Watch stream for Node objects in the cluster. Node events include registration of new nodes, condition changes (Ready, MemoryPressure), and node deletions during scale-down or maintenance.
The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.
