In ABN Techweek this week, we look at Vector DB and why they are useful. Lets dive in.

Vector databases are so hot right now, but what is a Vector DB?
The diagram below shows a comparison between a vector database and other types of databases.
🔹 A vector database indexes and stores vector embeddings for fast retrieval and similarity search, with capabilities like CRUD operations, metadata filtering, and horizontal scaling.
🔹 Recent advances in AGI (Artificial General Intelligence) have made vector databases so popular.
🔹 A vector database stores high-dimensional vectors extracted from various unstructured data, like audio, video, image, and text. Then we can calculate the similarity among unstructured data. Typical use cases include:
- finding similar images or text
- recommending similar products
- detecting abnormalities
- temporarily store embeddings for large amounts of input
🔹 There has been a great deal of funding raised by vector database companies:
- Pinecone: $138 million
- Milvus: $113 million
- Weaviate: $67.7 million
- Chroma: $20 million
- Qdrant: $9.8 million
Over to you: Redis, ElasticSearch, and PostgreSQL support vector data processing. Are specialized vector databases necessary?
