      To support readAfterOptime, we can return the last visible optime in the repldata metadata. This value should be one of three things:

      • for read commands:
        • if read concern level majority was used for the read, the last visible optime should be the optime of the snapshot last used to return data for the query.
        • if read concern level local was used, the last visible optime should be the last written optime in the oplog at the time of the query's conclusion
      • for write commands:
        • the last visible optime should simply be the optime assigned to the write operation
