Abstract
Techniques for generating and leveraging a multi-snapshot HNSW index are provided. In one technique, multiple snapshots of an HNSW index that was generated based on a vector table comprising an initial set of vectors are stored. Each of snapshots has a different build time and is associated with a shared journal that stores a plurality of changes to a plurality of vectors in the vector table. A latest snapshot of the plurality of snapshots is identified. The shared journal is identified. It is determined, based on one or more criteria, whether to generate a new snapshot based on the latest snapshot and the shared journal. In another technique, in response to receiving a vector query that is associated with a timestamp, a particular snapshot is selected from the snapshots based on the timestamp. The vector query is executed against the particular snapshot and the shared journal.
