    When a MERGE operation is rewritten, the target table is joined with the source and each MATCHED/NOT MATCHED/NOT MATCHED BY SOURCE clause is converted into a corresponding instruction on top of the joined plan.

    When a MERGE operation is rewritten, the target table is joined with the source and each MATCHED/NOT MATCHED/NOT MATCHED BY SOURCE clause is converted into a corresponding instruction on top of the joined plan. The purpose of an instruction is to derive an output row based on a joined row.

    Instructions are valid expressions so that they will be properly transformed by the analyzer and optimizer.

  3. case class Keep(condition: Expression, output: Seq[Expression]) extends Expression with Instruction with Product with Serializable
  4. case class Split(condition: Expression, output: Seq[Expression], otherOutput: Seq[Expression]) extends Expression with Instruction with Product with Serializable
