Vijay updated CASSANDRA-2167:
-----------------------------
Attachment: 0003-Reduce-BB-Copy.txt
0001-Reduce-Byte-Copy-Streams.txt
0002-Reduce-Byte-Copy-BBUtil.txt
0001-Reduce-Byte-Copy-Streams - Introduce New memory Input and Output stream
which will insert the bytes directly into the Native memory and read from it to
avoid copies of data.
0002-Reduce-Byte-Copy-BBUtil - Remove the Old bytebuffer Input and Output
streams
0003-Reduce-BB-Copy - update the SerializedCache to use the new MIS and MOS
> Add a deserialize(ByteBuffer) method to ColumnFamilySerializer

> by adding deserialize bytebuffer in the columnFamilySerializer we might be
> able to avoid copying of the bytes[] while deserializing the CF.
> This can be done using....
> ByteBuffer buff = ByteBuffer.wrap(bb.array(), bb.position(), length);
> This is an improvement on
> "https://issues.apache.org/jira/browse/CASSANDRA-1969"; Plz see jonathan's
> comment.
