Sneha, What are the likely times to 1. negotiate a new HTTPS connection 1. read 4MB in a single ranged GET request 1. read less that 4MB in a single ranged GET request, e.g. 2MB. If there's a fixed latency for the GET irrespective of size, then small reads are very inefficient per byte, reading the whole buffer would be justifiable. Also: which makes for the simplest code to write. review and maintain? Let's not ignore that little detail, especially given my experience of shipping a broken implementation of this in S3AInputStream. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
