> Range-based partitioning can drastically reduce network communication when using a vertex id space where close ids correspond to vertices likely to be connected.
> We currently have an incomplete implementation of range-based partitioning that tries to be very generic (allowing arbitrarily different partition sizes).
> Talking about this with Avery, we thought that for now it's better to add a simpler version (which tries to split as evenly as possible) and leave the current classes there in case someone wants to implement a more complex logic.
> A nice-to-have is also extending the pseudo-random formats to generate a required ratio of partition-local edges, in order to estimate the impact of locality with benchmarks.
