This is + * needed because {@code DICT}'s {@code keys} field is not projected but is needed + * to be initialized to ensure the dict vector is constructed properly. Review comment: Dict works the same as arrays regarding projection: if the user refers to any `DICT` entry, the whole `DICT` is projected and finding the needed entry is to be handled by some other operator. This entry is not filtered in the Scan. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
