 ## This extension currently supports the following sketches:
 
 - CPC (Compressed Probabilistic Counting) sketch - very compact (smaller than HLL when serialized) distinct-counting sketch
-- Theta sketch - distinct counting with set operations (union, intersection, a-not-b)
 - HLL sketch - very compact distinct-counting sketch based on HyperLogLog algorithm
-- KLL float quantiles sketch - for estimating distributions: quantile, rank, PMF (histogram), CDF
+- Theta sketch - distinct counting with set operations (union, intersection, a-not-b)
+- Array Of Doubles (AOD) sketch - a kind of Tuple sketch with array of double values associated with each key
+- KLL (float and double) quantiles sketch - for estimating distributions: quantile, rank, PMF (histogram), CDF
+- Quantiles sketch (inferior to KLL, for long-term support of data sets)
 - Frequent strings sketch - capture the heaviest items (strings) by count or by some other weight
