Abstract
Techniques for providing a transactionally-consistent Hierarchical Navigable Small Worlds (HNSW) index are described. In one technique, a HNSW index for a plurality of vectors is stored. In response to receiving a set of changes to the plurality of vectors, storing the set of changes in a shared journal table instead of applying the set of changes to the HNSW index. in response to receiving a vector query that includes a query vector, a subset of the set of changes in the shared journal table is identified based on the query vector. Also, based on the query vector and the HNSW index, a subset of the plurality of vectors is identified. A result of the vector query is generated based on the subset of the set of changes and the subset of the plurality of vectors.
