Gary Dusbabek commented on CASSANDRA-1472:
------------------------------------------
bq. We can re-implement a file format identical to the specification...
That's not so different than rolling our own serialization. At that point,
we've gained nothing but interop (how much of a goal is that? If it is, it
needs to be stated) by using avro structures and serialization.

> Bitmap indexes are a very efficient structure for dealing with immutable
> data. We can take advantage of the fact that SSTables are immutable by
> attaching them directly to SSTables as a new component (supported by
> CASSANDRA-1471).
