----------------------------------------
Github user yukselakinci commented on the issue:
https://github.com/apache/giraph/pull/65
UnsafeByteArray streams now extends kryo Output/Input streams so that kryo
serialization can directly write to this stream without using an additional
buffer, providing a faster serialization.
Tests performed:
- Giraph unit tests
- Snapshot tests
- Run several workloads with different applications and measured
correctness/performance, running time stayed in the boundary of the current
values.

> URL: https://issues.apache.org/jira/browse/GIRAPH-1181
> Project: Giraph
> Issue Type: Improvement
> Reporter: Yuksel Akinci
> Priority: Major
>
> Adding a new stream type which extends from
> com.esotericsoftware.kryo.io.Input/Output, so that it can be used with kryo
> serializer. It improves the performance of kryo by faster read/writes (unsafe
> IO), and also eliminates the need for interim buffers to convert from
> DataInput and DataOutput.
