CatalogStatistics

case class CatalogStatistics(sizeInBytes: BigInt, rowCount: Option[BigInt] = None, colStats: Map[String, CatalogColumnStat] = Map.empty) extends Product with Serializable

This class of statistics is used in CatalogTable to interact with metastore. We define this new class instead of directly using Statistics here because there are no concepts of attributes in catalog.
