The diagram shows multiple client connections to each Cloud Run instance. This sample uses Redis's conventional functionality of an object store to cache and retrieve message history. To load prior messages, message history would need to be stored and retrieved from a persistent storage solution. However, even with push updates, any instance that is spun up will only receive new messages pushed to the container. Redis uses a Pub/Sub mechanism, not to be confused with the product Cloud Pub/Sub, to push data to subscribed clients connected to any instance, to eliminate HTTP polling for updates. This sample chat service uses a Memorystore for Redis instance to store and synchronize user messages across all instances.
Just between the clients connected to one instance. In the chat service need to be synchronized across all instances, not Potentially routed to a different instance. With WebSockets, both client and server can push messages to each other without polling the server for updates.Īlthough you can configure Cloud Run to useīest effort affinity, which means that any new request can still be
