TTL indexes reposition the cursor often to continue deleting the obsolete records. The repositioning uses a search_near which is biased to walk in one direction looking for the records than the other. This could cause a performance issue if the cursor has to walk through a lot of deleted records. The bounded cursor offers a means to limit the range the search_near has to walk, potentially improving the performance.
