How do you broadcast WebSocket messages to all clients across server nodes?
Source: pypi.orgadvanced
Tests WebSocket horizontal scaling and pub/sub backplanes. A strong answer names a broker like Redis, describes cross-node fan-out, and keeps connection state purely local.
Tests whether you understand the shared-nothing constraint of WebSocket servers and how to bridge them across a cluster. A strong answer names a message broker such as Redis Pub/Sub or Kafka as a backplane, explains that each node subscribes to a broadcast channel and forwards messages only to its own connected clients, and notes that connection state stays in-memory on the local process.
