Hello users

On the official documentation for TWCS (
http://cassandra.apache.org/doc/latest/operating/compaction.html#time-window-compactionstrategy)
it is advised to select the windows unit and size so that the total number
of windows intervals is around 20-30.

Is there any explanation for this range of 20-30 ? What if we exceed this
range, let's say having 1 day windows and keeping data for 1year, thus
having indeed 356 intervals ? What can go wrong with this ?

Regards

Duy Hai DOAN
