The BigANN challenge is an important competition in the vector search domain, fostering the development of indexing data structures and search algorithms. Zilliz's solution dominated all four tracks of BigANN 2023, achieving a remarkable up to 2.5x performance improvement. This year's BigANN introduced more significant challenges with larger datasets and complex scenarios across four tracks: filtered, out-of-distribution, sparse, and streaming variants of ANNS. Zilliz's solution is based on graph algorithms and optimizations driven by the specific characteristics of each track. The company plans to integrate these insights into their products, extending their impact on a broader range of issues.
