---------------------------------------
Summary: Build SCD2 AutoCDC auxiliary table spec and
materialization
Key: SPARK-58320
URL: https://issues.apache.org/jira/browse/SPARK-58320
Project: Spark
Issue Type: Sub-task
Components: Declarative Pipelines
Affects Versions: 5.0.0
Reporter: Andreas Neumann
Implement buildScd2AuxiliaryTableSpecFor in AutoCdcAuxiliaryTable.scala
(currently throws an internal error: 'SCD2 auxiliary table derivation is not
yet implemented'). The SCD2 auxiliary table shape is keys + _cdc_metadata + the
aux-only __spark_autocdc_deleted_by_batch_id column, which is richer than the
SCD1 aux table. Confirm DatasetManager materializes and schema-evolves the SCD2
aux table correctly. Dormant until the switch-flip subtask, since no SCD2 flow
can resolve before then. Sub-task of the SCD2 end-to-end enablement effort
under SPARK-56249.
