Hacker News with Generative AI: Vector Databases

Sharding Pgvector (pgdog.dev)
If you find yourself working with embeddings, you’ve shopped around for a vector database. pgvector is a great option if you’re using Postgres already. Once you reach a certain scale (about a million arrays), building indices starts taking a long time. Some workarounds, like parallel workers, help, but you still need to fit the whole graph in memory.

Ask HN: Alternatives to Vector DB? (ycombinator.com)
A while back I was looking for a vector database that would work across Windows / Mac / Linux platforms. Some of the options required specific processors like Intel. I am curious if there are any alternatives to a Vector DB that can run cross platform and are easy to setup?

Why Vector DBs Are the Wrong Abstraction – and What We Built Instead (topk.io)
We’ve spent the last three years building the most popular vector database on the market. In that time we realized that a database built around vectors as a primary key is simply the wrong abstraction, creating an unnecessary obstacle for users in production.

Show HN: Tinyhnsw – The Littlest Vector Database (github.com/jbarrow)
TinyHNSW is a tiny, simple vector database. It weighs in at a measly few hundred lines of code. It's built on a straightforward (but not fast) implementation of HNSW in Python with minimal dependencies. It has an associated set of tutorials that build up to understanding how HNSW works, and how you can build your own TinyHNSW.

Why HNSW is not the answer and disk-based alternatives might be more practical (pgvecto.rs)
HNSW (Hierarchical Navigable Small World) has become the go-to algorithm for many vector databases. Its multi-layered graph structure and ability to efficiently navigate vector embeddings make it particularly appealing. However, despite its apparent advantages, HNSW may not be the optimal solution for large-scale and dynamic vector similarity search. In this blog post, we challenge the dominance of HNSW and explore why disk-based alternatives, such as IVF (Inverted File Index), might be more practical for massive datasets.

Scaling Document Data Extraction with LLMs and Vector Databases (timescale.com)
Extracting structured data from unstructured documents is a powerful use case for large language models (LLMs). This sort of data extraction from complex documents has always remained a challenge. Done either completely manually or using current intelligent document processing (IDP) platforms that utilize previous-generation machine learning or natural language processing (NLP) techniques is very time-consuming and tedious.

A Vector Database Plays Mario Kart 64 (medium.com)
In this article, I’ll introduce you to an original application of image search. I’ve named it Qdrant Kart, and, as you might guess, it involves using a Vector Database (Qdrant) to play Mario Kart 64 — one of my all-time favorite games.
