    Description

      Columnstore has internal metadata deltas stored in a file called BRM_saves_journal.
      By default every 100K BRM changes a new BRM_saves version is saved. Starting with BRM_savesA then BRM_savesB. The current version is tracked in BRM_saves_current.

      The problem occurs when the system BRM_saves_current=BRM_savesB and the system inproperly shutdown or cant complete. On startup, the system complains
