> Project: Beam
> Issue Type: Improvement

>
> During execution, the `ReadAllViaFileBasedSource` runs ReShuffle and creates
> an un-grouped set of file range readers. This can easily cause OOM issues
> when the number of groups changes as there is no limit to the number of
> concurrent file reads.
>
> Using Reshuffle.viaRandomKeys.withNumBuckets instead will allow the same
> default behavior, but lets the user configure the number of readers as and
> when needed.
