SZaru: Porting of excellent Sawzall aggregators.Overview Example Install Document Source License Overview SZaru is a library to use Google's Sawzall aggregators in pure C++, Ruby and Python. Sawzall aggregators use memory efficient and one-pass algorithms to approximately compute popular statistics. For example, a simple algorithm of 'top N' computation requires O(K) memories where K means the number of unique elements. But SZaru requires only
