So you would definitely not like #2 and probably not #1.

In our case a repetition is not a highly critical problem. (Not enough to justify using a centralized sequence generator.) Repetition just reduces the readability of the logs. Given that the logs are even less readable without these id's I'd say we are in a better position to implement something rather than nothing. -- JT Moree
