Log writing has been made asynchronous to keep the flows fast. What has the team accepted in exchange?

選択肢

1. The last lines before an abrupt stop may never be written, so the order of the lines becomes unpredictable.
2. The last lines before an abrupt stop may never be written, so the moment of the crash can stay unrecorded.
3. The whole file may be rewritten on restart, so the lines from the previous run are replaced by the new ones.
4. The detail of each line may be reduced, so the values that the flow computed are trimmed before writing.
