> Key: SPARK-14202
> URL: https://issues.apache.org/jira/browse/SPARK-14202
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 1.3.0, 1.4.0, 1.5.0, 1.6.0, 2.0.0
> Reporter: Maciej Szymkiewicz
>
> At this moment {{python_full_outer_join}} is the only join operation on
> Python RDDs which uses list comprehension instead of generator expression in
> its {{dispatch}} function.
> It doesn't look like there is any particular reason that could justify this
> choice and it can lead to serious performance issues.
