Diskann Explained Milvus Blog Learn how diskann delivers billion scale vector searches using ssds, balancing low memory usage, high accuracy, and scalable performance. I am running the docker based default installation of milvus standalone server (v2.2.11), and i'm using it to index 18 million bert embeddings (each having 768 dimensions) with a diskann index.
Diskann Explained Milvus Blog What is diskann? diskann uses a flat graph structure optimized for disk access, allowing it to handle billion scale datasets with a fraction of the memory footprint required by in memory. In this tutorial, we'll dive into diskann, a graph based vector index that enables large scale storage, indexing, and search of vectors by persisting the bulk of the index on nvme hard disks. We present a new graph based indexing and search system called diskann that can index, store, and search a billion point database on a single workstation with just 64gb ram and an inexpensive solid state drive (ssd). This article introduces an on disk indexing algorithm named diskann. based on vamana graphs, diskann powers efficient searches within large datasets. to improve query performance, you can specify an index type for each vector field. currently, a vector field only supports one index type.

By default, diskann is disabled in milvus to prioritize the speed of in memory indexes for datasets that fit comfortably in ram. however, if you’re working with massive datasets or want to take advantage of diskann 's scalability and ssd optimization, you can easily enable it. This paper presents an ssd resident anns scheme called diskann, which can effectively support search on large scale datasets. this scheme is based on a graph based algorithm presented in this paper: vamana. We're thrilled to announce the preview of diskann, a leading vector indexing algorithm, on azure database for postgresql flexible server!. Diskann is particularly suitable for applications requiring large scale vector search on commodity hardware. this article will explain the clever methods diskann has to leverage ssd in addition to ram and reduce costly ssd reads.
