> As suggested on CASSANDRA-3105, as long as 1.0 is not out, we could replace the 'compression' and 'compression_options' parameters by just one that would allow to write:
> {noformat}
>   compression_options = { sstable_compression: SnappyCompressor, block_length_kb: 32 }
> {noformat}
> This would allow for more future-proof, in particular if we decide to make CASSANDRA-3015 pluggable in the future or for CASSANDRA-3127 as this would allow us to simply evolve to say:
> {noformat}
>   compression_options = { sstable_compression: SnappyCompressor, block_length_kb: 32, stream_compression: LZFCompressor }
> {noformat}
> This has the advantages of (1) not polluting CfDef and (2) leaving the option of documenting some option only in advanced documentation (if said option is not meant for new users)
