    Description

      The new replication in 2.2 updates minvalid much more often, and it stores the entire op document. These documents can be rather large, and may leave behind empty extents.

      This improvement would be to only store the timestamp and the hash as minvalid, and leave off the document data field. This will be faster and the doc size will stay the same so it doesn't need to move around in the extent as it gets updated.
