• Modified Python generation of msgpack-idl to use in Jubatus

• Added Erlang generation of msgpack-idl

• A small patch sent to msgpack-rpc-python to use in Jubatus

• MessagePack (Erlang) (2010-)

• Yatce: yet another TokyoCabinet-Erlang binding (2009)

• Erlang’s built-in key/value storage system (dets) is very slow and its performance is bad. While TokyoCabinet is a blazingly-fast key/value storage system written in state-of-art C, Yatce connects it with Erlang. It is built into some proprietary software and being sold (Yatce itself is dual-licensed as LGPL/MIT).
