    Description

      The 3.6 server will support two rollback implementations

      • A new implementation that is reliant on 3.6-only features to make rollback run more efficiently;
      • The existing implementation carried forward from 3.4 that will be used as a fallback in the case where the new rollback algorithm is unable to revert operations in the oplog generated by a 3.4 server.

      To support both implementations, a server parameter will be introduced to support the fallback behavior and to facilitate regression testing.
