This would seem like a sensible approach to me.
I have worked with many different graph databases, and it is quite
normal to load the nodes or entities first, and then add the
relationships or links second.
Maybe one can add all the bugs first, without any relationships/links.
Then build up a map of github IDs vs bugzilla IDs, and then use that
map to then add all the relationships afterwards using the learnt
bugzilla IDs.
Or, alternatively, use your current method, and then scan over
everything at the end, to add in any relationships that got missed
using the above approach.

Kind Regards
