I have a column family that contains a large amount of compressed binary data, and I'm interested in disabling the compression as I believe it is wasting CPU cycles.
Two questions:
1) Are CPU cycles really being wasted 'compressing' this already compressed binary data?
2) If so, how do I disable the compression (currently using the SnappyCompressor). I tried all the these without success (ie. describe shows that the SnappyCompressor is still in use):
UPDATE COLUMN FAMILY XXX WITH compression_options={sstable_compression:''};
UPDATE COLUMN FAMILY XXX WITH compression_options={''};
UPDATE COLUMN FAMILY XXX WITH compression_options=null;
An additional bonus question. :) Is there any way to show the current compression ratio for an existing column family?
Thank you,
Daniel
