> Loaded data from snapshot then enabled  `sstable_compression: org.apache.cassandra.io.compress.SnappyCompressor`
> Then flush, scrub and compact. I can see actual CompressionRatio in JMX Console and access
my data without problems..
> Now I snapshot compressed keyspace and when trying to load snapshot to another single
node or different Keyspace (the same super CF structure with compression options enabled,
even try to truncate snapshoted CFs.) I cant load any data. 
> sstableloader command with debug mode dont throw any errors and shows its streaming
