Gary Dusbabek commented on CASSANDRA-1472:
------------------------------------------
In the context of CASSANDRA-1015, I think using avro is not the right choice.
For interoperability between nodes, we will need to have the ability to
interpret the bytes as they are being serialized/deserialized. Switching over
to avro/thrift/msgpack removes that choice.
I haven't reviewed the patches on this ticket, but I think we should avoid
handing off serialization with respect to our on-disk storage. Once they
become binary structures, the construction of which we don't care about because
a library is doing it for us, is the moment we lose control of a very
fundamental thing--knowing exactly what we're reading and writing.

> 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).
