Review Comment:
> No need to check `_is_load`. Because if this is for load job. the src
tuple descriptor is not null, which has already been checked in `init_block()`
I was thinking, for load job, the `_input_block` has already been
initialized in `VScanner::_init_input_block`. Checking `_is_load` is to avoid
initialize the `_input_block` again.
