减少 verbosity/frequency 的 Amazon S3 AWS 上传 ProgressListener？

Question

我正在将多部分文件上传到 S3。我添加了一个 ProgressListener 来打印进度，效果很好。太棒了。我上传的文件有几 GB 大，我记录的消息过于细化。我得到了几千个这样的东西：

2021-11-04 06:56:07 INFO  GenericSftpLoader:190 - transfered bytes: 8192

有什么方法可以减少每 8192 字节打印一次，而是打印出更合理的内容，例如 1048576 字节吗？

我的实际代码是在 Scala 中，但我密切关注 this example AWS SDK 文档：

TransferManager tm = new TransferManager(new ProfileCredentialsProvider());        

    PutObjectRequest request = new PutObjectRequest(
            existingBucketName, keyName, new File(filePath));
    
    request.setGeneralProgressListener(new ProgressListener() {
        @Override
        public void progressChanged(ProgressEvent progressEvent) {
            System.out.println("Transferred bytes: " + 
                    progressEvent.getBytesTransferred());
        }
    });       

    Upload upload = tm.upload(request);

所以我得到了解决方案。这是我所做的：

TransferManager tm = new TransferManager(new ProfileCredentialsProvider());

PutObjectRequest request = new PutObjectRequest(
        existingBucketName, keyName, new File(filePath));

request.setGeneralProgressListener(new ProgressListener() {
    private Long myBytes = 0
    @Override
    public void progressChanged(ProgressEvent progressEvent) {
        myBytes += progressEvent.getBytesTransferred();
        if (bytesTransferred > 1048576) {
            System.out.println("Transferred bytes: " + 
                    myBytes);
            myBytes = 0;
        }
    }
});       

Upload upload = tm.upload(request);
