double |
DistinctCostEstimator.getCostOfColumnGroup(CompressedSizeInfoColGroup g) |
double |
ICostEstimate.getCostOfColumnGroup(CompressedSizeInfoColGroup g)
If the instruction does not care about the inter column group cost, such as in memory cost or in computation cost
of right or left matrix multiplication we simply estimate the cost of individual column groups.

abstract CompressedSizeInfoColGroup |
CompressedSizeEstimator.estimateCompressedColGroupSize(int[] colIndexes,
int estimate,
int nrUniqueUpperBound)
A method to extract the Compressed Size Info for a given list of columns, This method further limits the estimated
number of unique values, since in some cases the estimated number of uniques is estimated higher than the number
estimated in sub groups of the given colIndexes.
