-----------------------------------
Summary: AutoCDC SCD2 Invalidated Reserved Framework Cols in
Source/Column Selection
Key: SPARK-57251
URL: https://issues.apache.org/jira/browse/SPARK-57251
Project: Spark
Issue Type: Sub-task
Components: Declarative Pipelines
Affects Versions: 4.3.0
Reporter: Anish Mahto
Reserved framework columns in SCD2 are columns that will be projected onto the
microbatch/target table by the core reconciliation algorithm, and therefore:
* The user's source dataframe should not contain columns with the same name,
because they would get replaced or throw a name conflict error on
reconciliation.
* The user should not be able to exclude these columns through target column
selection via the AutoCDC API
