> For the Messages use case, ~90% of the disk util is associated with major compacted files but less than 33% of the get IOPS are due to mc files.  Allowing a different compaction algorithm for major compacted files will allow us to get ~30% disk savings.  Latency should be higher, but storefile querying is sequential, so only 1/3 of the get latency is from disk access to these files.
