I'm not sure `a.b` can be pushed down if `a` is a deeply nested array. I'm not against adding a new internal expression to extract field from nested array, if it's needed by `unnest`. I'm -1 to overload `a.b` to support arbitrary levels of nested arrays. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
