A lot of things happened in the graph space so far. Here’s a quick summary with a few comments.

  • On DB Engines ranking, graph databases have continued their rebound and have been on a growth trajectory for the last 5 months.
  • In 2021, Gartner predicted that “by 2025, graph technologies will be used in 80% of data and analytics innovations, up from 10% in 2021, facilitating rapid decision making across the organization”. While this is difficult to verify, my feeling is that this prediction failed and has been quietly swept under the rug. There is no mention of it on Gartner’s site or social media feeds.
  • RDF 1.2 is out. RDF 1.1 was released more than 11 years ago so this is a big deal in the semantic web community.
  • DuckDB v1.3.0 was released with support for the USING KEY clause in recursive common table expressions. This new clause, implemented by researchers at the University of Tübingen based on their CIDR 2023 paper, allows making recursive CTEs much more efficient.
  • Kùzu v0.10.0 is out. Kùzu continues to be a strong player in the open-source analytical graph database category and it’s good to see it mature.
  • The programme of SIGMOD 2025 has been announced and its full of good graph talks. I will attend the event in June.
