    Description

      Investigate making initial sync more tolerant regarding network connectivity issues on the sync, i.e. investigate the possibility of a fresh TCP connection to resume the sync as opposed to going back to the start.

      There are three distinct areas that would have to handle this better: the one they ran into (querying the primary for its latest optime), cloning, and connecting to fetch missing documents (as in their linked ticket).

      One could also argue that it should be more flexible about changing initial sync targets mid-stream, however, that may be more difficult.
