Holds stats for each cached column.
Holds stats for each cached column. The optional
upperBoundandlowerBoundshould be of the same type as the original column. If they are null, then it is assumed that they are not provided, and will not be used for filtering.upperBound(optional)lowerBound(Optional)nullCount:IntrowCount:IntsizeInBytes:Long
These are repeated for each column in the original cached data.
