Marek Vavruša 5f1e65b252 AggregateFunctions: implemented topK(n) ... This implements a new function for approximate computation of the most frequent entries using Filtered Space Saving with a merge step adapted from Parallel Space Saving paper. It works better for cases where GROUP BY x is impractical due to high cardinality of x, such as top IP addresses or top search queries.		2017-05-03 23:09:52 -07:00
