Benedict commented on CASSANDRA-7978:
-------------------------------------

We only need to set the value wherever it's retrieved from, and call 
FileCacheService.invalidate() on each of the files we've changed the setting 
for.

I'd kind of prefer, if we want to make this setting configurable live, to drop 
maintenance of the setting from compression metadata and just fetch it from the 
CFMetaData each time we open a reader.

> 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.
