问题
I am trying to upload huge files to S3 using BufferedInputStream and providing it with a Buffer size of 5MB but the performance of the application is hindered because of the network speed/amount the available data to read is limited like mentioned in this answer link (limited to 1MB). This makes me upload 1MB as part size at a time to s3 using UploadPartRequest which increases my time to upload. So, is there any other better and fast way to upload to S3 using FileInputStream as a source.
Is it possible that I can wait until my bytes read is equal to buffer size then upload the part? will it increase the speed of upload?
