Jonathan Ellis commented on CASSANDRA-6201:
-------------------------------------------
Approach looks good, but you should reference the sstable (and skip it if
reference failse) before checking the metadata since otherwise you could
include the size of a just-freed segment.
> Expose compression metadata in cfstats
