> One of the things that will be needed as the SQL implementation matures is the ability
to do arithmetic operations. For example:
> select (a+b) from x;
> select sum(a)+sum(b) from x;
> We will need to support arithmetic operations within the Streaming API to support these
types of operations.
> It looks like adding arithmetic operations to the SelectStream is the best place to add
this functionality.
