Yes, my toy tool is similar by the concept to graphchi. But I did not write the vertex-centric processing from scratch and I'm relying on DataFusion built-ins (select, join, group by, aggregate)
It looks similar to networkit in that it represents graphs using row oriented memory layout.
I forked networkit for exactly this reason. Columnar memory is much more efficient.
I got to use graphchi/graphlab back in the day (I think I still have the tshirt from the 2013 conference), wish it had caught on more.
