問題文
A hospital group's reporting store subscribes to change notifications. A network problem kept it disconnected for five days over a holiday. The team reconnects and asks for everything it missed. What should the recovery procedure say?
選択肢
- The retention window can be extended on request so that this does not happen again.
- Replay only covers the retention window, so an outage longer than that needs a reconciliation step that compares the two data sets and repairs the difference.
- Replay covers everything since the subscriber last connected, so simply resuming from the recorded position is enough.
- The subscriber should be rebuilt from scratch by copying the whole data set again, because that is the only way to be certain the reporting store matches and it removes any need to reason about which records were touched during the five days.
