> KSMetaData/CFMetaData serialization is fragile.  We need to be able to add fields easily
without breaking when we read old-style serialized bytes.
> Avro and Thrift are designed to handle this.  We should probably use one of those rather
than re-inventing the wheel.  If Avro is mature enough for this then let's use that, otherwise
let's use Thrift.
