We generalize cursor traits to iterate and search in both directions.
This is a step toward introducing support for SQL operators that manipulate ordered groups of rows, including
ORDER BY ASC/DESC,RANK,ROW_NUMBER,top-k, etc. These operators require the ability to enumerate rows in both ascending and descending orders. Our cursors did not support that as they only allowed iterating and seeking forward.This commit extends cursor traits with methods to iterate and seek backward. A cursor is always created pointing to the first record. In order to iterate backward, the client must first move the cursor to the end of the range using the new
fast_forward()method.For batch and trace cursors we allow reverse iteration by both keys and values.
So far the new infrastructure is only used to implement the
Maxaggregate more efficiently. Upcoming commits will make a more extensive use of it.
