RuleApplyDataMaskingStage0

case class RuleApplyDataMaskingStage0(spark: SparkSession) extends Rule[LogicalPlan] with RuleHelper with Product with Serializable

The full data masking rule contains two separate stages.

Step1: RuleApplyDataMaskingStage0

  • lookup the full plan for supported scans
  • once found, get masker configuration from external column by column
  • use spark sql parser to generate an unresolved expression for each masker
  • add a projection with new output on the right top of the original scan if the output has changed
  • Add DataMaskingStage0Marker to track the original expression and its masker expression.

Step2: Spark native rules will resolve our newly added maskers

Step3: RuleApplyDataMaskingStage1
