      Description

      Upstream Facebook MySQL has a feature that forces the SE to begin skipping unique checks if a slave lags too far behind the master. This is IMHO a very dangerous feature. It is either safe to skip unique checks always, or it is not. This feature has both a server side component and a MyRocks side component. This task is to track the removal of the MyRocks side from the imported MyRocks codebase.
