-----------------------------------------
The last post is some time ago. What is the current status of messagepack
implementation in cassandra? I think it would be very nice.

> Key: CASSANDRA-1735
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1735
> Project: Cassandra
> Issue Type: New Feature
> Components: API
> Affects Versions: 0.7 beta 3
> Environment: Fedora11, JDK1.6.0_20
> Reporter: Muga Nishizawa

> For improving Cassandra performance, I implemented a Cassandra RPC part with
> MessagePack. The implementation details are attached as a patch. The patch
> works on Cassandra 0.7.0-beta3. Please check it.
> MessagePack is one of object serialization libraries for cross-languages like
> Thrift and Protocol Buffers but it is much faster, small, and easy to
> implement. MessagePack allows reducing serialization cost and data size in
> network and disk.
> MessagePack websites are
> * website: http://msgpack.org/
> This website compares MessagePack, Thrift and JSON.

> Performance of the data serialization library is one of the most important
> issues for developing a distributed database in Java. If the performance is
> bad, it significantly reduces the overall database performance. Java's GC
> also runs many times. Cassandra has this problem as well.
> For reducing data size in network between a client and Cassandra, I
> prototyped the implementation of a Cassandra RPC part with MessagePack and
> MessagePack-RPC. The implementation is very simple. MessagePack-RPC can
> reuse the existing Thrift based CassandraServer
> (org.apache.cassandra.thrift.CassandraServer)
> while adapting MessagePack's communication protocol and data serialization.
> Major features of MessagePack-RPC are
> * Asynchronous RPC
> * Parallel Pipelining
> * Connection pooling
> * Delayed return
> * Event-driven I/O
> * more details: http://redmine.msgpack.org/projects/msgpack/wiki/RPCDesign
> * source code: https://github.com/msgpack/msgpack-rpc/
> The attached patch includes a ring cache program for MessagePack and its test
> program.
> You can check the behavior of the Cassandra RPC with MessagePack.
> Thanks in advance,
