> With the new sstable format introduced in CASSANDRA-8099, it's very likely that enabled
sstable compression is no longer the right default option.
> [~slebresne]'s [blog post|http://www.datastax.com/2015/12/storage-engine-30] on the new
storage engine has some comparison numbers for 2.2/3.0, with and without compression that
show that in many cases compression no longer has a significant effect on sstable sizes -
all while sill consuming extra resources for both writes (compression) and reads (decompression).
> We should run a comprehensive set of benchmarks to determine whether or not compression
should be switched to 'off' now in 3.x.
