SSE

The sse service is responsible for sending sse (Server-Sent Events) to a user. See What is Server-Sent Events for a simple introduction and examples of server sent events.

The Log Service Ecosystem

Log services like the userlog, clientlog and sse are responsible for composing notifications for a certain audience.

• The userlog service translates and adjusts messages to be human readable.
• The clientlog service composes machine readable messages, so clients can act without the need to query the server.
• The sse service is only responsible for sending these messages. It does not care about their form or language.

Subscribing

Clients can subscribe to the /sse endpoint to be informed by the server when an event happens. The sse endpoint will respect language changes of the user without needing to reconnect. Note that SSE has a limitation of six open connections per browser which can be reached if one has opened various tabs of the Web UI pointing to the same Infinite Scale instance.
