> Explicit cast support currently is not available. Explicit cast would be
> useful, since 1) once optiq pass the cast function into logical/physical
> plan, drill execution engine need to parse the cast function in the
> expression and do the casting work, 2) implicit cast would internally build
> an explicit cast function call, to do the casting work.
