    Description

      For resumable index builds, in order to ensure that we do not need to roll back any of the keys inserted into the sorter, the collection scan should start at a timestamp that has been majority committed. We will also need to ensure that the side writes table doesn't miss any writes. When we initially begin the collection scan, we must first install the side writes interceptor and then wait for the last oplog entry (the last entry that was not captured by the interceptor) to become majority committed, before establishing the snapshot to read the collection.
