Davor Bonaci commented on BEAM-265:
-----------------------------------
There are many things conflated here ;)
Are you referring to data-dependent pipeline structure? If so, we fully agree.
This is on the wider roadmap, but not being worked on currently.
In terms of language-independence, Runner API and Fn API work currently in
progress achieves that goal. (There's never full language-independence --
user-defined functions are always language-specific.)
Do you agree, or am I missing something?

> There should conditional / dynamic changes to pipelines and DAGs. The Beam
> specification should ideally be:
> - fully language neutral to support many languages
> - should be specified statically so code generation can work. E.g. pipeline
> specified in Java but run as native. In this case the conversion would be
> like that GWT does with Java.
> In addition the transformation code though expressed in a given language
> should be transformable into an language independent form.
