> BlockInputStream: Avoid buffer copy if the whole chunk is being read
> --------------------------------------------------------------------

> Key: HDDS-1529
> URL: https://issues.apache.org/jira/browse/HDDS-1529
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Hanisha Koneru
> Priority: Major
>
> Currently, BlockInputStream reads chunk data from DNs and puts it in a local
> buffer and then copies the data to clients buffer. This is required for
> partial chunk reads where extra chunk data than requested might have to be
> read so that checksum verification can be done. But if the whole chunk is
> being read, we can copy the data directly into client buffer and avoid double
> buffer copies.
