> The reason for this is many builtin functions like SUM won't work on longs
> (you can workaround using LongSum, but that's lame) because the query planner
> doesn't know about the types beforehand, even though we are casting to native
> longs.
> There is some impact to this, though. With LoadMetadata implemented,
> existing scripts that specify schema will need to remove it (since LM is
> doing it for them) and they will need to conform to LM's terminology (key,
> columns, name, value) within the script. This is trivial to change, however,
> and the increased functionality is worth the switch.
