---------------------------------
Issue Type: Bug (was: Task)
> sample() imposes partitioning by index unnecessarily
> ----------------------------------------------------
>
> Key: BEAM-13133
> URL: https://issues.apache.org/jira/browse/BEAM-13133
> Project: Beam
> Issue Type: Bug
> Components: dsl-dataframe
> Reporter: Brian Hulette
> Assignee: Brian Hulette
> Priority: P2
>
> I noticed that sample() requires data to repartitioned when it's used at the
> beginning of a series of dataframe commands. In practice we should be able to
> sample within arbitrary partitions before combining the partitions to produce
> the final result.
> It looks like the root cause is that our sample expressions require
> partitioning by index, rather than arbitrary partitioning.
