The ad portrayed Ring’s Search Party feature, notably different than the Community Requests feature Ring and Flock had initially partnered on to integrate technologies. Ring terminated its contract with Flock Safety, an AI-powered license reader used by (or, formerly for some) police precincts across the country. Flock, a company that sells networks of roadside cameras and software to police departments, businesses, and neighborhoods to identify vehicles and feed that data into searchable law-enforcement databases, is active in more than 5,000 U.S. cities. The software scans license plates and uses integrated video tools to log plates, time, and location, then alerts police when a vehicle matches a “hot list” or is linked to an investigation.
This may seem exaggerated but trust me, it actually a quite accurate description of how the storage engine is designed. The committed state for the whole database in a SpacetimeDB instance is wrapped in a single Read-Write Mutex. All write operations happen sequentially, which is indeed trivial proof of linearizability. Two writes cannot happen at the same time, so they cannot conflict or race. But a read and a write cannot happen at the same time either!
