减少亚马逊S3 AWS上传ProgressListener的冗长/频率

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，而且我记录的消息太细了。我收到了几千个这样的：

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

有没有什么方法可以减少这种情况，从每8192个字节打印一次，改为更合理的1048576个字节？

我的实际代码是在Scala中编写的，但我密切关注AWS SDK文档中的这个例子：

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);

Answer 1

所以我得到了一个解决方案。以下是我所做的：

TransferManager tm=新的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);
