I'm trying to understand where we'd be after this patch. What algorithm will be used in each of the following cases? - string dimension, no dictionary <-- i.e., what we get from an expression that isn't backed by a single dictionary-coded string column - string dimension, dictionary coded, unique (1-1 mapping from keys -> values) <-- i.e., what we get from a regular column in a segment, or a dictionary-coded string column plus an ExtractionFn that is `ONE_TO_ONE` - string dimension, dictionary coded, nonunique <-- i.e., what we get from an expression backed by a single dictionary-coded string column, or a dictionary-coded string column plus an ExtractionFn that is `MANY_TO_ONE` -- This is an automated message from the Apache Git Service.
