RecoveryUnit ------------ -**Q**: Should RecoveryUnit::syncDataAndTruncateJournal be static or in a different class? I am not -sure why they need to effect the instance of RecoveryUnit? -**A**: These methods are effectively static in that they will only modify global -state. However, these methods are virtual, which is why we aren’t declaring them -as static. That being said, we will likely remove this methods from the public -API and move them into our mmapv1 storage engine implementation in the near -future. - -**Q**: RecoveryUnit::syncDataAndTruncateJournal sounds like a checkpoint. That can -take a long time, is this expected to block until that is done? -**A**: Yes. Note that this is only called externally when we drop a database or when -the user explicitly requests a sync via the fsync command. We may rename this -method as part of a naming sweep. - **Q**: As documented I don’t understand the point of the RecoverUnit::endUnitOfWork nesting behavior. Can you explain where it is used or will be used? **A**: The RecoveryUnit interface and the mmapv1 (current mongodb storage engine) |
