memory buffer, not transferring them to S3.

NB: We're uploading a file, not a byte array.
