> Buffer Pool in BlockInputStream
> -------------------------------
>
> Key: HDDS-1528
> URL: https://issues.apache.org/jira/browse/HDDS-1528
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Hanisha Koneru
> Priority: Major
>
> In BlockInputStream, when a new chunk is being read, the data in old buffers
> is thrown away. So, if we want to read data in chunk1 and then chunk2 and
> then go back to reading chunk1, we would have to fetch chunk1 again from the
> DNs.
> Reads can be optimized if we maintain a buffer pool instead instead of only
> one buffer. This way, we can cache chunk data for re-reads.
