Hi @gallenvara, @greghogan,
- If it's possible to return both the hub and the authority value, I'd
prefer that.
- GSA iterations allow setting the edge direction as Greg suggested. I'm
not sure how much of a difference the combiner would make. Also, we've seen
that for some graphs scatter-gather performs better. Personally, I would be
fine with a first scatter-gather version of the algorithm. We can run some
tests to see whether GSA would be faster later.
- I agree that edge values should be internally set to `NullValue` if not
used.
