> 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.
