DoubleCardinalityAggregatorColumnSelectorStrategy	If performance of this class appears to be a bottleneck for somebody, one simple way to improve it is to split it into two different classes, one that is used when NullHandling.replaceWithDefault() is false, and one - when it's true, moving this computation out of the tight loop
FloatCardinalityAggregatorColumnSelectorStrategy	If performance of this class appears to be a bottleneck for somebody, one simple way to improve it is to split it into two different classes, one that is used when NullHandling.replaceWithDefault() is false, and one - when it's true, moving this computation out of the tight loop
LongCardinalityAggregatorColumnSelectorStrategy	If performance of this class appears to be a bottleneck for somebody, one simple way to improve it is to split it into two different classes, one that is used when NullHandling.replaceWithDefault() is false, and one - when it's true, moving this computation out of the tight loop
