FastByteArray*Stream implementations to replace syncronized JDK ByteArray*Stream
--------------------------------------------------------------------------------
Key: IO-286
URL: https://issues.apache.org/jira/browse/IO-286
Project: Commons IO
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.
