uploaded

void uploaded(long timeTaken,
              java.util.concurrent.TimeUnit unit,

timeTaken - time taken to perform the operation

unit - unit of time taken

size - size of binary content being read

uploadCompleted

void uploadCompleted(java.lang.String blobId)

Invoked when upload for a binary file get completed. In case of chunked BlobStore this invoked when all the chunks have been uploaded
