> When the graph we need to work on is already partitioned into a fixed number of buckets,
with properties such as high edge-locality, low fan-out to other buckets, etc.  [for instance
using techniques such as https://people.cam.cornell.edu/~jugander/papers/wsdm13-blp.pdf ]
> we should be able to partition our graph based on such a mapping, to improve local-requests,
etc. thus avoiding huge network communication. this diff is especially useful we repeatedly
run algorithms on top of the same graph. In such case, we can compute the partitioning once
& then use it to speed up processing, (also requiring less network bandwidth, etc.) for
the rest applications on same/ similar graphs.
> The diff is big & partly reviewed by my colleagues. Putting it up for review
