----------------------------------

(was: Linking - If compaction uses a priorityqueue, we should consider both the issue in 11218 (prioritize certain types of compaction over others) and 6288 (prioritize typical compaction based on CF characteristics).)

> We should prioritize compacting CFs by how many reads/s its preferred candidate would save, divided by the number of bytes in the sstables.
> (Note that STCS currently divides by number of keys; ISTM that bytes will work better since that does not penalize narrow rows.)
