> I would be very interested in trying to specialize the row_hash grouping operator t avoid the Row format entirely (and use a native Vec<T> for primitive types) and see how that compares with the fixed width row Hi @alamb, there are three reasons that I use the fixed width row: - It covers the null value - It may contain multiple columns not just for one column - For single column case, to embed a variable length column value, like String, to the RawTable may not be good. -- This is an automated message from the Apache Git Service.
