> This issue is the next on the road to finally fixing CASSANDRA-16. To make
> compactions memory efficient, we have to be able to perform the compaction
> process on the smallest possible chunks that might intersect and contend
> one-another, meaning that we need a better abstraction for reading from
> SSTables.
