Thank you for sharing! DiskANN was published in 2019 and SpeedANN in 2022. DiskANN is specialized in disk based ANNS solution, and it's focus on the scenario where the vectors don't fit into memory. SpeedANN is in-memory solution and specialize in low latency query, which is the scenario we want to tackle for now. We can further extend our engine to support DiskANN and other index algorithms based on our customer's requirements Thanks for pointing out the benchmark figure, we just fixed it to have consistent colors
