> Project: Spark

> Components: Spark Core
> Reporter: Josh Rosen

>
> The current implementation of RDD.take() waits until all partitions of each
> job have been computed before checking whether enough rows have been
> received. If take() were to perform this check on-the-fly as individual
> partitions were completed then it could stop early, offering large speedups
> for certain interactive queries.
