Sylvain Lebresne updated CASSANDRA-5664:
----------------------------------------
Attachment: 0002-Avoid-copy-when-compressing-native-protocol-frames.txt
0001-Rewrite-encoding-methods.txt
Attaching patch for this. This does clean up serialization a bit, will probably
be a bit faster and allocate less objects. Last but not least, this make it
easy to not do another copy when we compress the frames, which is what the 2nd
patch does.

> Message serialization in the native protocol currently make a Netty's
> ChannelBuffers.wrappedBuffer(). The rational was to avoid copying of the
> values bytes when such value are biggish. This has a cost however, especially
> with lots of small values, and as suggested in CASSANDRA-5422, this might
> well be a more common scenario for Cassandra, so let's consider directly
> serializing in a newly allocated buffer.
