Subject [jira] [Commented] (BEAM-638) Add sink transform to write bounded data per window, pane, [and key] even when PCollection is unbounded
Date Sun, 07 May 2017 15:32:04 GMT

Davor Bonaci commented on BEAM-638:
-----------------------------------

I believe this JIRA is fixed, as we have windowed file writes now. Resolving.

(Feel free to continue the discussion here, or on the mailing list, or in a separate issue.)

> Today, if the pipeline source is unbounded, and the sink expects a bounded collection,
there's no way to use a single pipeline. Even a window creates a chunk on the unbounded PCollection,
but the "sub" PCollection is still unbounded.
> It would be helpful for users to have a Window function that create a bounded PCollection
(on the window) from an unbounded PCollection coming from the source.
