Marcus Eriksson commented on CASSANDRA-11550:
---------------------------------------------

This is a duplicate of CASSANDRA-7871 - but I wasn't convinced back then, do you have any
real-life results of reducing the fanout?

> Currently, the fanout size for LeveledCompactionStrategy is hard coded in the system
(10). It would be useful to make the fanout size to be tunable, so that we can change it according
to different use cases.
> Further more, we can change the size dynamically.
