Chapter 1. Overview of client-side notifications
When actions and state changes occur in the Cryostat backend, Cryostat uses a WebSocket connection to show notifications in your Cryostat web client.
In Cryostat 2.2, notifications display for all conceptual actions and state changes. These notifications are prevalent when you configure automated rules. Cryostat 2.2 includes notification settings that you can configure to reduce the high volume of notifications that might display on your Cryostat web console.
Previously, updating a resource involved sending an HTTP GET request to retrieve and replace the entire list of resources. With Cryostat 2.2, web-client performance is improved by using notifications to update the state of resources. For example, when you delete an active recording, a notification is sent to the Cryostat web console. The web console deletes the recording from the active recordings list.
