But also, I don't think we have any measurements yet that show how
concerned/picky we need to be about how it's implemented?

True that. A {{std::vector}} is not that much slower in terms of speed, it's
just that it has some constant space overhead, roughly ~24 bytes. I cannot
gauge how many UUID objects reside in memory at the same time, but this may be
the ultimate measure.
> Option to extend uids to 128 bit
> --------------------------------
>
> Key: BIT-1016
> URL: https://bro-tracker.atlassian.net/browse/BIT-1016
> Project: Bro Issue Tracker
> Issue Type: New Feature
> Components: Bro
> Affects Versions: git/master
> Reporter: rhave
> Assignee: Jon Siwek
> Priority: Low
> Fix For: 2.2
>
>
> Bro's uids are currently 64 bits, which makes them collide with a 50% chance
> after 5.1 x 10^9^ different uids (see
> http://en.wikipedia.org/wiki/Birthday_problem#Probability_table).
> I'm currently generating uuids of 128 bit to replace the native uids in bro,
> as I'm using them as keys in a database, but this requires rewriting of the
> bro-logs. I suspect that more people could benefit from an option to extend
> the uids to 128 bit.
> I've made a quick and dirty patch to change most of the uids to 128 bit
> (file_analysis uids are missing). The patch is ugly, and is only to show some
> of the functionality I would like: http://pastebin.com/GkaGejNc
