      The TTL monitor only works on index specifications with the expireAfterSeconds option present. Because collections with clustered indexes do not have an _id index entry, the TTL monitor will skip them. The TTL monitor will have to be updated to handle clustered indexes. The TTL monitor only performs deletions on ranged index scans. The TTL monitor should perform deletions using ranged collection scans on collections with clustered indexes.
