Sylvain Lebresne commented on CASSANDRA-3871:
---------------------------------------------
I believe this only turn compression on for column family initially created
from a thrift structure, as otherwise the default in CFMetaData.init() is still
to not use compression. I believe this has 2 consequences that I can see:
# it doesn't set compression by default for CF created through CQL, since
CreateColumnFamilyStatement uses CFMetaData directly. we should at least fix
that one.
# it doesn't set compression by default for the system CF, nor for secondary
indexes. But for those one, that may be something we want, I don't know. On the
one side, if we think compression is a better default, why not use it for
everything, but on the other side, the user has not way to disable compression
for those, so we may want to wait a little bit more before enabling it there.
