Let’s build something Outrageous – Part 17: Bulk Traversals

A few years ago I was really angry at the traversal performance I was getting on some slow query. So angry that I wrote a couple thousand lines of C code just to calm myself down. This is how Neo4c came about. This blog post explains the just of it. Neo4c was able to crank out 330 million traversals per second on a single core (because it was single threaded code) for a hand crafted “query” written in C using 32 bit ids (so limited to 4b nodes and 4b relationships). It wasn’t really a fair comparison to Neo4j, but it made me realize there was a lot of performance out there to be had. Let’s see where we are today.
