      SERVER-56274 (TTL deletes are much slower on descending indexes than ascending indexes) was unknown until a user reported it. We address SERVER-56274 in SERVER-65528 by utilizing bounded cursors. It would be nice to add coverage to detect any future regressions as well as confirm the performance improvements of SERVER-65528 to ensure that TTL deletes now perform similarly on descending indexes as ascending indexes.

      This can be done either with google benchmarks or a genny workload. If using benchmarks, it would be useful to have one for ascending ttl indexes and descending ttl indexes to compare the performance of both.
