Post author here. Yes, you are correct. I was doing this code change 3 years ago when I was a junior dev, I was not familiar with a blocked bloom filters at that time. Looking back, it’s cool to see that I accidentally reinvented a basic blocked bloom.

I was also limited by the constraint of legacy code. This project was not a complete rewrite, but just an idea: "can we use more information from that 32-bit hash that we recieve in without regressing any perf". We didn't have a time for a deep research or a rewrite, so I just wanted to show the result of this small exercise on how we can make things run better without rewriting the world.
