-----------------------------------------
Summary: 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: Herman van Hovell
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.
