I have a column family with really wide rows set to use Snappy like this:
compression_options = {'sstable_compression' :
'org.apache.cassandra.io.compress.SnappyCompressor'}
My understanding is that if a file is compressed I should not be able
to use "strings" command to view its contents. B

It starts for new SSTables created after the schema was altered.

Compressed SSTables include a -CompressionInfo.db component on disk.

@OP :
If you want to compress all existing SSTables, use "upgradesstables"
or "cleanup", both of which rewrite existing SSTables 1:1.
