> S3 File Reader reading more data than expected
> ----------------------------------------------

> Key: APEXMALHAR-2174

> Project: Apache Apex Malhar
> Issue Type: Bug
> Reporter: Chaitanya

> This is observed through the AWS billing.
> Issue might be the S3InputStream.read() which is used in readEntity().
> Reading the block can be achieved through the AmazonS3 api's. So, I am
> proposing the following solution:
> ```
> GetObjectRequest rangeObjectRequest = new GetObjectRequest(
> bucketName, key);
> rangeObjectRequest.setRange(startByte, noOfBytes);
> S3Object objectPortion = s3Client.getObject(rangeObjectRequest);
> S3ObjectInputStream wrappedStream = objectPortion.getObjectContent();
> byte[] record = ByteStreams.toByteArray(wrappedStream);
> Advantages of this solution: Parallel read will work for all types of s3 file
> systems.
