mongodb-instance-model

A MongoDB instance model used internally by MongoDB Compass to represent database instances with properties like host, port, topology, and replica set state. Version 12.49.0 is current, with frequent releases tied to Compass. It is a core abstraction within the Compass data layer but not intended for standalone use. Differentiates as a stateful model with change events, built on top of the MongoDB Node.js driver's topology monitoring.
