      This POC was about introducing a way to lock the change collection before entering the timestamped unit of work.

       

      Essentially taking the change collection lock within the AutoGetChangeCollection().

       

      The POC work is here: https://spruce.mongodb.com/version/62895d357742ae5ac3399275/changes?sorts=STATUS%3AASC%3BBASE_STATUS%3ADESC

       

      Ultimately, it was decided to not go with this path as this solution is prone to deadlocks and is difficult to debug.

       

      An alternate suggestion has been proposed here: https://jira.mongodb.org/browse/SERVER-66715
