Apache Spark reassigned SPARK-23223:
------------------------------------
Assignee: Apache Spark (was: Herman van Hovell)
> Stacking dataset transforms performs poorly
> -------------------------------------------
>
> Key: SPARK-23223
> URL: https://issues.apache.org/jira/browse/SPARK-23223
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Herman van Hovell
> Assignee: Apache Spark
> Priority: Major
>
> It is a common pattern to apply multiple transforms to a {{Dataset}} (using
> {{Dataset.withColumn}} for example. This is currently quite expensive because
> we run {{CheckAnalysis}} on the full plan and create an encoder for each
> intermediate {{Dataset}}.
> {{CheckAnalysis}} only needs to be run for the newly added plan components,
> and not for the full plan. The addition of the {{AnalysisBarrier}} created
> this issue.
