>             Project: Beam
>          Issue Type: New Feature

> This is a general feature request based on frequent questions I see on Stack Overflow. I often see questions about how to get an empty file instead of no file when a PCollection is empty, or vice versa for IOs that create empty files. In other words, whichever approach is taken, there's users that will want the opposite approach.
> It seems the best approach here would be to add some kind of common code (FileIO maybe?) that could either open files for writing in Setup or lazily in ProcessElements.
> Regardless of the approach taken, this bug is basically for investigating this feature for feasibility and maybe holding sub-tasks/blocking bugs for tracking implementation.
