I think I found a way to keep count of cardinality since a specific time using Flajolet approach! (answering cardinality since timestamp x)

I was thinking more in terms of 64 bit registers with amplification of values based on timestamp! I will check out HLL Series though!
-
there is also https://hal.archives-ouvertes.fr/hal-00465313/file/sliding_HyperLogLog.pdf … which I implemented already but not so happy with it!
-
well, any improvements you find we'd be very interested in.
-
No improvements sadly! So I am implementing what you suggested in Go! seems like a good way of doing it too :D
