Was chatting with @roshannaik and @dan-blanchard today, and this PR came up.
Someone on Storm team may benefit from taking a look at this as part of the
performance revisions being done for Storm 2.0. As mentioned in [#428 in
streamparse](https://github.com/Parsely/streamparse/issues/428#issuecomment-380135343)
-- the community project for running Python multi-lang topologies with Storm
-- getting this merged somewhere in the Storm codebase would open up the
possibility to switch serializer from Kryo & JSON to msgpack throughout, which
would speed up multi-lang use cases considerably. This PR includes a pure Java
implementation of a msgpack serializer, as well as pointers to the right
msgpack library in the Java community; it just needs to be reviewed, tested,
and merged.
