Reynold Xin commented on SPARK-9999:
------------------------------------
This needs to be designed first. I'm not sure if static code analysis is a
great idea since they fail often. I'm open to ideas though.
> RDD-like API on top of Catalyst/DataFrame
> -----------------------------------------
>
> Key: SPARK-9999
> URL: https://issues.apache.org/jira/browse/SPARK-9999
> Project: Spark
> Issue Type: Story
> Components: SQL
> Reporter: Reynold Xin
>
> The RDD API is very flexible, and as a result harder to optimize its
> execution in some cases. The DataFrame API, on the other hand, is much easier
> to optimize, but lacks some of the nice perks of the RDD API (e.g. harder to
> use UDFs, lack of strong types in Scala/Java).
> As a Spark user, I want an API that sits somewhere in the middle of the
> spectrum so I can write most of my applications with that API, and yet it can
> be optimized well by Spark to achieve performance and stability.
