Alex Bocharov 9963e2f160 Fix uniqHLL12 and uniqCombined for cardinalities 100M+. ... * Changing size() return type from UInt32 to UInt64 to prevent overflow (this shouldn't break back compatibility). * Removing "big cardinalities fix" for cardinalities >2^32/30 as it was very inaccurate and for estimates >2^32 it was trying to do 'log' of negative number which is NaN and it was casted to 0. * Adding python script to show that intHash32 is not a good choice for HyperLogLog algorithm when it's used for linear counting branch of it. * Adding bash script to test uniq, uniqHLL12, uniqCombined on different set cardinalities. * Altering documentation of uniq* aggregate functions with recommendations to use uniq instead of uniqHLL12 or uniqCombined.		2018-01-31 11:36:01 +00:00
