Weihua Jiang commented on GEARPUMP-23:
--------------------------------------

Hi Fabio,

Thanks  a lot for your comment. 

Gearpump plans support multiple DSLs. Currently there are Gearpump native DSL, 
Akka Streams and Apache Beam on the list. As the current support for Apache 
Beam is translating to Gearpump native DSL, we will need some feature 
enhancements in Gearpump native DSL.

Hope this clarify things.
