Polaris: Enabling Transaction Priority in Optimistic Concurrency Control

Summary: Polaris adds multi-level priorities to optimistic concurrency control via a lightweight reservation, introducing minimal pessimism to enforce cross-priority progress. Results show high-priority p999 latency 13x lower than low-priority; 1.9x throughput and 17x tail-latency improvement versus Silo under contention. (summarized by gpt-5-nano on Feb 09 2026)
