> SCD2 Ignore-null support; Populate version map per event row at ingest
> ----------------------------------------------------------------------
>
> Key: SPARK-59183
> URL: https://issues.apache.org/jira/browse/SPARK-59183
> Project: Spark
> Issue Type: Sub-task
> Components: Declarative Pipelines
> Affects Versions: 4.4.0
> Reporter: Anish Mahto
> Priority: Major
> Labels: pull-request-available
>
> 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.
