Agreed about deflate. Also you can adjust your chunk size, which may help ratios as well, especially if you expect your data to compress well - often larger chunks will compress better, but it depends on the nature of your data.
In the near future, look for work from Sushma @ Instagram to make available ZStandard ( https://jira.apache.org/jira/browse/CASSANDRA-14482 ).
