>          Issue Type: New Feature
>          Components: Streams/Writers
>            Reporter: Paul Loy
>            Priority: Minor

> In CASSANDRA-2820 I reintoduced the FastByteArrayInputStream and FastByteArrayOutputStream
to cassandra. These steams are un-synchronized versions of the Apache Harmony ByteArrayInputStream
and ByteArrayOutputStream respectively.
> During my own testing of the streams I found a big difference in the performance of the
standard JDK BA*S steams and the FBA*S streams on most JREs. Then cassandra load testing also
showed an up to 10% improvement in cassandra performance using these streams.
> Then Thrift has TByteArrayOutputStream which contains a way to get the underlying byte[]
buffer without a deep copy that would probably be a good further enhancement.
> Patch to follow.
