Stu Hood commented on CASSANDRA-1717:
-------------------------------------

Sorry, that was supposed to say #674. We've been dealing with compaction and 
garbage collection issues, and I haven't had as much time to work on it 
recently. I'm hoping to be able to resume #674 in the next few weeks, but I 
don't think it will be 0.8 material.

> Most corruptions of on-disk data due to bitrot render the column (or row) 
> unreadable, so the data can be replaced by read repair or anti-entropy.  But 
> if the corruption keeps column data readable we do not detect it, and if it 
> corrupts to a higher timestamp value can even resist being overwritten by 
> newer values.
