    CHRONOS: Temporally-Aware Multi-Agent Coordination for Evolving Data Marketplaces

    Joydeep Chandra

    cs.DB · cs.AI · cs.CR · cs.LG · cs.MA

    Temporal knowledge-graph data marketplaces face three coupled failures in static designs: stale hybrid index shortcuts reduce recall as edges evolve, stationary Shapley pricing misattributes value after distribution shifts, and uncoordinated agents over-consume a shared differential-privacy budget. We present CHRONOS, a three-layer architecture providing a unified treatment of these challenges with explicit public and private separation....

    A Pragmatic Approach to Learned Indexing in RocksDB: Targeted Optimizations with Minimal System Modification

    Shubham Vashisth, Olivier Michaud, Bettina Kemme, Oana Balmau

    cs.DB · cs.DC

    Learned indexes have emerged as a promising alternative to traditional index structures, offering higher throughput and lower memory usage by approximating the cumulative key distribution function with lightweight models. Despite these benefits, adoption in production systems remains limited, partly because learned indexes that support concurrency and persistence as effectively as, e.g., the B+-Tree, do not yet exist, while many research...
