> Key: SPARK-59358
> URL: https://issues.apache.org/jira/browse/SPARK-59358
> Project: Spark
> Issue Type: Sub-task
> Components: Declarative Pipelines
> Affects Versions: 4.4.0
> Reporter: Anish Mahto
> Priority: Major
> Labels: pull-request-available
>
> Once the version map is constructed per incoming row in the microbatch, we
> need to start actually reconciling columns in the incoming microbatch that
> have been deduced as unauthored - they should instead inherit the last known
> authored value.
> While reconciling the affected existing rows from the aux/target table, it's
> also possible out of order received events in the current microbatch affect
> what authored value existing ignored-null columns inherit; these need to be
> updated too.
