    Description

      Add the capability to schedule TTL index deletion, analogous to how we can schedule the cluster balancer.

      Use case: 9-5 systems that want to perform TTL deletion of old data outside of business hours to avoid additional performance overhead during busy periods.

      This can be approximated today by running a cron job to do something like the following, but it would be a nice-to-have in the database:

      • At start of TTL deletion window:

      db.runCommand({collMod: "collection-name",
      		 
                     index: {keyPattern: {ts:1},
      		 
                             expireAfterSeconds: <desired expiry age>}})

      • At end of TTL deletion window:

      db.runCommand({collMod: "collection-name",
      		 
                     index: {keyPattern: {ts:1},
      		 
                             expireAfterSeconds: <some very large value>}})
