Luke Cwik reassigned BEAM-2081:
-------------------------------
Assignee: Luke Cwik
> I/O Authoring overview - better clarify how to read from files
> --------------------------------------------------------------
>
> Key: BEAM-2081
> URL: https://issues.apache.org/jira/browse/BEAM-2081
> Project: Beam
> Issue Type: Improvement
> Components: website
> Reporter: Stephen Sisk
> Assignee: Luke Cwik
> Priority: P3
>
> The I/O authoring doc is a little bit confusing - it has an example of
> reading from file globs and says to use ParDos, but then mentions "A class
> derived from FileBasedSource is often the best option when reading from files"
> It'd be nice to better clarify this and provide guidance as to when to use
> which.
> I *think* the right answer here is that if you file is splittable you use FBS
> (and let it handle the glob splitting), and if it's not splittable you use
> ParDos.
> SDF I believe will make all this easier.
