Vector Databases Book

It’s a small book 292 pages category : Intermediate to Advanced.

I just finished reading it today it take me 2 days to finish reading it’s with my whole respect to the author.

A very bad book from multiple points i will share.

This is not related to the author knowledge or anything just my thought about the book.

The topics

  1. Intro to databases
  2. Embeddings
  3. FAISS
  4. SQLite3
  5. POstgresSQL pygvector
  6. SQLite and Ollama
  7. Complete RAG system app
  8. Vector Query Language.

shiny and nice topics.

Vector database Book Review.

When you read the book you would feel it’s not connected with each other in a nice way. it’s like listing some information from GitHub pages without the sense of teaching.

a lot of chapters listing info that is specific to Project which if i need it i will read GitHub page.

The Charts are not that helpful they don’t add more value just an overview it’s more like AI generated one. It maybe not AI but not much helpful.

You feel there is a gab between the depth of knowledge and the titles. shiny titles.

I hoped it was more detailed more to concepts with nice explaining that works with any vector database.

  • Example the FAISS chapter :
    • it gives all the indexing types in FAISS and quick overview about quantization that is bad then benefit and trade offs this is style of book!

My Recommendation.

Any Vector database Articles are far helpful and much better like :

Quarto Blogs.

Weaviate

Who am I ?

I am just 2 years experience in AI and RAG but it’s obvious it’s not good book.
