[jira] [Assigned] (SPARK-36263) Add Dataset.observe(Observation,
Column, Column*) to PySpark

> Add Dataset.observe(Observation, Column, Column*) to PySpark
> ------------------------------------------------------------
>
> Key: SPARK-36263
> URL: https://issues.apache.org/jira/browse/SPARK-36263
> Project: Spark
> Issue Type: New Feature
> Components: PySpark
> Affects Versions: 3.3.0
> Reporter: Enrico Minack
> Priority: Major
>
> With SPARK-34806 we now have a way to use the `Dataset.observe` method without the need to interact with `org.apache.spark.sql.util.QueryExecutionListener`. This allows us to retrieve observations in PySpark, which does not support listener callbacks.
> Adding a `Dataset.observe(Observation, Column, Column*)` equivalent to PySpark's `DataFrame` is straightforward while it allows to utilise observations from Python.
