Narwhal: Breaking the Local Boundary via Disaggregated Memory Scheduling for Alibaba AnalyticDB

Summary: Narwhal co-schedules local DRAM with an RDMA-disaggregated shared pool, breaking per-machine memory boundaries for bursty OLAP. Hardware-isolated quotas/QoS, a database-aware three-tier cache, and pressure invariants prevent OOMs while enabling high oversubscription with minimal remote borrowing.
