Subject TWCS target number of time windows
Date Wed, 21 Aug 2019 11:18:05 GMT
Hi,

In the TWCS readme[1] it says:


You should target fewer than 50 buckets per table based on your TTL.


What is this recommendation based upon?  The docs from Datastax[2], for
example do not mention anything like that.

Is the recommendation still actual today for the version 3.0.$latest?  What
is the computation complexity behind it: is it N, N*log(N) or N^2, etc.?

Thank you.
