> ------------------------------------------------------------

> Key: SPARK-28863
> URL: https://issues.apache.org/jira/browse/SPARK-28863
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Burak Yavuz
> Priority: Major
>
> With the DataSourceV2 write operations, we have a way to fallback to the V1 writer APIs using InsertableRelation.
> The gross part is that we're in physical land, but the InsertableRelation takes a logical plan, so we have to pass the logical plans to these physical nodes, and then potentially go through re-planning.
> A useful primitive could be specifying that a plan is ready for execution through a logical node AlreadyPlanned. This would wrap a physical plan, and then we can go straight to execution.
