Jonathan Ellis commented on CASSANDRA-446:
------------------------------------------
Note that while using DK objects means we could easily serialize the
BigIntegers (in particular) more efficiently than as Strings I'd like to avoid
messing with the on-disk format for 0.5 if we can at all help it.
> Use DecoratedKey objects in Memtable, SSTableReader/Writer objects

> See CASSANDRA-420 for introduction of DecoratedKey.
> IMO we should move Memtable and SSTR objects to using DK objects, too. This
> will help Memtable flushes similar to how this helps BMt, and using DK
> objects in SSTR will avoid a ton of potential confusion about whether a
> String is a key or a decorated key.
> As a side benefit, moving the decoration operation out of memtable flush and
> into the insert path will help make better use of multicore systems, since we
> can have multiple write threads but only one core can flush at a time. (See
> CASSANDRA-445.)
