> Key: SPARK-60274
> URL: https://issues.apache.org/jira/browse/SPARK-60274
> Project: Spark
> Issue Type: Sub-task
> Components: Declarative Pipelines
> Affects Versions: 4.4.0
> Reporter: Anish Mahto
> Priority: Major
>
> Add the complete microbatch reconciliation entry point for SCD1 ignore-null,
> which wires together the existing leaf-level implementation has individual
> stages for target-schema alignment, version-map population, within-batch
> coalescing, and persisted-tombstone reconciliation.
> Leaf-level reconciliation requires the target schema, unlike row-level
> reconciliation. Therefore also get rid of the `Scd1ReconciliationStrategy`
> trait and its abstract `reconcileMicrobatch` interface, in favor of two
> independent reconciliation strategy objects that share some common helper
> methods.
