Yes. I'm thinking about adding a typed serializer interface to Gearpump and
 the default serializer based on Kryo could be type of "Any" in Scala. Then
it's trivial to add support for Coder.

Certainly, it's in our plan. Off the top of my head, Gearpump is built on
Akka Actors and side inputs could be actor states which we can query with
messages. Any good ideas about how a do it in a streaming engine (not
specifically on Gearpump) ?

The code is at
https://github.com/manuzhang/incubator-beam/tree/gearpump_runner. Nothing
is working yet and I still need to fix styles, add docs and tests. The
focus now is to get a working example first.

I also created an umbrella jira (
https://issues.apache.org/jira/browse/GEARPUMP-21) to track status and
related issues at Gearpump side and notify the Gearpump community.

Regards,
Manu
