[SPARK-24251][SQL] Add AppendData logical plan. ## What changes were proposed in this pull request? This adds a new logical plan, AppendData, that was proposed in SPARK-23521: Standardize SQL logical plans. * DataFrameWriter uses the new AppendData plan for DataSourceV2 appends * AppendData is resolved if its output columns match the incoming data frame * A new analyzer rule, ResolveOutputColumns, validates data before it is appended. This rule will add safe casts, rename columns, and checks nullability ## How was this patch tested? Existing tests for v2 appends. Will add AppendData tests to validate logical plan analysis.

This adds a new logical plan, AppendData, that was proposed in SPARK-23521. This also adds an analyzer rule to validate data written with AppendData against the target table. DataFrameWriter is also updated so that v2 writes use the new AppendData logical plan. ---- --- --------------------------------------------------------------------- To unsubscribe, e-mail: reviews-unsubscr...@spark.apache.org For additional commands, e-mail: reviews-h...@spark.apache.org
