> 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.
