title: Amazon S3 copying multiple files from one bucket to another
body: <p>I have a large list of objects in source S3 bucket and i selectively want to copy a subset of objects in to destination bucket.
  As per <a href="https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/examples-s3-transfermanager.html" rel="nofollow noreferrer">doc</a> here it seems its possible with <code>TransferManager.copy(from_bucket, from_key, to_bucket, to_key)</code>, however i need to do it one at a time.</p>
  
  <p>Is anyone aware of other ways, preferably to copy in a batched fashion instead of calling copy() for each object ?</p>
