This seems reasonable to me :metal:. How does `ResultRow` work in practice? Do the dimensions/virtual-columns/aggs/post-aggs of a `GroupByQuery` I guess form a schema of sorts that can map the columns to a position in a stable manner between brokers and historicals? If I don’t elect to translate the array results to a map row at the broker level, does it include a ‘header’ row of sorts that captures that schema?
