MariaDB Vector: How it works
You might have seen that MariaDB Vector is fast. And is getting faster. But why? How does it achieve that? And why it is said to use mHNSW (modified HNSW) algorithm? What did it modify in the conventional HNSW that all other databases are using? Let’s take it apart and analyze piece by piece.

MariaDB vs PostgreSQL: Understanding the Architectural Differences That Matter
This blog post is based on the YouTube presentation “MariaDB vs PostgreSQL: Technical Deep Dive | Architecture, Performance & Design Trade-offs” by Manoj Vakeel, part of MariaDB Foundation’s ongoing series exploring core database design choices and how they impact modern workloads.
The goal here is not to pick a “winner,” but to provide clear architectural insight for CTOs, database engineers, and system architects making decisions in 2025 and beyond.
“Both are powerful engines — both are proven in production — […]
