MMAPv1 LSNFile may be updated ahead of what is synced to data files

        Details

        • Backwards Compatibility:
          Fully Compatible
        • Operating System:

          Description

          MMAPv1 journalling tracks the LSN of the last write to be fsynced to the data files so it knows where to start applying the journal file during recovery. Due to a sequencing error in how it is updated, it may be ahead of what is actually synced to the data files.
