Stu Hood commented on CASSANDRA-777:
------------------------------------
Well, we won't need to read from a new format until we merge a new format, but
we wouldn't want to do all of that in one patchset.
I'd like to submit separate issues that:
1. Modify this interface to use it to make the reading half of compactions
memory efficient (almost exactly like the Slice/Scanner API I submitted for 674)
2. Add the new file format (with the next Scanner/Reader subclasses) to make
the writing half of compaction memory efficient.
I'd like to try and submit the first issue tonight (pending fixing one nagging
bug).
