> Yes, the issue is most DB's (and SQL itself) simply use the timestamp - timestamp = interval pattern. However, from our perspective using durations is fine as long as there is casting/coercing mechanism to take care of the transformation cheaply. I think the core problem is clear distinction between "duration" and "interval" that is made in Arrow and Rust is not found in SQL (e.g. there is no SQL duration type). The coercion / casting logic in DataFusion I think is the right place to reconcile the various Arrow types (Intervals with different time units, durations with different time units) -- This is an automated message from the Apache Git Service.
