Investigate changes in SERVER-45468: Create a DBClientCursor in the new oplog fetcher

XMLWordPrintableJSON

      Description

      Downstream Change Summary

      Added a new server parameter called oplogFetcherUsesExhaust which can be set at startup. It will set whether oplog fetching will use exhaust cursors or not.

      This ticket should also cover what this means; i.e. streaming replication vs oplog batches.

      Description of Linked Ticket

      As a part of this ticket, we should investigate whether we can set the socket timeout on the connection before the cursor is initialized (and the find command is run) and after the cursor is initialized. If possible, this would allow us to set a timeout for when the find is running and a separate getMore timeout.

      We should also implement logic to create a new cursor when an error is encountered.
