Concurrency Control as a Service
Summary: CCaaS decouples concurrency control into an independently scalable execution–CC–storage layer, addressing CC’s bottleneck in disaggregated databases. Its sharded multi-write OCC, asynchronous log push-down, and deterministic conflict resolution reduce network and coordination overhead. (summarized by gpt-5.6-luna on Jul 24 2026)
