Sylvain Lebresne commented on CASSANDRA-47:
-------------------------------------------

bq. This should be a per-cf option IMO with a default of "compressed"

I'm -1 on the default to compressed. This would mean upon upgrade, people would 
get their file compressed unless they do something about it. This is new code 
and we're talking about the data files. I will be happy to set the default to 
compressed in a year, but not now.

> We should be able to do SSTable compression which would trade CPU for I/O 
> (almost always a good trade).
