HyperPage optimizes disk-resident graph vector indexes using learned layouts

By PulseAugur Editorial · [1 sources] ·

Researchers have developed HyperPage, a novel method for optimizing disk-resident graph vector indexes. Unlike previous layouts like Starling and MARGO, HyperPage utilizes reinforcement learning and logs of search agent traversals to create page layouts tailored to specific memory budgets. This approach aims to minimize page reads by intelligently grouping records and their associated graph edges on SSD pages. Testing showed HyperPage reduced page reads by 5.2% to 21.2% compared to MARGO across various cache budgets, with the most significant improvements seen at smaller cache sizes. AI

IMPACT This research could lead to more efficient storage and retrieval of large vector datasets, impacting AI applications that rely on similarity search.

    HyperPage: Learned Page Layouts for Disk-Resident Graph Vector Indexes

    Disk-resident graph indexes such as DiskANN store each vector with its graph edges as one record on SSD pages. A search needs the page of every record it expands, so its page reads depend on the page layout, that is, which records share a page. Search agents trained with reinforc…
