• Investigate and come up with proposals on how to do our Oplog replication plan for our cloning.
  We have two operations that are othrogonal to each other
• Clone data
• Clone index data

So we need to come up with a plan for :

• Do you need to have a new oplog type, or we can use one of the existent ones ?
• How the primary will batch these writes (data and index) ?
• How the secondary will do on receiving oplog ?
