> Key: HIVE-6429

> Project: Hive
> Issue Type: Improvement

> The only thing that MJK really needs it hashCode and equals (well, and
> construction), so there's no need to have array of writables in there.
> Assuming all the keys for a table have the same structure, for the common
> case where keys are primitive types, we can store something like a byte array
> combination of keys to reduce the memory usage. Will probably speed up
> compares too.
