Work Description: reuvenlax opened a new pull request #4989: [BEAM-3979]
Start completing the new DoFn vision: plumb context parameters into process
functions.
URL: https://github.com/apache/beam/pull/4989
This PR starts plumbing remaining parameters directly to function arguments,
eliminating the need for ProcessContext of TimerContext in most places. For
example, a WordCap ParDo might now contain the following:
@ProcessElement
public void process(@Element String word, OutputReceiver receiver) {
receiver.output(word.toUpperCase());
}
The majority of arguments (element, timestamp, pane, output receiver, time
domain) are plumbed in this PR. This PR does not yet add support for
finish-bundle output or for side inputs; both require some design discussion
first, which will happen on the dev list.

> This was intended in the past, but never completed. Ideally all primitive
> parameters in ProcessContext should be injectable, and OutputReceiver
> parameters can be used to collection output. So, we should be able to write a
> DoFn as follows
> @ProcessElement
> public void process(@Element String word, OutputReceiver<String> receiver) {
> receiver.output(word.toUpperCase());
> }
