Subject [jira] [Commented] (BEAM-265) Dynamic Pipeline, Transformation, etc. / DAG Changes DSL | Full Specification Language Independence, Transo
Date Mon, 09 May 2016 07:48:12 GMT

Suminda Dharmasena commented on BEAM-265:
-----------------------------------------

I am not saying not to support language dependent function but have a mechanism to specify
function in a language independent way.

> 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.
