Hey vryotek, short version: stickiness is not necessary or important. It does use a websocket.

To elaborate a bit, while each LiveView client is indeed associated with a long lived process in the LiveView server, the Phoenix framework provides hooks and other lifecycle management tools to minimize the impact of disconnects from eg blue green server deploys. Most interestingly for example with forms, the "automatic form recovery" does a process where when the reconnect happens it delays re-rendering until the client side has had a chance to send the current form state back to the server and allow it to synchronize.
