T Jake Luciani commented on CASSANDRA-7978:
-------------------------------------------

bq.  I think we'd want to be able to change the value live and have it 
immediately reflected.

This isn't the kind of setting you want to constantly tune live so I'm not sure 
we want to get too fancy with it (rolling restart seem reasonable) and keep in 
mind things would improve over time due to compaction.  

If you feel strongly we could add code to reopen all the readers when this 
setting is changed.

> CrcCheckChance should not be stored as part of an sstable

> CrcCheckChance is stored with compression parameters in the sstable. The only 
> way to change it is to do upgrade sstable. I don't see why it should not be a 
> hot property.
