> 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.
