In this blog post, KuzuDB creator Semih Salihoğlu makes the case that graph databases need new join algorithms. If you’ve read the blog post and came away still a bit confused then look at the image above. This image shows what happens when you try to join 3 tables. The problem is that traditionally databases have used binary joins (two tables at a time) to execute queries. The intermediate result build up of these joins can get massive and eat a ton of memory and processing power. The more binary joins you have, the worse it gets.
