Introducing Cardinal: The Most Performant Engine For Vector Searches

Cardinal is a new vector search engine developed by Zilliz, which has demonstrated a threefold increase in performance compared to the previous version. It offers a search performance (QPS) that reaches tenfold that of Milvus. Cardinal is capable of performing brute-force search, creating and modifying ANNS indices, working with various input data formats, and filtering results during the search based on user-provided criteria. The key to Cardinal's speed lies in its algorithm optimizations, engineering optimizations, low-level optimizations, and AutoIndex feature for search strategy selection.
