Description

We cannot serve event streaming clients with a regular HTTP connection. We need to keep the connection open and regularly flush the output after sending out each event. This requires websockets.

Scope of this JIRA:

• add new endpoint for streaming
• set up websocket connection
• register a new listener to the event handlers so we can receive every update
