CompressedSizeInfoColGroup |
CompressedSizeEstimator.estimateCompressedColGroupSize()
Method used for compressing into one type of colGroup
|
CompressedSizeInfoColGroup |
CompressedSizeEstimator.estimateCompressedColGroupSize(int[] colIndexes)
Method for extracting Compressed Size Info of specified columns, together in a single ColGroup
|
abstract CompressedSizeInfoColGroup |
CompressedSizeEstimator.estimateCompressedColGroupSize(int[] colIndexes,
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.
