HeraDB: Towards Real-time Analysis of Transaction-Centric HTAP with CPU-GPU Hybrid Query Execution
Summary: HeraDB targets transaction-centric HTAP, combining GPU scans of a stale column snapshot with CPU processing of fresh deltas to deliver current results while isolating OLTP performance. Timestamp filters and lightweight log synchronization avoid bulk PCIe transfers, yielding up to 11.1× higher TP and 5.9× higher AP throughput than Colibri. (summarized by gpt-6-luna on Oct 22 2026)
