DeltaStatsColumnSpec

case class DeltaStatsColumnSpec(deltaStatsColumnNamesOpt: Option[Seq[UnresolvedAttribute]], numIndexedColsOpt: Option[Int]) extends Product with Serializable

Specifies the set of columns to be used for stats collection on a table. The deltaStatsColumnNamesOpt has higher priority than numIndexedColsOpt. Thus, if deltaStatsColumnNamesOpt is not None, StatisticsCollection would only collects file statistics for all columns inside it. Otherwise, numIndexedColsOpt is used.
