Vector search captures the meaning and context of unstructured data, and is commonly used for text or image processing, enabling the use of semantics to find similar results and obtain more valid results than traditional keyword retrieval.

Databend plans to provide users with a richer and more efficient means of querying by supporting vector search, and the introduction of Faiss Index may be an initial solution.

Issue 9699: feat: vector search (Faiss index)
