Billion‑edge graph analytics on a laptop with Apache DataFusion
Apache DataFusion processes billion‑edge graphs on a laptop by offloading scans, joins and aggregations to disk and using spill‑aware execution. The author runs PageRank on a 1 billion‑edge graph with 5 GB RAM and finds weakly connected components in a 2 billion‑edge graph using 10 GB, beating traditional in‑memory tools.
