Labels: pull-request-available (was: )
> Support native CDC changelog sources as input to AutoCDC flows
> --------------------------------------------------------------
>
> Key: SPARK-57331
> URL: https://issues.apache.org/jira/browse/SPARK-57331
> Project: Spark
> Issue Type: Improvement
> Components: Declarative Pipelines
> Affects Versions: 5.0.0
> Reporter: Szehon Ho
> Priority: Major
> Labels: pull-request-available
>
> Allow AutoCDC (SCD Type 1) flows in Spark Declarative Pipelines to consume
> Spark native CDC (Changelog) sources directly. When a flow source is detected
> as a native Changelog read, AutoCDC auto-derives its CDC semantics (delete
> detection, metadata-column exclusion, and update_preimage filtering) from the
> changelog contract instead of requiring the user to hand-map them. Includes
> validation that the changelog read is configured for unambiguous,
> deterministic reconciliation (computeUpdates for delete+insert updates,
> carry-over removal, and _commit_version sequencing). Scala-first scope;
> Python/Connect APIs deferred.
