Type Members

  1. type DeltaTableScanType = (LogicalPlan, Seq[Expression], FileIndexType, Option[Int], LogicalRelation)

    The components of DeltaTableScanType are: - the plan with removed projections.

    The components of DeltaTableScanType are: - the plan with removed projections. We remove projections as a plan differentiator because it does not affect file listing results. - filter expressions collected by PhysicalOperation - the FileIndexType of the matched DeltaTable - integer value of limit expression, if any - matched DeltaTable

  18. def unapply(plan: LogicalPlan): Option[DeltaTableScanType]

    This is an extractor method (basically, the opposite of a constructor) which takes in an object plan and tries to give back the arguments as a DeltaTableScanType.
