    Description

      Hello,

      On WT-4090 the WiredTiger team implemented a read_once cursor option. This is useful when we know that we are going to read the data only once, helping to avoid populating the cache with data we don't need.

      This has been proved beneficial to reduce the index creation time (SERVER-37269), and I think that would be very useful when used by the collection clone process during the initial sync too.

      Regards,
      Miguel
