Hello All,

Thank you very much for your answers.

To sum up, here's my understanding of Storm 2.0.0 upcoming features related
to my questions:

* Even if Storm 2.0.0 won't be the same as JStorm, we're going to have at
least:
   - a rewrite of existing Closure source in Java
   - not exactly a Beam Runner, but a streaming API anyway, which
event-time processing features
* Storm 2.0.0 will have Java 9 Run-time support except for Hive & Cassandra
extensions

Is it correct?

Best regards,
Alexandre Vermeerbergen
