paul-rogers commented on issue #1870: DRILL-7359: Add support for DICT type in
RowSet Framework
URL: https://github.com/apache/drill/pull/1870#issuecomment-561448583
On `ProjectionType`, if the `SchemaPath` is, say, `foo`, then the
`ProjectionType` will be `SCALAR`. I can see that this name is misleading.
Perhaps `SIMPLE` is better. We don't know that the column **is** scalar, we
just know that it is consistent with a scalar. It could be a map, array or dict
as well.
But, if you do add a `SchemaPath` representation for `foo['bar']`, then,
yes, that can only be a `DICT`, so we can introduce a `DICT` projection type.
