This is a stacked PR. See incremental diff here: https://github.com/AnishMahto/spark/compare/SPARK-59208-introduce-ignore-null-change-arg...SPARK-59183-populate-verison-map-at-ingest See previous PR in stack here: https://github.com/apache/spark/pull/58505 ### What changes were proposed in this pull request? When processing an incoming microbatch, if ignore-null is enabled for the AutoCDC flow, a non-null version map needs to be populated for every row in the microbatch. As per the version map contract (see `Scd2VersionMap`'s scaladoc), the version map is populated with null-authorship information for every event, respecting the currently active ignore-null selection. This ticket is not concerned with reconciling the microbatch's version maps with existing rows in the aux/target table. ### Why are the changes needed? Core part of the algorithm for supporting ignore-null API in SCD2. ### Does this PR introduce _any_ user-facing change? No. The user facing interfaces for ignore-null are not exposed yet, this logic cannot be hit yet. ### How was this patch tested? Unit tests. ### Was this patch authored or co-authored using generative AI tooling? Co-authored with GPT-5.6 Sol. -- This is an automated message from the Apache Git Service.
